Question 2.
Explain Tyndall effect and Brownian movement with suitable diagram.
A. Tyndall Effect:

When a strong beam of light is focused on a colloidal solution the path of the beam becomes visible.
This phenomenon is called as Tyndall effect. The illuminated path is called Tyndall cone. This phenomenon is due to scattering of light by colloidal particles.

B. Brownian movement:

It is a kinetic property. When colloidal solution are viewed under powerful microscope, it can be seen that colloidal particles are moving constantly and rapidly in zig-zag directions. The Brownian movement of particles is due to the unbalanced bombardment of the particles by the molecules of dispersion medium.

Question 3.
How is a mixture of common salt, oil and water separated?
You can use a combination of different methods.
Answer:
The mixture of common salt, oil and water are taken in a beaker. The salt dissolves in water. Allow it to stand for a few minutes. The mixture of two immiscible liquids is separated by a separating funnel. The oil floats on top. The water can carefully be separated by opening the stopcock in the separating funnel. The oil is left behind in the separating funnel.

The salt water is heated slowly, in a distillation flask with a water condenser. The pure water vapour passes through the inner tube of the condenser.

The vapours on cooling condense into pure water and are collected in a receiver. The salt is left behind in the flask as a residue.

Question 2.
In a hydraulic lift, the surface area of the input piston is 10 cm². The surface area of the output piston is 3000 cm². A 100 N force applied to the input piston raises the output piston. Calculate the force required to raise the output piston.
Answer:
Solution:
Pressure input on piston,

According to Pascal’s law
P =\(\frac { F }{ A}\)
P = \(\frac { F}{ A }\)
10⁵ = \(\frac { F }{ 3000 x 10^-4}\) = \(\frac { F x 10^-4}{ 3000 }\)
l0^-4 x F = 10⁵ x 30OO
F = 3000×10¹
= 3 x 10⁴ N

Pascal’s law.

Question 4.
What do you feel when you touch a nail immediately after it is hammered into a wooden plank? Why?
Answer:
The nail becomes hot due to friction. Friction changes kinetic energy to heat.

Question 5.
How does the friction arise between the surfaces of two bodies in relative motion?
Answer:
The force of friction is arised by the interlocking of the irregularities of the two surfaces.

Question 6.
Name two instruments, which help to measure the pressure of a fluid.
Answer:

1. Manometer
2. Pressure gauge.

Question 7.
Define one atmosphere.
Answer:
The pressure exerted by this mercury column is considered as the pressure of magnitude ‘one atmosphere’ (1 atm).

Question 8.

Answer:
Broader straps are provided on a back – pack for giving less pressure on the shoulders by providing a larger area of contact with the shoulder.

Question 9.
How does surface tension help a plant?
Answer:
Water molecules rise up due to surface tension. Xylem tissues are very narrow vessels present in plants. Water molecules are absorbed by the roots and these vessels help the water to rise upward due to “capillarity action” which is caused by the surface tension of water.

Question 10.
Which has greater viscosity, oil or honey? Why?
Answer:
Honey has greater viscosity.
Reason : Thicker liquids are more viscous than thinner liquids. As honey has greater viscosity, more frictional force will be acting on it.

X. Answer the following questions with a few sentences (MOT)

Question 1.
Define friction. Give two examples of the utility of friction in day to day life.
Answer:
Friction : Friction is a force that shows down moving objects or prevents stationary objects from moving.
Examples of the utility of friction in day to day life.

• Cars and buses are able to move safely on the road because of friction between the treaded tyres and the surface of the road.
• We are able to write on paper only with the help of friction between the pencil or pen and paper.

Question 2.
Write down three ways of minimising friction.
Answer:
1. By using lubricants:
These are applied to surfaces to reduce the friction between the surfaces. Example Oil, wax, grease and castor oil.

2. With the help of polishing the surface:
We sprinkle fine powder on the carrom board and then we polish its surface to make smooth so that the striker slides easily on the surface.

3. By using ball bearing:
We use leadshots in bearing of a cycle hub because rolling friction is smaller than sliding friction.

