Part – III

Answer any seven questions (Q.No: 32 is compulsory) [7 × 4 = 28]

Question 23.
Describe the rocket propulsion.
Answer:

• Propulsion of rockets is based on the law of conservation of linear momentum as well as Newton’s III law of motion.
• Rockets are filled with a fuel (either liquid or solid) in the propellant tank. When the rocket is fired, this fuel is burnt and a hot gas is ejected with a high speed from the nozzle of the rocket, producing a huge momentum.
• To balance this momentum, an equal and opposite reaction force is produced in the combustion chamber, which makes the rocket project forward.
• While in motion, the mass of the rocket gradually decreases, until the fuel is completely burnt out.
• Since, there is no net external force acting on it, the linear momentum of the system is conserved.
• The mass of the rocket decreases with altitude, which results in the gradual increase in velocity of the rocket.
• At one stage, it reaches a velocity, which is sufficient to just escape from the gravitational pull of the Earth. This velocity is called escape velocity.

Question 24.
Explain the types of Scattering.
Answer:
Types of Scattering.
When a beam of light, interacts with a constituent particle of the medium, it undergoes many kinds of scattering.
Based on initial and final energy of the light beam, scattering can be classified as,

1. Elastic scattering
2. Inelastic scattering

1. Elastic scattering:
If the energy of the incident beam of light and the scattered beam of light are same, then it is called as ‘elastic scattering’.

2. Inelastic scattering:
If the energy of the incident beam of light and the scattered beam of light are not same, then it is called as ‘inelastic scattering’.
The nature and size of the scattered results in different types of scattering. They are

• Raylight scattering
• Mie scattering
• Tyndall scattering
• Raman scattering

Question 25.
(a) Calculate the current and the resistance of a 100 W, 200 V electric bulb in an electric circuit.
Answer:
Given, P = 100 W, V = 200 V
Power P = VI

(b) What is the role of the earth wire in domestic circuits?
Answer:

• The earth wire provides a low resistance path to the electric current.
• The earth wire sends the current from the body of the appliance to the Earth, whenever a live wire accidentally touches the body of the metallic electric appliance.
• Thus, the earth wire serves as a protective conductor, which saves us from electric shocks.

Question 26.
Explain the mechanism of cleansing action of soap.
Answer:
A soap molecule contains two chemically distinct parts that interact differently with water. It has one polar end, which is a short head with a carboxylate group (-COONa) and one nonpolar end having the long tail made of the hydrocarbon chain.

The polar end is hydrophilic (Water loving) in nature and this end is attracted towards water. The non-polar end is hydrophobic (Water hating) in nature and it is attracted towards dirt or oil on the cloth, but not attracted towards water. Thus, the hydrophobic part of the soap molecule traps the dirt and the hydrophilic part makes the entire molecule soluble in water.

When a soap or detergent is dissolved in water, the molecules join together as clusters called ‘micelles’. Their long hydrocarbon chains attach themselves to the oil and dirt. The dirt is thus surrounded by the non-polar end of the soap molecules. The charged carboxylate end of the soap molecules makes the micelles soluble in water. Thus, the dirt is washed away with the soap.

Question 27.
(a) Explain the various types of binary solutions based on the physical states of solute and solvent table.
Answer:

(b) State Henry’s law?
Answer:
Henry’s law states that, the solubility of a gas in a liquid, is directly proportional to the pressure of the gas over the solution at a definite temperature.

Question 28.

Answer:
Playing harmonium by striking a particular key, on seeing a music note is an example of conditioned reflexes which required conscious training effort.

(b) How many cranial nerves and spinal nerves are present in man?
Answer:
12 pairs of cranial nerves and 31 pairs of spinal nerves are present in man.

Question 29.
(a) What are Allosomes?
Answer:
Allosomes are chromosomes which are responsible for determining the sex of an individual. There are two types of sex chromosomes. X and Y chromosomes. Human male have one X chromosome and one Y chromosomes and the human female have two X chromosomes.

(b) What causes the opening and closing of guard cells of stomata during transpiration?
Answer:
The opening and closing of stomata is due to the change in turgidity of the guard cells. When the water enters into the guard cells, they become turgid and the stomata open. When guard cells lose water, it becomes flaccid and the stomata closes.

Question 30.
(a) Draw and label the structure of oxysomes
Answer:

(b) What is respiratory quotient?
Answer:
The ratio of volume of carbon dioxide liberated and the volume of oxygen consumed, during respiration is called Respiratory Quotient (R.Q)

Question 31.

(ii) Explain the construction and working of a ‘compound microscope’.
Answer:
Construction
A compound microscope consists of two convex lenses. The lens with the shorter focal length is placed near the object, and is called as ‘objective lens’ or ‘objective piece’. The lens with larger focal length and larger aperture placed near the observer’s eye is called as ‘eye lens’ or ‘eye piece’. Both the lenses are fixed in a narrow tube with adjustable provision.

Working:
(i) The object (AB) is placed at a distance slightly greater than the focal length of objective lens (u >fo).
(ii) A real, inverted and magnified image (A’B’) is formed at the other side of the objective lens.
(iii) This image behaves as the object for the eye lens. The position of the eye lens is adjusted in such a way, that the image (A’B’) falls within the principal focus of the eye piece.
(iv) This eye piece forms a virtual, enlarged and erect image (A” B”) on the same side of the object.
(v) Compound microscope has 50 to 200 times more magnification power than simple microscope.

(b) (i) In what way hygroscopic substances differ from deliquescent substances.
Answer:
Difference between hygroscopic and deliquescent substances is in the extent to which each material can absorb moisture. This is because both of these terms are very much related to each other and they refer to the property of observing and the retention of moisture from the air. However, they differ in the extent of absorption of moisture where hygroscopic materials absorb moisture but not the extent the original substance dissolves in it, which is the casewith deliquescence. Therefore deliquescence can be regarded as an extreme condition of hygroscopic activity.

(ii) Define solubility.
Answer:
It is defined as the number of grams of a solute that can be dissolved in 100 g of a solvent to form its saturated solution at a given temperature and pressure.

Question 35.

(ii) How does binary fission differ from multiple fission?
Answer:

(iii) What are the sources of solid wastes? How are solid wastes managed?
Answer:
Solid wastes mainly include municipal wastes, hospital wastes, industrial wastes and e-wastes, etc.

Methods of solid wastes disposal:
(1) Segregation: It is the separation of different type of waste materials like biodegradable and non-biodegradable wastes.

(2) Sanitary landfill: Solid wastes are dumped into low lying areas. The layers are compacted by trucks to allow settlement. The waste materials get stabilised in about 2-12 months. The organic matter undergoes decomposition.

Question 33.
Narrate the history of transformation of Council of Europe into an European Union.
Answer:
(i) After World War II, it was decided to integrate the states of western Europe. One of the chief objectives was to prevent further European wars by ending the rivalry between France and Germany. In May 1949, ten countries met in London and signed a form called Council of Europe.

(ii) Since the Council of Europe had no real power, a proposal to set up two European organisations were made. Accordingly, the European Defence Community (EDC) and the European Coal and Steel Community (ECSC) were established. Six countries belonging to ECSC signed the treaty of Rome which established the European Economic Community (EEC) or the European Common Market, with headquarters at Brussels.

(iii) The EEC facilitated the elimination of barriers to the movement of goods and services, capital, and labour. It also prohibited public policies or private agreements that restricted market comptetion. Throughout the 1970s and 80s the EEC kept expanding its membership.

Question 29.
‘Maddened by hunger, he dived at the fish,’ says the narrator about the young seagull. Do you feel hunger was the main motivating force that made the young seagull take the plunge that taught him how to fly in the air?
Answer:
Food is the most essential ingredient that sustains all life – of humans, animals as well as birds. Hunger motivates many of their actions. The young seagull used to sit all alone on his ledge. Whenever he tried to flap his wings to fly, he was seized with fear. He felt certain that his wings would never support him.

He had seen his older brother catch his first herring and devour it. It compounded his helplessness even more. He uttered a joyful scream when he saw his mother holding a piece of fish in her beak and flying quite near him. He wondered why she didn’t come to him and offer that piece of fish to him. Maddened by hunger, he dived at the fish. With a loud scream he fell outwards and downwards into space.

Then a monstrous terror seized him but only for a minute. The next moment he felt his wings spread outwards. He began to soar downwards towards the sea. The fear left him. He began to float on the sea. His admiring family offered him pieces of fish flying around him.

‘’Your hunger must be absolutely compelling
in order to overcome the obstacles that will
invariably come your way. ”

Question 30.
What makes Culverton Smith fall a prey to Holmes’s trap?
Answer:
Watson goes to Mr. Culverton Smith at 13 Lower Burke Street. He finds it difficult to see his friend dying. Although Smith refuses to see anyone, Watson forces his way in. As soon as Watson explains his errand, Smith’s attitude changes drastically. He persuades him to see Holmes as he is in a dying state. Smith agrees to come to Baker Street within half an hour.

Watson excuses himself, saying that he has another appointment and returns to Baker Street before Smith’s arrival as instructed by Holmes. Believing that they are alone, Smith is frank with Holmes. Holmes tells Smith that he will forget the happenings of Victor Savage and pleads with him to cure him.