Question 3.
How do sailors protect their ship during a heavy storm?
Answer:
During a heavy storm, sailors pour soap powder or oil into the sea near their ship to decrease the surface tension of sea water. This process reduces the impact of the violent water current against the wall of ship.

Question 4.
Write down three applications of Pascal’s law.
Answer:

1. In an automobile service station, the vehicles are lifted upward using the hydraulic lift, which works as per Pascal’s law.
2. The automobile brake system works according to Pascal’s law.
3. The hydraulic press is used to make the compressed bundles of cotton or cloth so as to occupy less space.

Question 5.
Why is a ball bearing used in a cycle hub?
Answer:
The rolling friction is smaller than sliding friction, sliding is replaced by rolling with the usage of ball bearings. So lead shots are used in the bearing of a cycle hub.

XI. Answer the following questions in detail

Question 1.
“Friction is a necessary evil”- explain.
Answer:
Friction is a necessity in most of our day to day activities. It is desirable in most situations of our daily life.

1. We can hold any object in our hand due to friction.
2. We can walk on the road because of friction. The footwear and the ground help us to walk without slipping.
3. Writing easily with a pen on paper is due to friction.
4. Automobiles can move safely due to friction between the tyres and the road. Brakes can be applied due to frictional resistance on brake shoes.
5. We are able to light a matchstick, sew clothes, tie a knot or fix a nail in the wall because of friction.

Though it is giving a negative effect, in most of our day to day life friction helps us to make our life easy. So, it is called as “necessary evil”.

Disadvantages of friction:

1. Friction wears out the surfaces rubbing with each other, like screws and gears in machines or soles of shoes.
2. To overcome the friction an excess amount of effort has to be given to operate a machine. This leads to wastage of energy.

Question 2.
Give the different types of friction and explain each with an example.
Answer:
Friction can be classified into two basic types:

1. Static friction
2. Kinetic friction.

1. Static friction : The friction experienced by the bodies, which are at rest is called static friction. (E.g : All the objects rigidly placed to be at rest on the Earth, a knot in a thread.

2. Kinetic friction : Friction existing during the motion of bodies is called kinetic friction.

Further, kinetic friction can be classified into two:

• Sliding friction
• Rolling friction.

1. Sliding friction : When a body slides over the surface of another body, the friction acting between the surfaces in contact is called sliding friction.

2. Rolling friction : When a body rolls over another surface, the friction acting between the surfaces in contact is called rolling friction. Rolling friction is less than sliding friction. That is why wheels are provided in vehicles, trolleys, suitcases etc.

Question 3.
Describe an experiment to prove that friction depends on the nature of a surface.
Answer:
To understand about the frictional force between the layers of liquid in motion.
Materials required : Different kinds of liquid (coconut oil, honey, water, ghee), glass plates – 4 nos.
Procedure :

• Take a small quantity of different kinds of liquid like coconut oil, honey, water and ghee etc., in a cup.
• Place one drop of each liquid on a separate glass plate.
• Next, gently raise one end of the glass plate, one by one, so as to allow the liquid to slide down the smooth surface of the plate.
• Observe the speed of each liquid.

Observation:
Each liquid moves with a different speed. Water flows faster than other liquids. Coconut oil flows with a moderate speed. Ghee flows very slowly.

Inference:
Between the layers of each liquid, in motion, there is a frictional force parallel to the layers of the liquid. This frictional force opposes the motion of the liquid layers while they are in motion.

Question 4.
Explain how friction can be minimised.
Answer:
1. Using lubricants:

• A substance, which reduces the frictional force, is called a lubricant. Example: Grease, coconut oil, graphite, castor oil, etc.
• The lubricants fill up the gaps in the irregular surfaces between the bodies in contact. This provides a smooth layer thus preventing a direct contact between their rough surfaces.

2. Using ball bearing:
Since, the rolling friction is smaller than sliding friction, sliding is replaced by rolling with the usage of ball bearings. We can see lead shots in the bearing of a cycle hub.

Question 5.
Describe an experiment to prove that the pressure in a liquid increases with depth.
Answer:
Take a plastic bottle. Punch three holes on its side in the same direction, but at different heights. Now pour some water into it and let it flow through the holes. Observe the flow of water.

Inference:
The water comes out from all the holes with a different force and falls on the table at points that are at variable distances from the bottle. Water from the lowest hole comes out with the greatest force and falls at a point that is at the maximum distance from the bottle. Water from the topmost hole comes out with the least force and falls at the point that is at the minimum distance from the bottle.

Reason:
This activity confirms that the pressure in a liquid varies with the depth of the point of observation in it.

XII. Hot Corner

Question 1.
Why is it not advisable to take a fountain pen while travelling in an aeroplane?
Answer:
Fountain pens are built in such a way that the pressure inside them balances the atmospheric pressure at sea level. Since atmospheric pressure decreases with an increase in height above sea level, the pressure inside the pen turns out to be much greater than the air pressure in an aeroplane and the pen starts leaking.

Question 2.
Is there any possibility of making a special device to measure the magnitude of friction directly?
Answer:
Yes. Tribometer is a special device to measure the magnitude of friction directly.

Question 3.
Vidhya posts a question: Mercury is costly. So, instead of mercury can we use water as a barometric liquid? Answer to Vidhya and explain, the difficulty of constructing a water barometer.
Answer:

1. Mercury is commonly used in barometers because of its high density means the height of the column can be a reasonable size to measure atmospheric pressure.
2. A barometer using water, for instance, would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference.
3. This is because mercury is 13.6 times more dense than water.

Question 4.
A bubble rises from the bottom of a pond to its surface by increasing its radius by 3 times its value when it was at the bottom. Calculate the depth of the pond. (Hint: Pressure depends on the depth of the pond. Volume is inversely related to pressure.)[Science Olympiad]
Answer:
Solution:
From Boyle’s law P x \(\frac { 1 }{ v}\) (Pressure is inversely proportional to volume)
Initial pressure P₁ = Atmospheric pressure + Pressure of liquid column
∴ p₁ = hpg + Hpg
h = depth of the pond
H = 10 m of water
V₁ \(\frac { 4 }{ 3}\) πr³
P₂ = Hpg
V₂ = \(\frac { 4 }{ 3}\) π(3r)³ = \(\frac { 4 }{ 3}\) x 27 r³ x π
Hence by substituting these values,
P₁ V₁ = P₂ V₂

VIII. Short Answer

Question 1.
Define force. Mention its SI unit.
Answer:
Force is that which changes or tends to change:

1. The state of rest or
2. The state of uniform motion of a body or
3. The direction of a moving body or
4. The shape of a body.

Question 2.
Does the palm apply any force on the ball, when we place our palm in front of a moving ball?
Answer:
Yes, when we place our palm in front of a moving ball, then the palm apply a force on the moving ball and stop it.

Question 3.
Briefly explain how do we experience force in our daily life.
Answer:
Since, there are many actions which give us the feeling of force like we hit or catch many objects in our regular routine. Most of the times, we see that the moving ball stops after sometime and it changes the direction of motion when it is hit by a bat also, when we compress a spring, its shape and size changes.

Question 4.
Can you lift or push a book lying on a table without touching it?
Answer:
No, we cannot lift or push a book lying on a table without touching it, because it is a type of contact forces.

Question 5.
Explain the effect on the pressure when area on which it is applied, decreases.
Answer:
As, we know that pressure is defined as the force acting on a unit area of a surface, then,
Force
Pressure = \(\frac { Force }{ Area}\)
P = \(\frac { F }{ A}\)
p ∝ \(\frac { 1 }{ A}\)
So, pressure is inversely proportional to the area on which force is applied. Therefore with the decrease in area the pressure increases.

Question 6.
Explain the variation of the pressure exerted by liquid with respect to following factors.

1. Amount of liquid
2. Depth
3. Shape and size of container

Answer:
The variation of pressure exerted by liquid with respect to the above factors can be given by,

1. Pressure in a liquid increases with the amount of liquid.
2. Pressure in a liquid increases with depth.
3. Pressure of liquid is independent of shape and size of container.