Smith denies and tells Holmes that he should have never crossed his path. Smith sees the little ivory box, which he had sent to Holmes by post containing a sharp spring infected with the illness. Smith pockets it thinking to have removed the only evidence of his crime. He then resolves to stay there and watch Holmes die. However, Holmes asks Smith to turn the gas up full, which Smith does. Inspector Morton enters and Holmes tells Morton to arrest Culverton Smith for the murder of his nephew and also for the attempted murder of Sherlock Holmes.

“You cannot escape from a detective s eye.”

Question 31.
Narrate the extensive search operation made by the policemen in the house.
Answer:
The arrival of the police blows the whole event out of proportion. The cops call out for the front door to be opened, and when no one in the house goes downstairs, they break it in. They go upstairs to find the narrator, still walking around with a towel over him after his bath. The mother insists there were burglars though the police confirms that all doors and windows are bolted from inside. The police set about probing the house, moving furniture and emptying closets.

At one point, a policeman’s inquisitiveness makes him point out an unusual old musical instrument, a zither, to another officer. The police are suspicious of the family members’ strange behaviour. When the narrator’s grandfather, sleeping in the attic, makes a slight noise, the policemen spring into action. They race upstairs to investigate. The narrator fears trouble because his grandfather feels that the Civil War is in progress.

When the policemen arrive at his door, he is convinced that they are Meade’s army and calls them deserters. He slaps a policeman sending him to the floor and takes the man’s gun from his holster and shoots at him, hitting him in the shoulder.He fires twice more and then goes back to bed. Back downstairs, the police feel defeated. They bandage the wounded officer and search the house again.

“Wisdom requires not only the investigation of many things but contemplation of the mystery.”

Question 32.
Highlight the factors responsible for the all-women Indian Navy crew to carry out their expedition.
Answer:
The support the crew members received was a major factor. When they knew that they were doing well and looked after themselves well, in spite of all apprehensions they were supportive. The crew members’ personal aim and target mattered a lot. Mostly they wanted to make sure that they complete the journey with ultimate honesty without the use of engines.

Then the destination, the journey was important. So their contention was to make sure that they go by the rules of circumnavigation without any means of repulsion and anybody else’s assistance. The presence of mind and common sense to make decisions and act quickly was an added factor. They had to quickly do an analysis of problem solving techniques.

Ego should never come amidst them. Team work helped them to collaborate and work together. Mutual understanding was important too. One would heat the water while the other would heat the gloves or even rested. Over air the confidence you had in each other than the trust and acceptance as every member of the crew to be a family was a must to carry out the expedition.

“Its about women helping women and women doing things together and supporting each other”

Section – II
Answer any TWO of the following in utmost 10 lines. [2 x 5 = 10]

Question 33.
Compare and contrast the attitude of the ant and the cricket.
Answer:
The poem, ‘The Ant and the Cricket’ is about a careless cricket and a hardworking ant. We all know that ants are hardworking creatures but on the other hand the Cricket is portrayed as a lazy being. He made no efforts to plan for the future. Thus, the cricket is shown as a young and silly creature because he sang all through summer and spring with no worries in the world for winter that was to come. But when winter arrived, he began to complain that he would die of starvation and hunger. He found that his cupboard was empty and not a piece of bread to eat.

He neither found a leaf, nor a flower. Everything was covered with snow. Therefore, the cricket cried and moaned as he perceived his bad future. Finally, deprived of hunger and starvation, being all wet and cold, the cricket journeyed to the house of the stingy ant becoming bold by nature. He begged for food and shelter but the Ant is wise, foresees its needs for winter and prudently turned down the foolish Cricket. The Ant clearly stated that Ants neither borrow nor lend. So the Ant is shown as a straightforward and outspoken personality.

Perhaps the cricket here is portrayed as a person who makes false promises and Ant is portrayed to be a strong personality not carried away be the false promises of one. Therefore the Ant could never be exploited though it was humble enough to admit it to be a servant and friend of the Cricket. The Cricket was surely careless and reckless against the Ant who was judicious, discrete and level-headed.

“Accept responsibility for your life.
Know that it is you who will get you where you want to go, no one else.”

Question 34.
How are we alike? Explain in context with the poem, ‘No Men Are Foreign’.
Answer:
All human-beings are the same. We have a similar body structure. All of us need air to breathe, sunlight and warmth to live and water for our survival. Our daily routine is also similar. We wake up in the morning, bathe and have breakfast before going on with our daily chores. All of us long for love and affection. We all sleep at night and wake up in the morning.

When our needs and feelings are the same, then isn’t it right to treat all men alike? We should not look down upon anybody on the basis of his/her colour, caste, region or gender. We should treat everyone as our brother and sister. Unfortunately, some self-centred people fight with others and hurt them. They think that others have harmed them. We should not think that other people are ‘others’. They are also our brothers. If they make one mistake, we should forgive them or compromise with them.

“Acceptance for one another is the key to living.”

The son’s surprised eyes looked back over the path, then at the poor old, shriveled hands all scratched and soiled by their work of love. His heart broke within and bowing to the ground, he cried aloud: “Oh, honorable mother, your kindness breaks my heart! I will not leave you.

Together we will follow the path of twigs, and together we will die!’’Once more he shouldered his burden (how light it seemed now) and hastened down the path, through the shadows and the moonlight, to the little hut in the valley.

Question 43.
Make notes or write a summary of the following passage.
Answer:
The term earthquake is applied to any tremor or shaking of the ground. Many earthquakes are so gentle as to pass almost unrecognised, others are sufficiently pronounced to excite general alarm, while some spread enormous destruction. Destructive earthquakes are usually confined to limited regions. The usual phenomena recorded in well-known earthquakes are first a trembling, next one or more severe shocks, and then a trembling which gradually dies away. In most cases, each shock lasts only a few seconds, but the tremblings that follow may continue for days, weeks, or even months.

Noises of various kinds usually accompany an earthquake. They have been likened to the howling of storm, the growling of thunder, the clanking and clashing of iron chains, or the rumbling of heavy wagons along a road. Such noises are conducted through the ground, or they may travel through the sea or air, and are often heard at great distances from the place where the shock is felt. Some earthquakes, however, are not accompanied by these noises.

At the time of the terrible shock which destroyed Riobamba in Ecuador on February 4, 1797, a complete silence reigned. Among destructive earthquakes in modem times may be mentioned the one that destroyed coastal towns in Tamil Nadu in 2004.

Question 46.
(а) The plot – Prospero’s revenge – the spirit of Ariel – dirty work – shipwreck – Antonio- a sea storm – shipwreck the crew – A delicious banquet – King of Naples – the lost son – meticulous planning – rivals state of regret – re-establish the legal command – dukedom of Milan – Prospero all-powerful – past conspirators face-to-face the sins of their past, repent and plead forgiveness.
Answer:
The plot in the play, The Tempest, by William Shakespeare revolves around Prospero enacting his revenge on various characters who have wronged him in different ways. Interestingly, he uses the spirit of Ariel to deliver the punishments while Prospero delegates the action. Prospero sends Ariel to do his dirty work while hiding his involvement in shipwrecking his brother, Antonio, from his daughter, Miranda.

He creates a sea storm and makes the vessel to toss and shipwreck the crew. Every member thinks that he is the only one saved. A delicious banquet is placed before the King of Naples that vanishes before they could relish its taste.

At another stage, those who were thought dead were discovered alive. The lost son, Ferdinand is resorted to a joyous father making those who have committed offenses repent. Prospero meticulously plans to bring his rivals to a state of regret so that he can pardon them and re-establish the legal command of things to his dukedom of Milan. Prospero being all¬powerful over the island, can easily destroy or punish his enemies as he wishes. However, he chooses not to and brings the past conspirators face-to- face with the sins of their past, which causes them to repent and plead his forgiveness.

This Futuristic story, written in 1889 speaks about the people of the 29th century who live in fairyland, foreseeing 25th July, 2889 @ the office block of the Managing Editor of the Earth Herald, the world’s largest newspaper where news is not printed but spoken. The day’s work started at the reporters’ room.

His fifteen hundred reporters, with their telephones, were speaking the news received from the four quarters of the earth to subscribers. Besides telephone, all reporters have commutators, which allow communication on telephotic line with visual sights. Bennett questioned one of the ten astronomical reporters Cash about the recent discoveries in the stellar world.

Cash replied that it was Phototelegrams from Mercury, Venus and Mars, and nothing from Jupiter since the Jovians signal could not be understood. He added that even results from the Moon wasn’t possible and one can’t blame optical science though moon was six hundred times nearer than Mars. Corley another reporter said it was the inhabitants which was refuted by Bennett who said the simplest way was to turn the moon round and find out.

From then on, the scientists of the Bennett factory started working on turning satellite. One of the Earth Herald’s astronomers had just determined the elements of the new planet Gandini and Bennett was delighted at his accuracy. He wanted the reporters to pass on the news to the subscribers immediately. The broad gallery for such a journal as the Earth Herald brought in an average of three million dollars daily.