Question 7.
Give two examples to reduce friction.
Answer:

1. Drops of oil are poured on the hinges of a door to move the door smoothly,
2. Fine powder are sprinkled on the carrom board to reduce friction.

Question 8.
Explain why the cutting instruments are sharpened.
Answer:
Cutting instruments have very small area of cross – section, which lead to the increase in pressure. So they can easily penetrate the surface (pressure is inversely proportional to area). That’s why cutting instruments are usually very much sharpened.

Question 9.
Cooking in a place located at a higher attitude is difficult. Why?
Answer:
At a higher altitude, due to the lack of atmospheric pressure the boiling point of a substance reduces. So, the water boils even at 80° C. At this temperature, the thermal energy that is produced is not sufficient enough for baking or cooking. So, cooking is difficult at higher altitude.

Question 10.
Write about buoyant force.
Answer:

1. An upward force is exerted by water on a floating or a partly submerged body. This upward force is called buoyant force. The phenomenon is known as “buoyancy”.
2. This force is not only exerted by liquids, but also by gases. Liquids and gases together are called fluids.
3. This upward force decides whether an object will sink or float. If the weight of the object is less than the upward force, then the object will float. If not, it will sink.

IX. Long Answer

Question 1.
Explain the advantages and disadvantages of friction.
Answer:
Advantages of friction : Friction is a necessity in most of our day to day activities. It is desirable in most situations of our daily life.

1. We can hold any object in our hand due to friction.
2. We can walk on the road because of friction. The footwear and the ground help us to walk without slipping.
3. Writing easily with a pen on paper is due to friction.
4. Automobiles can move safely due to friction between the tyres and the road. Brakes can be applied due to frictional resistance on brake shoes.
5. We are able to light a matchstick, sew clothes, tie a knot or fix a nail in the wall because of friction. Though it is giving a negative effect, in most of our day to day life friction helps us to make our life easy. So, it is called as “necessary evil”.

Disadvantages of friction:

1. Friction wears out the surfaces rubbing with each other, like screws and gears in machines or soles of shoes.
2. To overcome the friction an excess amount of effort has to be given to operate a machine. This leads to wastage of energy.
3. Friction produces heat, which causes physical damage to the machines.

Question 2.
Define Pascal’s law. Explain the applications of Pascal’s law in our daily life.
Answer:
Pascal’s law : The pressure applied at any point of a liquid at rest, in a closed system, will be distributed equally through all regions of the liquid.
Application of Pascal’s law : Some of the following examples highlight their working according to Pascal’s law.

1. In an automobile service station, the vehicles are lifted upward using the hydraulic lift, which works as per Pascal’s law.
2. The automobile brake system works according to Pascal’s law.
3. The hydraulic press is used to make the compressed bundles of cotton or cloth so as to occupy less space.

Question 3.
What is surface tension? Explain the applications of surface tension.
Answer:
Surface tension is the property of a liquid. The molecules of a liquid experience a force, which contracts the extent of their surface area as much as possible, so as to have the minimum value. Thus, the amount of force acting per unit length, on the surface of a liquid is called surface tension.

Application of surface tension:

1. Water molecules rise up due to surface tension. Xylem tissues are very narrow vessels present in plants. Water molecules are absorbed by the roots and these vessels help the water to rise upward due to “capillarity action” which is caused by the surface tension of water.

2. For a given volume, the surface area of a sphere is the minimum. This is the reason for the liquid drops to acquire a spherical shape.

3. Water strider insect slides on the water surface easily due to the surface tension of water.

4. During a heavy storm, sailors pour soap powder or oil into the sea near their ship to decrease the surface tension of sea water. This process reduces the impact of the violent water current against the all of ship.

Question 4.
Briefly explain the concept of variation of atmospheric pressure.
Answer:

1. Atmospheric pressure vary from place to place and from time to time due to variation in temperature. Even, the density of air decreases with the increase in temperature.
2. So, as a result, the atmospheric pressure also decreases. The atmospheric pressure at a place is because of the weight of air above it.
3. So, if we go higher above the earth surface, the atmospheric pressure decreases, thus at mountain top the pressure is less. The atmospheric pressure at sea level is considered as standard pressure.