Still for ordinary people success in Los Angeles has been the cause for celebration in the streets. Even schools stayed close.

What the movie celebrates is not India’s cinema which produces hundreds of movies each year drawing an average 23 million spectators per day, but the country and its stories, placed under the limelight of Hollywood for once. The stories of Mumbai’s slum kids, that of muslim boy Jamal and Pinki from Dabai, are but two of the many faces of today’s India, faces always ignored until Slumdog Millionaire’s triumph put the spotlight on them.

And the sound of a voice that is still.

At the foot of thy crags, O Sea!
But the tender grace of a day that is dead Will never come back to me.

Question 33.
Solve the equation 3x³ – 26x² + 52x – 24 = 0 if its roots form a geometric progression
Answer:
The given equation is 3x³ – 26x² + 52x – 24 = 0

Given that the root are GP
∴ The roots are \(\frac{\alpha}{r}\) , α, αr
\(\frac{\alpha}{r}\) x α x αr = (-8)
α³ = 8
α = 2

Question 34.
Find the value of \(\cot \left(\sin ^{-1} \frac{3}{5}+\sin ^{-1} \frac{4}{5}\right)\)
Answer:

Question 35.
If the normal at the point“ t₁‘ on the parabola y² = 4ax meets the parabola again at the point ‘t₂’, then prove that \(t_{2}=-\left(t_{1}+\frac{2}{t_{1}}\right)\)
Answer:
Equation of normal to y² = 4ax at ‘t’ is y + xt = 2at + at³.
So equation of normal at ‘t₁,’ is y + xt₁, = 2at₁ + at₁³ ……….(1)
The normal meets the parabola y² = 4ax at “t₂‘ (ie.,) at (at₂², 2at₂)

Question 36.
Find the coordinates of the foot of the perpendicular drawn from the point (-1, 2, 3) to the straight line \(\vec{r}=(\hat{i}-4 \hat{j}+3 \hat{k})+t(2 \hat{i}+3 \hat{j}+\hat{k})\). Also, find the shortest distance from the given point to the straight line.
Answer:

Comparing the given equation \(\vec{r}=(\hat{i}-4 \hat{j}+3 \hat{k})+t(2 \hat{i}+3 \hat{j}+\hat{k})\) with \(\vec{r}=\vec{a}+t \vec{b}\) we get \(\vec{a}=\hat{i}-4 \hat{j}+3 \hat{k} \hat{k}\) and \(\vec{b}=2 \hat{i}+3 \hat{j}+\hat{k}\). We denote the given point (-1,2,3) by D, and the point (1,-4,3) on the straight line by A . If F is the foot of the perpendicular from D to the straight line, then F is of the form (2t+1, 3t – 4, t + 3) and \(\overrightarrow{\mathrm{DF}}=\overrightarrow{\mathrm{OF}}-\overrightarrow{\mathrm{OD}}=(2 t+2) \hat{i}+(3 t-6) \hat{j}+t \hat{k}\) .
Since \(\vec{b}\) is perpendicular to \(\overrightarrow{\mathrm{DF}}\), we have
Line \(\vec{b} \cdot \overrightarrow{\mathrm{DF}}\) = 0 = 2(2t + 2) + 3(3-6) +1(t) = 0 = t=1
Therefore, the coordinate of F is (3,-1, 4).
Now, the perpendicular distance from the given point to the given line is
\(\mathrm{DF}=|\overrightarrow{\mathrm{DF}}|=\sqrt{4^{2}+(-3)^{2}+1^{2}}=\sqrt{26}\) units.

Question 37.
Find the asymptotes of the curve f(x) = \(\frac{x^{2}+6 x-4}{3 x-6}\)
Answer:
Since the numerator is of highest degree than the denominator. We have a slant
asymptote to find it we have to divide the numerator by the denominator.

So the equation of asymptote is \(y=\frac{x}{3}+\frac{8}{3}\) and 3x – 6 = 0
x = 2

Question 41.
(a) An amount of ₹ 65,000 is invested in three bonds at the rates of 6%, 8% and 10% per annum respectively. The total annual income is ₹ 5,000. The income from the third bond is ₹ 800 more than that from the second bond. Determine the price of each bond. (Use Gaussian elimination method.)
Answer:
Let the amount invested in 6% bond be ₹ x
and the amount invested in 8% bond be ₹y
and the amount invested in 10% bond be ₹z
Now x + y + z = 65000

(i.e) 6x + 8y + 10z = 500000
(÷by 2) 3x + 4y + 5z = 250000
Also given that
\frac{10}{100} z-\frac{8}{100} y = 800 (i.e) -8y + 10z = 80000
(÷ by 2) -4y + 5z = 40000

(i.e,) x + y + z  = 65000…..(1)
y + 2z = 55000…..(2)
13z = 260000 …..(3)
Form (3) z = \(\frac{260000}{13}\)
Substituting z = ₹ 20000 in (2) we get
y + 40000 = 55000 = y ⇒ 55000 – 40000 = ₹ 15000
Substituting z = ₹ 20000, y = ₹ 15000 in (1) we get
x + 15000 + 20000 = 65000
x = 65000 – 35000 = ₹ 30000
So the amount invested in
6% bond x = ₹ 30000
8% bond y = ₹ 15000
and 10% bond z = ₹ 20000

(b) Find the equation of the curve whose slope is \(\frac{y-1}{x^{2}+x}\) and which passes through the point (1, 0).
Answer:

Question 42.
(a) If arg (z – 1) = \(\frac{\pi}{6}\) and arg (z + 1) = 2\(\frac{\pi}{3}\) , then prove that |z| = 1.
Answer:
Given arg (z-1) = \(\frac{\pi}{6}\) = 30° and arg (z + 1) = \(\frac{2 \pi}{3}\) = 120°
So, arg (z + 1) – arg (z – 1) = 120° – 30° = 90°
ie, ang \(\frac{z+1}{z-1}=90^{\circ}=\frac{\pi}{2}\)
\(\operatorname{Re} \frac{z+1}{z-1}=0\) [∴arg = \(\tan \theta=\frac{I P}{R P}\)

Therefore x= -1 and x=1 are vertical asymptotes.
The rough sketch of the curve is shown on the right side.

Question 43.
(a) Solve the equation x³ – 9x² + 14x + 24 = 0 if it is given that two of its roots are in the ratio 3:2.
Answer:
The given equation is x³ – 9x² +14x + 24 = 0…
Since, the two roots are in the ratio 3:2.
The roots are α , 3λ, 2λ
α + 3λ + 2λ = -b = 9
= a + 5λ = 9 (a) ….. (1)
α (3λ) (2λ) = -24
6λ²a = -24 => λ²α = -4 …….(2)
α = 9 – 5λ
λ² (9 – 52) = -4
9λ² – 5λ³ + 4 = 0
5λ³ – 9λ² – 4 = 0
(λ – 2) (5λ² + λ + 2) = 0
λ = 2,5λ² + λ+ 2 = 0 has only Imaginary roots ∆ < 0
∴ when λ = 2, α = 9-5 (2) = 9 – 10 = -1
∴ The roots are α, 3λ, 2λ i.e., -1, 6, 4

(b) Show that the lines \(\frac{x+3}{-3}=\frac{y-1}{1}=\frac{z-5}{5}\) and \(\frac{x+1}{-1}=\frac{y-2}{2}=\frac{z-5}{5}\)
are coplanar. Also -3 .. 1 5 -1 2 find the equation of the plane containing these two lines.
Answer:
From the lines we have,
(x₁, y₁, z₁) = (-3, 1, 5); (b₁, b₂, b₃) = (-3, 1, 5)
(x₂, y₂, z₂) = (-1, 2, 5); (d₁, d₂, d₃) = (-1, 2,5)
Conditions for coplanar

\(\left|\begin{array}{ccc}
2 & 1 & 0 \\
-3 & 1 & 5 \\
-1 & 2 & 5
\end{array}\right|\) = 2(5 – 10) – 1(-15 + 5) + ((-6 + 1) = -10 + 10 = 0
Given two lines are coplanar

(x + 3)(5 – 10) – (y – 1)[-15 + 5) + (2 – 5)(-6 + 1] = 0
5(x + 3) + 10(y – 1) – 5(z – 5) = 0
(÷ by -5) ⇒ (x + 3) – 2 (y – 1) + (z – 5) = 0
x + 3 – 2y + 2 + 2 – 5 = 0 .
or x – 2y + z = 0

(x + 1)(5 – 10) – (y – 2)(-15 + 5) + (z – 5)(-6 + 1) = 0
-5(x + 1) + 10(y – 2) – 5(2 – 5) = 0
(x + 1) – 2(y – 2) + (2 – 5) = 0
x + 1 – 2y + 4 + 2 – 5 = 0
x – 2y + z = 0

\end{array}\right.\)
Answer:
Observe that the given distribution is continuous

Question 46.
(a) Show that the equation of the normal to the curve x= a cos³θ, y = a sin³ θ at ‘θ’ is
x cos θ – y sin θ= a cos 2 θ.
Answer:
x = a cos³θ
\(\frac{d x}{d \theta}\) = a[ 3cos²θ](-sin θ) = -3acos²θ sin θ
y= a sin³θ

Slope of the normal = \(\frac{-1}{m}=\frac{\cos \theta}{\sin \theta}\)Point = (x1, yy) = (a cos³ θ , a sin³ θ ) sin θ
So, equation of the normal is
Y-a sin³ θ = \(\frac{\cos \theta}{\sin \theta}\)(x- a cos³ θ)
i.e. y sin θ – a sin⁴ θ = x cos θ – a cos⁴ θ
x cos θ – sin θ = a cos⁴ θ – a sin⁴ θ
i.e x cos θ – y sin θ = a [cos²θ+ sin²θ] [cos²θ – sin²θ]
= a [cos 2 θ]
So, the equation of the normal is x cos θ – y sin θ = a cos 2θ

(b) Verify (i) closure property (ii) commutative property (iii) associative property (iv) existence of identity and (v) existence of inverse for the operation +₅ on Z₅ using table corresponding to addition modulo 5.
Answer:
It is known that Z₅ = {[O], [1], [2], [3], [4]} . The table corresponding to addition modulo 5 is as follows: We take reminders {0,1,2,3,4} to represent the classes {[0],[1],[2],[3],[4]}.

(i) Since each box in the table is filled by exactly one element of Z₅, the output a +₅b is unique
and hence +₅ is a binary operation.

(ii) The entries are symmetrically placed with respect to the main diagonal. So +₅ has commutative
property.

(iii) The table cannot be used directly for the verification of the associative property. So it is to be verified as usual.
For instance, (2 +₅3) +₅ 4 = 0 +₅ 4 = 4 (mod 5)
and 2 +₅ (3 +₅ 4) = 2 +₅ 2 = 4 (mod 5). Hence (2 +₅3) +₅ 4 = 2 +₅ (3 +₅4).
Proceeding like this one can verify this for all possible triples and ultimately it can be shown that +₅ is associative.

(iv) The row headed by 0 and the column headed by 0 are identical. Hence the identity element is 0.

(v) The existence of inverse is guaranteed provided the identity O exists in each row and each column. From Table-A, it is clear that this property is true in this case. The method of finding the inverse of any one of the elements of Z₅ , say 2 is outlined below.

First find the position of the identity element 0 in the III row headed by 2. Move horizonta along the III row and after reaching 0, move vertically above 0 in the IV column, because 0 is in the III row and IV column. The element reached at the topmost position of IV column is 3. This element 3 is nothing but the inverse of 2, because, 2 +₅ 3 = 0 (mod 5). In this way, the inverse of each and every element of Z₅ can be obtained. Note that the inverse of 0 is 0, that of 1 is 4, that of 2 is 3, that of 3 is 2 , and that of 4 is 1.

Question 47.
(a) Identify the type of conic and find centre, foci, vertices, and directrices the following:
18x² + 12y² – 144x + 48y + 120 = 0
Answer:
18x² + 12y² – 144x + 48y + 120 = 0
(18x² – 144x) + (12y² + 48y) = -120
18(x² – 8x) + 12 ( 12 + 4y) = -120
18(x² – 8x + 16 – 16) + 12 (12+ 4y + 4 – 4) = -120
18(x – 4)² – 288 + 12(y + 2)² – 48 = -120
18(x – 4)² + 12(y + 2)² = -120 + 288 + 48 = 216

[OR]

(b) Prove that g(x, y) = x log \(\left(\frac{y}{x}\right)\) is homogeneous; what is the degree? Verify Euler’s Theorem for g.
Answer:
g (x, y) = x log(y/x)
8 (tx, ty) = (tx) log \(\left(\frac{t y}{t x}\right)\)
= txlog \(\left(\frac{y}{x}\right)\)
g(tx, ty) = t g(x, y)
∴ ‘g’is a homogeneous function of degree 1. By Euler’s theorem, we have

∴ Euler’s theorem verified.

Question 29.
Highlight the factors responsible for the all-women Indian Navy crew to carry out their expedition.
Answer:
The support the crew members received is a major factor. When they knew that they were doing well and looked after themselves well, in spite of all apprehensions they were supportive. The crew members personal aim and target mattered a lot. Mostly they wanted to make sure that they complete the journey with ultimate honesty without the use of engines. Than the destination, the journey was important. So their contention was to make sure that they go by the rules of circumnavigation without any means of repulsion and anybody else’s assistance.

The presence of mind and common sense to make decisions and act quickly was an added factor. They had to quickly do analyse problem solving techniques. Ego should never come amidst them. Team work helped them to collaborate and work together. Mutual understanding was important too. One would heat the water while the other would heat the gloves or even rested. Over all the confidence you have in each other than the trust and acceptance as every member of the crew to be a family is a must to carry out the expedition.

“It s about women helping women and women doing things
together and supporting each other. ”

Question 30.
Discuss the role played by Kim and Stephen Hawking to utilize technology for the disabled?
Answer:
Technology plays a vital role in transforming the lives of a disabled. Kim made them realize life isn’t tough because you are differently-abled. Kim made them realize that you can keep in touch with your family, you can talk to and even see relatives who live far away. Well, Kim has shown them that technology can do even more for young disabled people like me. It can make friends communicate and control the environment. It can help them study, get qualifications and find opportunities for work.

It can make them confident and independent. World renowned physicist Stephen Hawking is probably the best example of how assistive Technology has helped a talented mind overcome physical impairments and contribute productively to the world. So we can now look forward to a more inclusive way of learning, instead of the cloistered existence that most differently-abled learners had to face in the past. Newer technology allows differently-abled learners to learn with their peers as well as contribute fruitfully to the collaborative process of learning. This is indeed the new era of learning – truly a learning for all.

“Technology is not just a tool. It can give learners a voice
that they may not have had before.”

Question 31.
We appreciate the value of something only when we are about to lose it. Explain this with reference to the French language and M. Hamel.
Answer:
The Last Lesson’, written by Alphonse Daudet describes the year 1870 when the Prussian forces under Bismarck attacked and captured France. Alsace and Lorraine, districts of France went into Prussian hands. The new Prussian rulers issued an order that only German should be taught in all schools.

The French teachers were asked to leave with immediate effect. The story describes the last day of one such French class under M. Hamel. M. Hamel had taught French for forty years. Most of them never knew the value of the teacher’s devotion and dedicated service.

We do not always get an opportunity to learn, and this is never understood till the end. Luck doesn’t favour always. Likewise, opportunity knocks ones. Time should be valued. Procrastination is a sin. Most of us end up delaying things. Unless we are constant and regular in our efforts, we cannot achieve our goals. When things come easy, we do not realise its value.

Time and tide wait for no man. The entire village knew the value of Mr. Hamel and his teaching only when he was asked to leave. There was no use in their regrets. It was all too late. Therefore, let’s remember that we should make hay when the sun shines and not weep in vain.

“ Understand your worth; Value your life; Appreciate your blessings. ”

Question 32.
Give a brief character sketch of Sasanka Sanyal.
Answer:
Sasanka Sanyal was a wise and intelligent student. Perhaps luck never favoured him. He may have been a book-worm. However, he was overpowered by his friends because of his innocence. Hence, Aditya Narayan Chowdhury exploits him and takes away his Silver medal that he had received for Poetry Recitation. He had a wonderful memory power and could recall every single incident of his past.

He remembered Aditya when he saw him in Nagen’s Tea Cabin and confirmed his memory seeing his mole on the right cheek. He was rude in his behaviour towards Aditya as he did not want to suppress his feelings and vented out his anger on him. He was remorse after the death of his family members.

He whiled away his time at Nagen’s shop yet never gave up his self-respect and paid for the cup of coffee and biscuits if in case he had. Financially, he wasn’t comfortable since he couldn’t afford even a spectacle because of his partial deformity in his eye-sight.

“ Self-respect permeates every’ aspect of your life.”

Question 33.
How are today’s women portrayed by the poet in, ‘I Am Every Woman’?
Answer:
Rakhi Nariani Shirke is an academician with a passion for writing poems as a medium of self-expression. This poem talks about the multifaceted nature of women. A woman is born beautiful and beauty is an inborn trait. She is a symbol of supremacy and strength. She takes risks in life for she is real and always genuine. Today’s women are empowered, brave, strong and resolute.

They are always ready to take up new ventures. They are persistent and work tirelessly to prove what they are capable of. Women have to be treated respectfully for the growth of a nation. As stated earlier, she is the symbol of strength as she is strong in her faith and beliefs. In spite of all the out breaths and cries and laments, she is strong in her hope and firm in her trust. She is a lioness, brave and daring. She is a disciplinarian and will not tolerate your pranks with her. She is a woman of today to beware of.

“Each time a woman stands up for herself, she stands up for all women.”

Question 34.
Comment on the house located on Elm street.
Answer:
Nadia Bush brings out the eerie nature while reading her poem. The House On Elm Street.” There aren’t any houses around this house located on Elm Street. It stood all alone in an isolated place. Next to the house, is a tree. The tree too is mysterious like the house since no leaves sprout in any of the seasons. It is said to be a mysterious place since no one knows who lives there or what is inside. No one knows what happens inside that house and hence it is very mysterious. It is for sure a big house with vast space inside the house. Generally, at night, the house looks like it is alive with people in it.