X. Thinking Comer : HOTS

Question 1.
Why dams are made stronger and thicker at the bottom that at the top?
Answer:
This is because the pressure of the water is much greater deeper down and the damneeds to be thick at the bottom so that is strong enough to withstand this larger pressure.

Question 2.
Why do scuba divers wear a special suit while they go into deep sea levels?
Answer:
Pressure deep under the sea is so high that if the divers don’t wear specially designed suits, the water pressure will crush their body.

Question 3.
Why are rain drop spherical in nature?
Answer:

1. Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive force of the surface layer.
2. In the absence of other force including gravity drops of virtually all liquids would be approximately spherical.

Question 4.
A liquid flowing out of a very small opening of a tube or tap comes out in the form of fine drops and not as a continuous stream. Why?
Answer:
For a given volume, the surface area of a sphere is the minimum. This is the reason for the liquid drops to acquire a spherical shape.

Question 5.
Trees are greenish. They are greenish at the tip too. How does the water rise upward in a tree or plant against the force of gravity?
Answer:

1. Water can travel to great heights inside plants. Water moves up the xylem through a process called capillary action.
2. During transpiration, water evaporates from holes in the surface of leaves into the air. As water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

Journey by Train Summary

Section – I

This story tells us of an amazing journey by an Englishman Mr. Phileas Fogg. He is a ruthless perfectionist who cares more about the bet than
the native places, he sees on his travels. He will do anything, even lie and cheat, to get what he wants.
Mr. Phileas Fogg along with his French attendant, Passepartout, attempts to go round the world in eighty days by taking a bet for $ 20,000. They travel through some parts of India. That was the time, when the railways were being built in the country. The train started at the scheduled time from Bombay. There were a number of passengers like officers, government officials and merchants in the train. Sir Francis Cromarty, one of Mr. Fogg’s friends, occupied a seat opposite to them. The train passed the bridges, the Island of Salcette, mountains, jungles, forests and the fertile territory of Khandesh.
Passepartout couldn’t believe that he was actually crossing India in a railway train. Tigers and snakes fled at the noise of the train. Elephants stood gazing at the train with sad eyes. At half-past twelve, the train stopped at Burhampoor. The travellers had a hasty breakfast. The train entered the valleys of Sutpour Mountains at three in the morning.

Question 1.
Give a picturesque view through which the train travels.
Answer:

Section – II

The train stopped at 8 o’clock some fifteen miles beyond Rothal. Phileas Fogg and others were annoyed. They were wondering why there was a halt of the train in the midst of the forest. When they enquired, the conductor informed them that the railroad lines ends at Kholby, 50 miles short of Allahabad. The line begins again from there in Allahabad. Sir Francis got angry because they sold the tickets from Bombay to Calcutta, without confirming about the railroad lines.

The passengers had to provide means of transportation for themselves from Kholby to Allahabad. So, Mr. Fogg, his attendant and Sir. Francis planned to reach Allahabad in time by some means of transport, as a steamer was ready to leave Calcutta for Hongkong on the 25th. They had two days left to reach Calcutta.

Discuss and answer – Intext Questions.

Question 1.
Why did the train stop in the middle of the forest?
Answer:
The train stopped in the middle of the forest as there were no railroad lines beyond that place.

Question 2.
Why was Sir Francis angry?
Answer:
There were no railroad lines from Kholby to Allahabad. But the tickets were sold from Bombay to Calcutta. So Sir Francis was angry.

Section – III

After searching the village from end to end, Mr. Fogg and Sir. Francis came back without finding any means of transport. But Passepartout suggested that they can travel on an Indian elephant. As it could travel rapidly for a long time, Mr. Fogg determined to hire it. Even though Mr. Fogg offered excessive amount to hire the elephant, the elephant’s owner refused to hire it. So Mr. Fogg finally purchased the elephant for two thousand pounds. A young man offered his services as a guide to them.