Lights are switched on and off. Every day the poetess, drives past the house. The house seems to look a bit brighter on a fine warm summer day in the month of May. The very thought of this mysterious house plays with your mind since it is just one house of this kind in the areas known around. Likewise, the tree too is barren during winter, spring, summer and autumn. The poetess says that the tree just stays there and never grows tall nor becomes short. She wonders how a tree could survive without any leaves or without any growth and hence feels it is a mysterious place.

“The mystery’ of existence will always remain a mystery and secret.”

Question 35.

Question 36.
Paraphrase the following stanza.
But remember, please, the Law by which we live,
We are not built to comprehend a lie,
We can neither love nor pity nor forgive,
If you make a slip in handling us you die!
Answer:
In this stanza, the machines caution the readers with an unshakeable moral imperative – the Law by which it lives! The machines represent a form of absolute truth that is particularly difficult for mankind to understand. Here machines tell us that they don’t emote nor understand different feelings such as love, pity or apology. It reiterates its dangerous nature by simply stating that a slip while handling it means instant death.

Question 40.
Vivek has been asked to deliver a speech on ‘The Brain Drain Problem’. Use your own ideas, and write the speech in about 150-200 words.
Answer:
Respected Principal, teachers and dear friends!
Good morning to one and all present here. I, Vivek of Std. X, am thankful to the teachers for giving me this opportunity.

The problem of brain-drain has assumed serious proportion in the last thirty years or so. The nation spends its hard-earned meagre resources on the education and training of its doctors, engineers, scientists, etc. But these highly talented and trained men and women of genius migrate to developed countries.

They desert the ranks for the lure of money, better facilities and living conditions. Some of them get opportunities for fulfilment of their ambitions and development of personality as there is full scope for it. They enjoy unlimited freedom for experiments and research and fear no resources crunch.

The parent countries become poorer by the depletion of resources as a result of migration of trained and talented persons. The migrants too feel maladjusted in the new country where they are considered second grade citizens. Living and working in an alien culture among foreigners, they find themselves cut off from their own social modes and customs. They do suffer emotional vacuum as the memories of friends and relatives in their country haunt their minds.

India too has been facing this problem. We must take steps to ensure them better facilities, improved living conditions, freedom for experimentation and research. In addition to this, their talents must be utilised for proper work and their work must be given due recognition. These measures, if adopted seriously, can check the problem effectively.
Thank you.

Question 43.
Make notes or write a summary of the following passage.
Answer:
When we survey our lives and efforts we soon observe that almost the whole of our actions and desires are bound up with the existence of other human beings. We notice that whole nature resembles that of the social animals. We eat food that others have produced, wear clothes that others have made, live in houses that others have built.

The greater part of our knowledge and beliefs has been passed on to us by other people though the medium of a language which others have created. Without language and mental capacities, we would have been poor indeed comparable to higher animals. We have, therefore, to admit that we owe our principal knowledge over the least to the fact of living in human society.

The individual if left alone from birth would remain primitive and beast like in his thoughts and feelings to a degree that we can hardly imagine. The individual is what he is and has the significance that he has, not much in virtue of the individuality, but rather as a member of a great human community, which directs his material and spiritual existence from the cradle to grave.

Being social animals, human beings have their actions and desires bound up with society. In matter of food, clothes knowledge and belief they are interdependent with one another. We eat food that others have produced clothes that others have made, live in houses that others have built. They use language created by others without language their mental power would not grow.

Question 46.
Write a paragraph of about 150 words by developing the following hints. [2 x 8 = 16]
(a) Prospero a sympathetic character – uses magic to control – learns sorcery – protects Miranda – control Ariel and others – alter weather – raise the dead – demands attention – an insensitive character to compassionate character – rightful duke of Milan – humanity in his treatment of Antonio – extremely forgiving – helpless against his enemies – white magic and not black magic – complex personality – refuses to free Ariel – subjugates Caliban – ruler appears insensitive and harsh – tyrannical – understanding – protective just and fair, intelligent.
Answer:
In ‘The Tempest’ by William Shakespeare, Prospero is the main character yet a sympathetic character. You could also say he isn’t very sympathetic because he uses magic to control other people. He has learned sorcery from books, and uses it while on the island to protect Miranda and control the other characters. Prospero’s sorcery is sufficiently powerful to control Ariel and other spirits, as well as to alter weather and even raise the dead.

Prospero insists that others listen to him even when they do not want to. His character grows from being an insensitive character to a much more compassionate and likable character with positive characteristics. Prospero is the rightful duke of Milan who is usurped by his brother. Prospero’s humanity is clearly obvious in his treatment of Antonio.

In spite of him being a traitor, he is extremely forgiving in nature. He is helpless against his enemies and wait for them to come close to his island so that he can use his magic to create a storm and bring them under his control. Prospero’s magic is the white magic of nature and not the black magic of evil nature. He is surely a complex personality.

Although he refuses to free Ariel and subjugates Caliban, Prospero is really a generous ruler, never intending to harm even his enemies. At first, Prospero appears insensitive and harsh, especially in his treatment of Ariel and Caliban. He is seen as tyrannical in his treatment of Ferdinand, but Prospero realizes that Ferdinand and
Miranda will value one another more if there are a few obstacles to their wooing. Prospero is protective of those who are close to him especially Miranda. Throughout, Prospero makes sure Ferdinand’s and Miranda’s love stays strong. Ultimately, we see Prospero to be just and fair besides being intelligent.

(b) Describe the farmer’s painful journey up the mountain by developing the given hints. A mother’s affection – insightful sustenance of sacrifice and pain – eternal and unconditional love is invaluable – the law – tyrant ruler – changes decision – a kind mode of death – summit of Obatsayuma – Her heart is concerned.
Answer:
The story of the Aged Mother, a folklore from Japan, tells a story about the care and wisdom of a mother to his son, their condition and the son’s love and gentle respect. This story talks about the conflict in the poor farmer’s mind.
A mother’s affection is something that none can describe. It is composed of insightful sustenance of sacrifice and pain which is eternal and unconditional.

The thought that “A mother’s love is invaluable and can never be equated to further belongings that a child might own’ perturbs the narrator. The law pronounced by the tyrant ruler fills the heart of the poor farmer with deep remorse. Instead of putting his mother to death in the hand of the cruel law he decides to give his mother a kind mode of death. He takes his mother to the bare summit of Obatsayuma and plans to abandon her there.

The mother too is pained on the way to the summit of the mountain. Her heart grows concerned because she knows that her son will be in danger on his way back because he is not familiar to the paths and hence she breaks the twigs and drops it quietly on the road to serve as a guide for her son’s return journey.

Question 47.
Read the following passage and answer the questions given below:
Answer:
In Titanic the ‘older’ Rose throws the Heart of the Ocean diamond over the side of the ship. While the Heart of the Ocean is only a fairy tale, it is based on the Hope Diamond or The Blue Fire. It was bought in India by a French jeweller in the 1660s and brought back to France.

The Blue Beauty was sold to Louis XIV where it began to attract a reputation as a cursed creature. Things did not end well with Louis XIV who was flat broke at the end of his life and who was eaten by a pack of wild dogs. It then passed on to Queen Marie Antoinette who was eventually beheaded. The diamond disappeared for two decades and eventually resurfaced amidst a story of suicides.

The last owner’s brother died early, her son was run over by a car when he was nine years old, she got divorced, her husband perished in a mental institution, her daughter died of an overdose and she herself died of pneumonia.
The Hope Diamond is now housed in the Smithsonian Institution in Washington.

Questions.
(a) Where did The Blue Fire originate?
(b) To whom was the Blue Beauty passed on after Louis XIV was dead?
(c) How did the diamond affect Louis XIV?
(d) Under what circumstances did the Hope Diamond resurface after two decades?
Ans.
(a) The Hope Diamond or The Blue Fire was bought in India originally by a French jeweller in the 1660s and taken back to France.
(b) The Blue Beauty was passed on to Queen Marie Antoinette who was eventually beheaded.
(c) When the diamond, Blue Beauty was sold to Louis XIV, things did not end well with him as he was flat broke at the end of his life and was eaten by a pack of wild dogs.
(d) The diamond disappeared for two decades and eventually resurfaced amidst a story of suicides.

PIPING DOWN THE VALLEYS

Piping down the valleys wild,
Piping songs of pleasant glee,
On a cloud, I saw a child,
And he laughing said to me :

“Pipe a song about a Lamb !”
So I piped with merry cheer.
“Piper, a pipe that song again;”
So I piped: he wept to hear.

Drop thy pipe, thy happy pipe;
“Sing thy songs of happy cheer.”
So I sang the same again,
While he wept with joy to hear.

“Piper, sit thee down and write
In a book, that all may read.”
So he vanish’d from my sight,
And I pluck’d a hollow reed,

And I made a rural pen,
And I stain’d the water clear,
And I wrote my happy songs
Every child may joy to hear.