While Mr. Fogg and Sir Francis took the howdahs on either side, Passepartout got on to the saddle-cloth between them. The driver sat on the elephant’s neck and at 9 o’clock set out from the village to Allahabad.

Discuss and answer.

Question 1.
Which mode of transport did Fogg choose?
Answer:
At first, Fogg chose to go on foot to Allahabad. Then he purchased an elephant to take them to Allahabad.

Question 2.
Did he hire Kiouni? Why?
Answer:
No, he did not hire Kiouni, but purchased it for 2000 pounds, because the owner of the elephant intended to make a big bargain and so refused to hire him.

Question 3.
Why was the elephant owner happy with the deal?
Answer:
The elephant owner was happy with the deal because Mr. Fogg offered him 2000 pounds to purchase the elephant.

He was so much blind that he didn’t see the poverty that his family was suffering and had no commonsense to see that Gods would never want a group of people to starve and die.

Why did masterjee tell Salim that he was going to be the last stone-mason in his village?

“Masterjee, Masterjee” Salim, the servant boy entered the workshop. His voice was filled with concern. He held a cup of tea in his hand. The old man lifted his head.

9th Stopping By Woods On A Snowy Evening Question 1.
What information does the poet highlight about the season and the time of the day in the poem?
Answer:
The darkest evening of the year refers to December 21, the longest night of the year, when there is biting cold. The winter season had its spell on Nature. By using the symbol of darkness in the second stanza, the poet brings forth a sense of sadness and peace.

9th Memory Poem In English Question 2.
In which way is the reaction of the speaker different from that of the horse? What does it convey?
Answer:
The speaker is spellbound by the beauty of the place. He forgets his purpose and dwells deep into Nature’s beauty. Completely mesmerised, the speaker who stops for a while, fails to return to his duties. On the other hand, the horse seems to be responsible and more duty-conscious. The horse does not get attracted to the beauty but wants to complete the task. The difference in the attitude displayed by the man and his horse conveys the struggle between human responsibility and one’s pull towards the worldly desires.

9th Poem Question 3.
What are the sounds heard by the poet?
Answer:
Shaking of harness bells and sound of the wind are heard by the poet.

9th English Book Poem Question 4.
The poet is aware of two choices. What are they? What choice does he make ultimately?

The two choices are – either to stop and enjoy the nature standing between the woods and frozen in the darkest evening of a winter season or get back to work. Though the poet is attracted by the beauty, he understands his responsibilities and so continues his journey.

Writing:

G. Answer the following questions in a paragraph about 80-100 words.

(a) It is said that, “the choices made by one, shapes one’s destiny”. Ponder on the thought and write a paragraph.
Answer:
The choices made by one, shapes one’s destiny. This is the theme of the poem ‘Stopping by Woods on a Snowy Evening’ by Robert Frost. The biggest choice that he wrestles with is whether to return to the warmth and safety of the village or to stay and watch the woods fill up with snow. The poet finds it hard to decide. He ultimately decides to return home, but it seems to take all of his will power.

H. Work in pairs and discuss the factors that contribute towards making a choice and make a presentation to the class.
Answer:
Choices are tough and there can be many factors that contribute towards making a choice. Some choices can be based on emotion, while others can be well thought-of and taken with our mind and wisdom. Some choices can even be based on our instinct rather than logic. Say for example an opportunity is brought upon us and we have to make an instant choice. We might decide by just thinking what is right at that moment. But that choice could have the power of deciding the future course of our life. So we must think carefully before making our choices.

The following factors may contribute towards making a choice:

1. 1. Personal likes or dislikes
   2. Good or bad experiences of our past
   3. Social customs and beliefs
   4. Individual level of intellect and wisdom
   5. Differences in age and education
   6. Conscience and sincerity

Stopping by Woods on a Snowy Evening by Robert Lee Frost About The Poet:

Robert Lee Frost (1874 – 1968) was an American poet famous for his realistic depictions of rural life and his command of American colloquial speech. He frequently wrote about settings from rural life in New England in the early twentieth century, using them to examine complex social and philosophical themes. During his lifetime, he received four Pulitzer Prizes for Poetry and was awarded the Congressional Gold Medal in 1960 for his poetic works. Some of his famous works are The Road Not Taken, Fire and Ice, The Oven Bird, West Running Brook, Mending Wall, After Apple-Picking, etc.