Questions.
(a) Whom did the piper see in a cloud?
(b) What did the child ask the piper to do?
(c) When did the piper pluck a hollow reed?
(d) What did the child do after singing?
Answer:

Tamilnadu Samacheer Kalvi 12th Maths Solutions Chapter 7 Applications of Differential Calculus Ex 7.6

Question 1.
Find the absolute extrema of the following functions on the given closed interval.
(i) f(x) = x³ – 12x + 10; [1, 2]
(ii) f(x) = 3x⁴ – 4x³ ; [-1, 2]

Solution:

∴ Absolute maximum is – 1 and absolute minimum is – 6

(ii) f(x) = 3x⁴ – 4x³
f'(x) = 12x³ – 12x²
f'(x) = 0 ⇒ 12x²(x – 1) = 0
⇒ x = 0 or x = 1
[Here x = 0, 1 ∈ [-1, 2]]
Now f (-1) = 4
f(0) = 0
f(1) = -1
f(2) = 16
so absolute maximum = 16 and absolute minimum = -1

(iii)

(iv) f(x) = 2 cos x + sin 2x
f'(x) = -2 sin x + 2 cos 2x
f'(x) = 0 ⇒ cos 2x = sin x

Question 2.
Find the intervals of monotonicities and hence find the local extremum for the following functions

Solution:
(i) f(x) = 2x³ + 3x² – 12x
f'(x) = 6x² + 6x – 12
f'(x) = 0 ⇒ 6(x² + x – 2) = 0
(i.e.,) 6(x + 2)(x – 1) = 0
⇒ x = -2 or 1
Taking the points in the number line

The intervals are (-∞, -2), (-2, 1), (1, ∞)
when x ∈ (-∞, -2), f'(x) = 6 (-1) (-4) = +ve
say x = – 3
⇒ f(x) is strictly increasing in the interval (-∞, -2) when x ∈ (-2, 1), f’ (x) = 6 (2) (-1) = -ve
say x = 0
⇒ f(x) is strictly decreasing in the interval (-2, 1)
when x ∈ (1, ∞), f'(x) = 6 (4) (+1) = + ve say x = 2
⇒ f(x) is strictly increasing in (1, ∞)
Since f(x) changes from +ve to – ve when passing through -2, the first derivative, test tells us there is a local maximum at x = -2 and the local maximum value is f(-2) = 20.
Again f'(x) changes from – ve to +ve when passing through 1 ⇒ there is a local minimum at x = 1 and the local minimum value is f( 1) = -7. So (1 )f(x) is strictly increasing on (-∞, -2) and (1, ∞). And (2)f(x) is strictly decreasing on (-2, 1)
The local maximum = 20 and the local minimum = -7

f(x) is strictly decreasing on (-∞, 5) and (5, ∞)
And there is no local extremum
(iii)

For all x values, so f(x) is strictly increasing in (-∞, ∞) and there is no local extremum.

⇒ f(x) is strictly decreasing in (0, 1)

say x = 2
⇒ f(x) is strictly increasing in (1, ∞)
since f'(x) changes from -ve to +ve at x = 1, there is a local minimum at x = 1 and the local minimum values is f(1) = \(\frac{1}{3}-0=\frac{1}{3}\)
So the function is strictly decreasing on (0, 1) and strictly increasing on (1, ∞) and the local minimum value is \(\frac{1}{3}\)

Find the absolute maximum and absolute minimum values of f on the given interval.

Question 1.
f(x) = 1 – 2x – x², [-4, 1]
Solution:
f(x) = 1 – 2x – x²
f'(x) = -2 – 2x
f'(x) = 0 ⇒ 2x = -2 ⇒ x = -1; The points are -4, -1, 1
At x = -4, f(x) = 1 – 2(-4) – (-4)² = 1 + 8 – 16 = -7
At x = -1, f(x) = 1 – 2 (-1) – (-1)² = 1 + 2 – 1 = 2
At x = 1, f(x) = 1 – 2 (1) – (1)² = 1 – 2 – 1 = – 2
Therefore, the absolute minimum is -7 and the absolute maximum is 2.

Question 2.
f(x) = x³ – 12x + 1, [-3, 5]
Solution:
f(x) = x³ – 12x + 1
f'(x) = 3x² – 12
f'(x) = 0 ⇒ 3x² – 12 = 0
3x² = 12 ⇒ x² = 4 ⇒ x = ±2
The x values are -3, -2, 2, 5
f(x) (at x = -3) = (-3)³ – 12 (-3) + 1 = -27 + 36 + 1 = 10
f(x) (at x = -2) = (-2)³ – (12)(-2) + 1 = -8 + 24 + 1 = 17
f(x) (at x = 2) = 2³ – 12 (2) + 1 = 8 – 24 + 1 = -15
f(x) (at x = 5) = 53 – 12 (5) + 1 = 125 – 60 + 1 = 66
From the above four values 10,17,-15 and 66, we see that absolute maximum is 66 and the absolute minimum is -15.

Question 3.

Solution:

So, the absolute maximum is \(\frac{2}{3}\) and the absolute minimum is \(\frac{1}{2}\)

Question 4.
f(x) = sin x + cos x, [0, π/3]
f'(x) = sin x + cos x
f'(x) = cos x – sin x
f’ (x) = 0 ⇒ cos x – sin x = 0

Question 5.
f(x) = x – 2 cos x, [-π, π]
Solution:
f(x) = x – 2 cos x
f'(x) = 1 + 2 sin x
f'(x) = 0 ⇒ 1 + 2 sin x = 0

From the above values, absolute maximum is π + 2 and the absolute minimum is \(\frac{-\pi}{6}-\sqrt{3}\)

From the local maximum and minimum values of the following functions.

Question 6.
2x³ + 5 x² – 4x
Solution:

Local maximum = 12

Question 7.
t + cos t
Solution:

t = \(\frac{\pi}{2}\) is neither a maximum point nor a minimum point. So there is no maximum or minimum.

IV. Explain in detail

Question 1.
Differentiate Open Source Software with free software?
Answer:
Open-Source Software vs. Free Software:
Although the terms are often used interchangeably, OSS is slightly different from free software. Both deal with the ability to download and modify software without restriction or charge.

However, free software a concept developed in the 1980s by an MIT computer science researcher, Richard Stallman is defined by four conditions, as outlined by the nonprofit Free Software Foundation. These “four freedoms” emphasize the ability of users to use and enjoy software as they see fit.

In contrast, the OSS criteria, which the Open Source Initiative developed a decade later, place more emphasis on the modification of software, and the consequences of altering source code, licensing, and distribution.

Obviously, the two overlap; some would say the differences between OSS and free software are more philosophical than practical. However, neither should be confused with freeware. Freeware usually refers to proprietary software that users can download at no cost, but whose source code cannot be changed.

Question 2.
Explain Network Simulation Tool – NS2 in detail?
Answer:
Network simulation tool – NS2:

• In computer network, network simulation is a method whereby a software program , models the activities of a network by calculating the communication between the different
  network objects such as(routers, nodes, switches, access points, links etc.).
• A network simulator is a software program that replicates the functioning of a computer network.
• In simulators, the computer network is typically demonstrated with devices, traffic etc. and the performance are evaluated.
• Normally, users can then adapt the simulator to accomplish their precise analysis needs. The network parameters define the state of the network (node placement, existing links) and the events (data transmissions, link failures, etc.).
• A significant output of simulation is the trace files. Trace files can document every incident that happened in the simulation and are used for examination.
• NS2 is the abbreviation of NETWORK SIMULATOR version 2. It was considered explicitly for exploration in network communication and event-driven open-source simulator in computer.
• OTCL and C++ used to create and run NS2. NS2 works on Windows and Linux platforms, that supports wired or wireless network and also use the command line interface as a user interface, API a pure event base software tool with super simulation design, it has more models which help the user to get desired output easily.

Question 3.
Explain in Detail Open NMS?
Answer:

Question 2.
Discuss about OSI model with its layers?
Answer:
OSI Model:
Open System Interconnection (OSI) model was found in the year 1934, general framework that enables network protocols along with software and systems to be developed based on general set of guidelines. It describes the standards for the inter-computer communication.

OSI Layers:
(i) Physical Layer:
This is the 1st layer, it defines the electrical and physical specifications for devices.

(ii) Data Link Layer:
It is the 2nd layer and it guarantees that the data trAnswer:mitted are free of errors. This layer has simple protocols like “802.3 for Ethernet” and “802.11 for Wi-Fi”.

(iii) Network Layer:
It is the 3rd layer determining the path of the data packets. At this layer, routing of data packets is found using IP Addressing.

(iv) Transport Layer:
It is the 4th layer that guarantees the trAnswer:portation/sending of data is successful. It includes the error checking operation.

(v) Session Layer:
It is the 5th layer, identifies the established system session between different network entities. It controls dialogues between computers. For instance, while accessing a system remotely, session is created between your computer and the remote system.

(vi) Presentation Layer:
It is the 6th layer that does the trAnswer:lation of data to the next layer (Prepare the data to the Application Layer). Encryption and decryption protocols occur in this layer such as, Secure Socket Layer (SSL).

(vii) Application Layer:
It is the 7th layer, which acts as the user interface platform comprising of software within the system.

Question 3.

6. Rapid developments in cloud technologies.

Demerits of Mobile Networks:

1. Cost
2. Vulnerable to security risks.
3. Additional training is needed to use new technology.
4. Cyber crime

Development:
The generations of mobile networks are as follows.

1. First Generation(lG) 1981- NMT launch
2. Second Generation(2G) 1991-GSM Launch
3. Second to Third Generation Bridge (2.5)2000 – GPRS launch
4. Third Generation! 3G) 2003- first UK 3G launch
5. Fourth Generation (4G) 2007
6. Fifth Generation (5G) 2019+

1. First Generation (1G) 1981 – NMT launch:

1. During the initial periods the mobile systems were based on analog trAnswer:mission.
2. NMT stands for Nordic Mobile Telephone communication.
3. And a very poor voice quality.

2. Second Generation(2G) 1991-GSM Launch:

1. Later the second generation of mobile systems were placed on digital trAnswer:mission with GSM.
2. GSM stands for (Global System for Mobile communication) was most popular standard which is used in second generation, using 900MHz and 1800MHz for the frequency bands.
3. The transfer mission used as TMDA stands for (Time Division Multiple Access) and CDMA One stands for (Code Division Multiple’Access) method to increase the amount of information trAnswer:ported on the network

3. Second to Third Generation Bridge (2.5)2000 – GPRS launch:

1. GPRS was introduced here GPRS stands for (General Packet Radio Service). GPRS is a data service which enables mobile devices to send and receive messages, picture messages and e-mails.
2. GSM data transfer mission rates typically reached 9.6kbit/s.

4. Third Generation( 3G) 2003- first UK 3G launch:
1. This generation of mobile systems merges different mobile technology standards, and uses higher frequency bands for transfer mission and Code Division Multiple Access to delivery data rates of up to 2Mbit/s supports multimedia services (MMS: voice, video and data).

2. Data transfer mission used a WCDMA. WCDMA stands for (Wideband Code Division Multiple Access).

3. Few 3G suppliers use ATM (Asynchronous Transfer Mode) for their ‘over the air’ network with in MPLS (Multiprotocol Label Switching) or IP for theirs backbone network.

5. Fourth Generation (4G) 2007:

1. 4G is at the research stage. 4G was based on an adhoc networking model where there was no need for a fixed infrastructure operation.

2. Adhoc networking requires global mobility features (e.g. Mobile IP) and connectivity to a global IPv6 network to support an IP address for each mobile device.

3. Logically roaming in assorted IP networks (for example: 802.11 WLAN, GPRS and UMTS) were be possible with higher data rates, from 2Mbit/s to 10-100Mbit/s, offering reduced delays and newly services.

6. Fifth Generation (5G) 2019+:

1. 5G is the stage succeeds the 4G (LTE/ WiMAx), 3G(umts) and 2G(GSM) syetems.

2. 5G targets to performance the high data rate, reduced latency, energy saving, cost reduction, higher system, capacity, and massive device connectivity.

3. The ITU IMT – 2020 provides speeds up to 20 gigabits per second it has been demonstrated with millimeter waves of 15 gigahertz and higher frequency.

Question 3.
Discuss in detail about TCP/IP protocols?
Answer:
TCP/IP:
Transmission Control Protocol/Internet Protocol, TCP/IP is a set of protocols which governs communications among all computers on the Internet. TCP/IP protocol tells how information should be packaged, sent, and received, as well as how to get to its destination.

TCP WORKING: TCP/IP is a combination of two protocols: TrAnswer:mission Control Protocol (TCP) and Internet Protocol (IP). The Internet Protocol typically specifies he logistics of the packets that are sent out over networks; it specifies the packets which have to go, where to go and how to get there. The TrAnswer:mission Control Protocol is accountable for guaranteeing the trustworthy trAnswer:mission of data. It sees that the packets for errors and submits the requests for re-trAnswer:missions incase any of them are missing’.

Frequent TCP/IP Protocols

• HTTP – It is used between a web client and a web server and it guarantees non-secure data trAnswer:missions.
• HTTPS – It is used between a web client and a web server ensures secure data trAnswer:missions.
• FTP – It is used between computers for sending and receiving file.

Domain Names and TCP/IP Addresses
The address for any website is not as easy as to remember, domain name are used instead. For example, 216.58.216.164 is one of the IP address for Google and google.com is the domain name.

The Different Layers of TCP/IP
There are four total layers of TCP/IP protocol, each of which is listed below with a brief description.

1. Network Access Layer – concerned with building packets.
2. Internet Layer – describes how packets are to be delivered.
3. Transport Layer – ensure the proper transmission of data.
4. Application Layer – application network processes. These processes include File Transfer Protocol (FTP), Hypertext TrAnswer:fer Protocol (HTTP), and Simple Mail Transfer Protocol (SMTP).

Question 4.
Explain the important protocols present in

1. Network layer
2. Transport Layer

Answer:
1. Network Layer:
It is the layer where data is addressed, packaged, and routed among networks. The important Internet protocols that operate at the Network layer are:

2. Internet Protocol (IP):
Routable protocol which uses IP addresses to deliver packets. It is an unreliable protocol, does not guarantee delivery of information.

3. Address Resolution Protocol (ARP):
Resolves IP addresses to MAC (Medium Access Control) addresses. (A MAC address is a hardware identification number that uniquely identifies each device on a network.)i.e., to map IP network addresses to the hardware addresses.

4. Internet Control Message Protocol (ICMP):
Used by network devices to send error messages and operational information. Example: A host or router might not be reached or a requested service is not presented.

5. Internet Group Management Protocol (IGMP):
It is a communication protocol used by hosts and routers to send Multicast (group Communication) messages to multiple IP addresses at once.

6. port Layer:
The sessions are recognized and data packets are swapped between hosts in this layer. Two main protocols established at this layer are:

7. Mission Control Protocol (TCP):
Provides reliable connection oriented trAnswer:mission between two hosts. It ensures delivery of packets between the hosts.

8. User Datagram Protocol (UDP):
Provides connectionless, unreliable, one-to-one or one- to-many delivery.

PART – IV
IV. Explain in detail

Question 1.
What is meant by Registered Jack? Explain briefly the types of Jacks?
Answer:
Types of JacksRegistered Jacks:
A Registered Jack commonly known as RJ is a network interface used for network cabling, wiring and jack construction. The primary function of the registered jack is to connect different data equipment and telecommunication devices.

The commonly known registered jacks are RJ-11, RJ-45, RJ-21, and RJ-28. The registered jack refers to the male physical connector (Plug), a female physical connector (Jack) and it’s wiring. We will talk some of the variety of registered jack below with some defintions.

It is the most popular modem form of registered j ack. It is found in home and office. This registered jack is mainly used in telephone and landlines. When we look the pin details of the RJ-11, there are 6 pin where the two pins give the transmission configuration, the two pins give the receiver configuration and the other two pins will be kept for reserved. The two pin will have the positive terminal and the negative terminal.

RJ-14 and RJ-61:
The RJ-14 is the same as RJ-11 which will be used for telephone lines where same it as 6 pins whereas the RJ-61 will have 8 pins. This RJ-61 will use the twisted pair cable with a modular 8 connection.

RJ-21:
The RJ-21 connector has 50 pins with 25 pins at one end and 25 pins at the other end. It is also called as champ connector or Amphenol connector. The Amphenol is a connector manufacturer. The RJ-21 interface is typically used for data communication trucking applications.

Question 2.
Explain wiring techniques used in Ethernet cabling?
Answer:
There are three types of wiring techniques to construct the Ethernet cable. It is also known as color coding techniques. They are:

1. Straight-Through Wiring
2. Cross-over Wiring
3. Roll-over Wiring Straight-Through Wiring

In general, the Ethernet cables used for Ethernet connections are “straight-through cables”. These cable wires are in the same sequence at both ends of the cable, which means that pin 1 of the plug on one end is connected to pin 1 of the plug on the other end (for both standard – T568A & T568B). the straight through wiring cables are mostly used for connecting PC / NIC card to a hub. This is a simple physical connection used in printers, computers and other network interfaces.

Cross-over Wiring:
If you require a cable to connect two computers or Ethernet devices directly together without a hub, then you will need to use a Crossover cable instead. Then the pairs(Tx and Rx lines) will be crossed which means pin 1 & 2 of the plug on one end are connected with pin 3 & 6 of the plug on other end, and vice versa (3 & 6 to pin 1 & 2).

The easiest way to make a crossover cable is to make one end to T568A colour coding and the other end to T568B. Another way to make the cable is to remember the colour coding used in this type. Here Green set of wires at one end are connected with the Orange set of wires at another end and vice versa. Specifically, connect the solid Green (G) with the solid Orange, and connect the green/white with the orange/white.

Roll-over WiringRollover cable is a type of null-modem cable that is often used to connect a device console port to make programming changes to the device. The roll over wiring have opposite pin arrangements, all the cables are rolled over to different arrangements.