Stopping by Woods on a Snowy Evening Summary:

The poet Robert Frost stopped by some woods on a snowy evening. He knew the owner of the woods and where he resided. He knew the owner lived in the village and so he won’t worry about the poet stopping there. He continued watching the natural beauty of the snow covered woods. The horse must have thought it as a strange act to stop there between the woods and the frozen lake in the dark evening. The horse was puzzled that there was no farmhouse nearby so the journey is not complete.

The horse was shaking its head, ringing the bell attached to its harness, as if he was asking his master whether there was any problem as it was unusual for him to stop by the woods in the darkness. Frost enjoyed the woods and wanted to stay there for a long time. But he had other responsibilities in life. He had to go a long way before he slept. So, he could not admire the lovely, dark and deep woods.

He had to move on. The last line of the poem is repeated to attract the attention of the readers. In the very last line lies the allegorical interpretation – sleep may refer to death. We in our real life have many things to look at with awe, many things to enjoy, but in most cases we cannot, simply because we have other things to do in our short lifespan. So we have to move on.

The Wind on Haunted Hill Summary

Section – I

Usha goes for shopping

The wooing wind blew from the Himalayas over the hills and trees. It passed the haunted hill and reached the village, on the slope of the next hill. It tried to blow away the tin roofs, doors, windows, chimneys and clothes even on sunny days.

Usha, her brother Suresh and her friend Binya spread their clothes out to dry, firmly holding them by rocks. They rested awhile there. Usha planned to go for weekly shopping. Binya could not go with her. Suresh was willing but he had to help Grandpa. He was worried about how she would return alone in the dark passing the Haunted hill.

Grandfather told a story about an English family which lived on the Haunted hill a hundred years ago and the family members were killed by lightning. Grandfather had seen the two children of the family often playing in the moonlight near the ruins even now. This frightened them.Usha went for weekly shopping passing the fields, hill, ruins and valley. The ruined house had crumbling walls with wild flowers, a wild plum tree in the floor of the large hall, lizard on the stones and singing bird on the empty window.

Usha bought soap, matches, spices, sugar, pipe stem, exercise book, marbles and necklace at the bazaar.

She went to Aunt Lakshmis house for tea and when the clouds gathered for rain she hurried home after collecting her mother’s slippers from the cobbler.

Storm on the haunted hill

The clouds and thunder were threatening to rain. So Usha hurried to reach home before dark. She did not have an umbrella but only a shawl and a scarf. Now the raindrops came faster. It was dark and lightning. Usha ran to the ruins to take shelter from the heavy winds and rain. She moved sideways to reach the corner of the old roof for shelter but touched a wild cat and was frightened. It was dry and more sheltered at the old fireplace opposite, but she did not know the way in the darkness. Her clothes and long black hair were soaked. The sound of the tin sheets and the storm blotted out all other sounds.

The lightning and thunder were often, Usha remembered grandpas story about lightning killing the English family and prayed it would not strike her. Suddenly when the lightning flashed again, Usha saw two small figures at the opposite wall near the disused fireplace – they could have been the children.

Usha wanted to leave the ruined building after seeing the two ghostly creatures. As she rushed out she bumped on something and screamed. There were reply screams and it was of Suresh and Binya. They had come looking for Usha in the stormy night. They were surprised, relieved and happy. They decided not to go home in the dark, thunder, lightning and rainy night when the paths also had fallen. Together they had warmth and confidence and stayed in the ruins all night, till the morning. They left the ruins on the top of the hill as the rain had stopped, birds began to sing, the sky was pink and bright and Suresh was hungry. As they were climbing down home, Usha saw a hand waving at them from the brow. Binya said it was the sway of the plum tree. But Usha also heard voices on the wind saying ‘Good Bye’. Usha wondered if it was just the wind.

X. Answer In detail.

Question 1.
Describe the graphical method to find the area of an irregularly shaped plane figure.
Answer:
To find the area of an irregularly shaped plane figure, we have to use graph paper.

1. Place a piece of paper with an irregular shape on a graph paper and draw its outline.
2. To find the area enclosed by the outline, count the number of squares inside it (M).
3. You will find that some squares lie partially inside the outline.
4. Count a square only if half (p) or more of it (N) lies inside the outline.
5. Finally count the number of squares, that are less than half. Let it be

For the shape in figure we have the following:
M = 50
N = 7
P = 4
Q = 4
Now, the approximate area of the can be calculated using the following formula.

Area of the leaf = M+(\(\frac { 3 }{ 4 }\)) N + (\(\frac { 1 }{ 2 }\)) P+\(\frac { 1 }{ 4 }\) Qsq.cm
= 52 + 5.25 = 58.25 sq.mm = 0.5825 sq.cm

Question 2.
How will you determine the density of a stone using a measuring jar?
Answer:
Determination of density of a stone using a measuring cylinder.

1. In order to determine the density of a solid, we must know the mass and volume of the stone.
2. The mass of the stone is determined by a physical balance very accurately. Let it be ‘m’ grams.
3. In order to find the volume, take a measuring cylinder and pour in it some water.
4. Record the volume of water from the graduations marked on measuring cylinder. Let it be 40 cm³.
5. Now tie the given stone to a fine thread and lower it gently in the measuring cylinder, such that it is completely immersed in water.
6. Record the new level of water. Let it be 60 cm³

∴Volume of the solid = (60-40) cm³
= 20 cm³ = V cm³ (assume)
Knowing the mass and the volume of the stone, the density can be calculate by the formula:

XI. Questions based on Higher er Thinking skills:

Question 1.
There are three spheres A, B, C as shown below :
Answer:

Sphere A and B are made of the same material. Sphere C is made of a different material. Spheres A and C have equal radii. The radius of sphere B is half that of A. Density of A is double that of C.

Question 2.
Now answer the following questions:

1. Find the ratio of masses of spheres A and B.
2. Find the ratio of volumes of spheres A and B.
3. Find the ratio of masses of spheres A and C.

Answer:
i. Ratio of masses of spheres A and B
M_A : M_B
D × V_A : D × V_B
Let the mass of sphere A = M_A
Let the mass of sphere B = M_B
Mass = Density × Volume
M_A = D_A × V_A
M_B = D_B × V_B (Density is same)
Volume of Sphere A =\(\frac { 4 }{ 3 }\)πr³

ii. Ratio of volumes of spheres A and B
V_A : V_B
8 : 1 (As mass is directly proportional to volume)

iii. Ratio of masses of spheres A and C.

[∴ Density of A is double that of C ]

VIII. Long Answer

Question 1.
How will you find the volume of an irregularly shaped object (stone) by using measuring cylinder?
Answer:

1. Take a measuring cylinder and pour some water into it.
2. Note down the volume of water from the readings of the measuring cylinder.
3. Take it as V₁
4. Now take Q small stone and tie it with a thread.
5. Immerse the stone inside the water by holding the thread.
6. This has to be done such that the stone does not touch the walls of the measuring cylinder.
7. Now the level of water has raised.
8. Note down the volume of water and take it to be V₂

The volume of the stone is equal to the raise in the volume of water.
V₁ = 30cc, V2 = 40cc
Volume of stone = V2 – Vj = 40 – 30 = 10cc

IX. Problems for practice:

mass (M) = Density × Volume
= 10.5 x 50 = 525 g

X. Creative questions: HOTS

Question 1.
Why does an iron needle sink in water, but not an iron ship?
Answer:
Iron needle is compact and its density is 7.6 g/cm³ Thus, as the density of iron needle is more than 1 g/cm³ therefore, it sinks in water. However, the iron ship is constructed in such a way that it is mostly hollow from within, thus, the volume of iron ship becomes very large as compared to its mass and hence its density is less than lg/cm3 . As the density of iron ship is less than 1g/cm³, therefore it floats in water.