In the rollover cable, The coloured wires are reversed on other end i.e. The pins on one end are connected with other end in reverse order (i.e. pin 1 to 8, 2 to 7, 3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, 8 to 1). Rollover cable is also known as Yost cable or Console cable. It is typically flat (and light blue color) to distinguish it from other types of network cabling.

These all the three arrangements are used to perform an interface change. But, all the three arrangements transmits the data at the same speed only.

Question 3.
Explain about RJ45 connector?
Answer:

1. The RJ45 connector is a small plastic cup which will be used to connect the wire inside the connector and ready to connect the Internet.
2. The RJ45 connector looks similar like a telephone jack but it looks a slightly wider.
3. The Ethernet cables are sometime called as RJ45 cables.
4. In RJ45 the “RJ” stands for the Registered Jack and the “45” simply refers to the number of interface standard in the cable.
5. Each RJ45 connector has eight pins and connected to each end of the Ethernet cable.
6. Since it has 8-position, 8-contact (8P8C) modular plug, It is also known as 8P8C connector.

The two main signals of the pins: the one is the TX which is transmission of data and RX
which is Receiver of data.
“In the Figure the position of pin no. 1 describes the transmit data or bidirectional, the bidirectional means it can be sent to both connection with the TX (positive). The TX+ has positive terminal and the color is used in this position is white green.

• In the position of pin no. 2 describes the transmit data or bidirectional with the TX (negative). The TX- has negative terminal and the color is used in this position is Green.
• In the position of pin no.
• Describes the receive data or bidirectional with the RX (positive). The RX is compatible to receive the data which has positive terminal and the color is used in this position is white orange.
• In this position of pin no. 4 describes that it is not connected or bidirectional. It means there will be no transmitting or receiving will exist. But it can be used later for some other connection. The color used in this pin is blue.

• In this position of pin no. 5 describes that it is not connected or bidirectional and the color is white blue.
• In this position of pin no. 6 describes the receive data or bidirectional with the RX (Negative) which has a negative terminal and the color used in this position is orange.
• In this position of pin no. 7 describes that it is not connected or bidirectional and the color is white brown.
  In this position of pin no. 8 describes that it is not connected or bidirectional and the color is brown.

Question 4.

Answer:
The main components are used in the Ethernet cabling are

1. Patch Cable (Twisted pair)
2. RJ45 Connector
3. Ethernet Ports
4. Crimping Tool

1. Patch Cable (Twisted Pair):
1. These Cables are generally made up of 8 wires in different colors.

2. Four of them are solid colours, and the others are striped.
3. The eight colors are white green, green, white orange, blue, white blue, orange, white brown and brown. The following figure 13.8 shows the patch cable.
Ethernet cables are normally manufactured in several industrial standards such as Cat 3, Cat 5, Cat 6, Cat 6e and cat 7. “Cat” simply stands for “Category,”. Increasing the size of the cable also lead to slower transmission speed.

4. The cables together with male connectors (RJ45) on each end are commonly referred as Ethernet cables. It is also called as RJ45 cables, since Ethernet cable uses RJ45 connectors.

2. RJ45 Connector:

• The RJ45 connector is a small plastic cup which will be used to connect the wire inside the connector and ready to connect the Internet.
• The RJ45 connector looks similar like a telephone jack but it looks a slightly wider.
• The Ethernet cables are sometime called as RJ45 cables.
• In RJ45 the “RJ” stands for the Registered Jack and the “45” simply refers to the number of interface standard in the cable.
• Each RJ45 connector has eight pins and connected to each end of the Ethernet cable.
• Since it has 8-position, 8-contact (8P8C) modular plug, It is also known as 8P8C connector. Th£se plugs (connector) are then inserted into Ethernet port of the network card.

3. Ethernet card and Port:

• Ethernet card is a Network Interface Card (NIC) that allows computers to connect and transmit data to the devices on the network. It may be an expansion card or built-in type.
• Expansion card is a separate circuit board also called as PCI Ethernet card which is inserted into PCI slot on motherboard of a computer.
• Now a days most of the computers come with built-in Ethernet cards which resides on motherboard.
• Wireless Ethernet cards are also available, which uses radio waves to transmit data.
• Ethernet port is an opening which is a part of an Ethernet card. It accepts RJ45 connector with Ethernet cable. It is also called as RJ45 jack. It is found on personal computers, laptops, routers, switches, hubs and modems.
• In these days, most of the computers and laptops have a built-in Ethernet port for connecting the device to a wired network.

4. Crimping Tool:

• Crimping is the process of joining two or more pieces of metal or wire by deforming one or both of them to hold each other.
• The crimping tool is a physical tool which is used to connect the patch wire and the Ethernet connector.
• The tool will puncture the connector and makes the wire set in the connector.

Question 5.
Explain the types of network cables?
Answer:
There are many types of cables available in the networking.

1. Coaxial Cables:
Ths cable was invented at late 1880’s, which is used to connect the television sets to home antennas. Ths cable is used to transfer the information in 10 mbps. The cable is divided into thin.net and thicknet cables. These cables have a copper wire inside and insulation is covered on the top of the copper wire to provide protection to the cable.

These cables are very difficult to install and maintain, because they are too big to carry and replace. The coaxial cable got its name by the word “coax”. Nowadays coaxial cables are also used for dish TV where the setup box and the television is connected using the coaxial cable only. Some of the cable names are Media Bridge 50-feet Coaxial cable, Amazon basics CL2-Rated Coaxial cables, etc.

2. Twisted Pair Cables:
It is type of cable with two or more insulated wires twisted together. It started with the speed of 10 mbps (10BASE-T cable is used). Then the cable is improved ” and the speed was higher and went to 100 mbps and the cable-was renamed as 100BASE-TX. Then finally the cable improved more made to 10 gbps and named as 10GBASE-T. Ths twisted cable has 8 wires which are twisted to ignore electromagnetic interference.

Also the eight wires cannot be placed in a single unit there could be a difficult in spacious, so it is twisted to make as one wire. There are two types of twisted pair cables, Unshielded Twisted Pair (UTP) and Shielded Twisted pair (STP). The UTP is used nowadays as modem cables for Internet and they are lower in cost and installation and maintenance is easy compared to the coaxial cables. STP is similar to UTP, but it is covered by an additional jackets to protect the wires from External interference.

3. Fiber Optics:
This cable is different from the other two cables. The other two cables had an insulating material at the outside and the conducting material like copper inside. But in this cable it is of strands of glass and pulse of light is used to send the information. They are mainly used in Wide Area Network (WAN). The WAN is a network that extends to very large distance to connect the computers. One example of WAN is Internet.

These cables are placed in deep underground to avoid any damage to the cables. The optic cable uses light to transmit the information from one place to another. There are two types of fiber optic cables available, One is single-mode (lOOBaseBx) another one is Multimode (lOOBaseSX). Single-mode cables are used for long distance transmission and at a high cost whereas the multimode cables are used for short distance transmission at a very low cost. The optic cables are easy to maintain and install.

4. USB Cables:
The Universal Serial Bus are used to connect keyboard, mouse and other peripheral devices. But there are some special network devices used to connect the Internet through the USB called dongles. The dongle is a small peripheral device which has a compatible of mobile broadband with a sim slot in it and connects the Internet and acts as a modem to the computer.

5. Serial and Parallel cables:
Before In the year of 1980s to 1990s the Ethernet and the USB were not developed. Then the Serial and Parallel interface cables are used to connect the Internet to the system. They were sometime used for PC to PC networking. Before the USB emerged, the system will have both serial port and parallel port.

The serial port will send 1 bit at one time whereas the parallel port will send 8 bit at one time. The parallel cables are used to connect to the printer and other disk drivers. RS232 is one type of serial cable, also known as Null modem cable.

6. Ethernet Cables:
Ethernet cable is the most common type of network cable mainly used for connecting the computers or devices at home or office. This cable connects wired devices within the local area network (LAN) for sharing the resources and accessing Internet.

Question 11.
Write note on straight-through wiring?
Answer:
In general, the Ethernet cables used for Ethernet connections are “straight-through cables”. These cable wires are in the same sequence at both ends of the cable, which means that pin 1 of the plug on one end is connected to pin 1 of the plug on the other end (for both standard – T568A & T568B). the straight through wiring cables are mostly used for connecting PC / NIC card to a hub.

IV. Explain in detail

Question 1.
Explain the Crimping process to make Ethernet cables?
Answer:
Crimping process for making Ethernet cables

1. Cut the cable with desired length
2. Strip the insulation sheath about 1 inch from both end of the cable and expose the Twisted pair wires
3. After stripping the wire, untwist the smaller wires and arrange them into the proper wiring scheme, T568B preferred generally.
4. Bring the wires tighter together and cut them down so that they all have the same length ( Vi inch).
5. Insert the all 8 coloured wires into the eight grooves in the connector. The wires should be, inserted until the plastic sheath is also inside the connector.
6. Use the crimping tool to lock the RJ45 connector on the cable. It should be strong enough to handle manual traction. Now it is ready for data transmission.
7. Use a cable tester to verify the proper connectivity of the cable, if need.
