PSEB 8th Class Science Solutions Chapter 11 Force and Pressure

Question 17.
Show experimentally that pressure increases with the depth.
Answer:
PSEB 8th Class Science Solutions Chapter 11 Force and Pressure 2
The pressure of a liquid depends upon its depth. This can be proved by an experiment given below :
Experiment.
Take a deep vessel having atleast three holes at different heights on one side of the vessel as shown in Fig. Fill it with water. We shall find that the jet of water from the lowest hole reaches the farthest. This proves that at the lowest hole, the force or pressure is
maximum. Fig. Pressure increases with depth.

Question 18.
What is atmospheric pressure ?
Answer:
Atmospheric pressure. Our earth is surrounded by an air column. This air column like liquid columns exerts pressure on all the objects lying on earth. This pressure exerted by air of the atmosphere is called atmospheric pressure.

Question 19.
Atmospheric pressure is so great, why are we not crushed by it ?
Answer:
Our body and the bodies of other organisms are made up of cells which have fluids that exert pressure from within. This pressure exerted from the inside of the cell is equal to the atmospheric pressure and prevents us from being crushed.

Question 20.

Long Answer Type Questions

Question 1.
What are the different types of forces ? Give an example of each.
Answer:
Types of forces:
The following are the different types of forces:
1. Muscular force
2. Magnetic force
3. Electrostatic force
4. Gravitational force
5. Frictional force.

1. Muscular force:
The force applied by a living being with its muscles is known as muscular force e.g., bullocks apply muscular force to draw a cart.

2. Magnetic force:
A magnet has the property of attracting things made of cobalt, nickel, iron or steel. The force produced by a magnetic substance is called the magnetic force e.g., a magnet can move small iron pins.

3. Electrostatic force:
When substances like plastic and terylene are rubbed against each other, charge is excited on them. The force produced due to this electricity is called the electrostatic force e.g., when a glass rod is rubbed with silk, the rod moves bits of paper due to electrostatic force.

4. Gravitational force:
The earth exerts a force of attraction on all things on its surface and beyond. The force of attraction exerted by the earth is called the gravitational force or force due to gravity. An object dropped from a certain height falls on the earth due to the gravitational force.

5. Frictional force:
When an object moves along some other object, the force which acts between the surfaces of a contact of the two objects is called the frictional force. The frictional force opposes the motion of the object e.g., a marble rolled on the ground stops after sometime due to the frictional force.

PSEB 8th Class Science Solutions Chapter 11 Force and Pressure

Question 2.
When a force is applied to a body, state its effect.
Answer:
The following conclusion can be drawn about the effect of force applied to an object:

  1. Change in speed : The applied force can produce a change in the speed of an object.
  2. Change in direction of motion : The applied force can change the direction of motion of object.
  3. Change in both speed and direction of motion : The applied force can produce a change in both the speed and direction of motion.
  4. Change in shape and size of the body : The applied force can change the shape and size of an object.

Question 3.
Mention advantages and disadvantages of force.
Answer:
Advantages of force:

  1. Force can move a stationary object. For example, a toy can be moved by applying force.
  2. It can slow down a moving object. For example, a bicycle slows down on applying force due to brakes.
  3. It can change the direction of motion of an object. For example* a batsman hits the ball and changes its direction.
  4. It can change the shape of an object. For example, squeezing a sponge changes its shape.

Disadvantages of a force:

  1. Frictional force is responsible for wear and tear of tyres of vehicles and of our shoes.
  2. Frictional force also generates heat. This can be harmful. The heat produced in moving machines reduces their efficiency.

Question 4.
Describe an experiment to show that pressure is the same at all points at the same depth.
Answer:
PSEB 8th Class Science Solutions Chapter 11 Force and Pressure 4
Experiment.
Take an empty tin can and pierce several holes of equal size at the same height and cover them with cellotape to be opened at will. Now fill the can up to its brim and remove the cellotape in order to open the holes (Fig.). It will be found that water from all the holes traverses equal horizontal distance. This is because of the fact that the pressure at all points is the same at the same depth.

Question 5.
How can you demonstrate the presence of atmospheric pressure experimentally?
Answer:
Experiment.
Take a metallic can. Add little water into it. Remove its cap and heat the can, as shown in Fig. (a). The water boils and steam starts coming out from the mouth of the can. The steam forces out most of the air from the can. Now close the can with an air tight lid. Pour cold water on the can. Due to the cold water, the steam inside the can condenses to a liquid state. A partial vacuum is created. The external pressure (atmospheric) becomes greater than the inside pressure of steam. Hence high external pressure crushes the container [See Fig. (b)].

Spread the wheat straw on a pucca floor and wet properly with water, leave it open for at least 48 hours. Mix wheat bran/husk powder with fertilizers (separately) mentioned in step 1 and moisten with water. Broadcast wheat bran mixture on the wet wheat straw after 24 hours. Mix using pitchforks. Prepare a stack of 5 x 5 x 5 foot high with the help of 3 wooden boards. Stack should not be higher than 5 feet.

3. Turning the compost stack:
Layer of stack is removed from top and all sides, it is thoroughly mixed and wetted. This way the inner part of the stack forms outer part of the new stack and outer part of the original stack goes inside the new stack. Repeat the same process when needed. Turning is necessary to increase the microbial activity which helps in decomposition. Turn the stack every fourth day and add to it. molasses, gypsum, furadan, lindane dust respectively at first, third, fifth, sixth and seventh turning.

The compost prepared from 300 kg wheat straw is used to fill 20-25 crates of the size 100 x 150 x 18 cm. When color of compost is dark brown and there is no smell of ammonia and moisture content is 65-72% then the compost is ready for spawning and pH should be 7.0 to 8.0.

Before spawning, prepared compost is mixed with Bavistin 50% soluble 20 mg per litre. 20 gram Bavistin dust is required for one quintal compost which can be filled in four crates or boxes.

5. Filling crates and spawning:
Dismantle the compost stack and let it attain the room temperature. Take out spawn from the bottles and by using two layer growing method, broad cast spawn on the compost and fill in the boxes. Cover it with thick layer of compost. Broadcast the remaining part of spawn on this layer. Cover the boxes with wet newspaper or other papers.

6. Covering crates with soil:
Crates covered with 80-100% mycelium are covered uniformly with FYM and garden soil in the ratio 4:1 or covered with well rotten rice bran- and gobar gas slurry in the ratio 1:1. Before covering, treat it with 4-5% formalin.

7. Disinfecting soil:
Wet the mix of compost and garden soil. Spray 4-5% of Formalin on it..In addition 20g Furadan per quintal of casing soil is also added. Treated soil is covered with tarpaulin sheet or polythene sheets for at least 48 hours. Then it is opened and turned again and again so that formalin evaporates completely from it.

8. Covering of trays:
After 2-3 weeks of spawning remove the news paper and cover the compost covered with mycelium with a l’to 15 inch thick layer of disinfected soil.

9. Arranging containers:
Trays can be stacked and the area under cultivation can be increased. The trays are arranged one above the other in lines and the lines are 2 to 2.5 feet apart up and below. This way adequate working area is available and no harm is done to small pinheads of mushroom. After picking, the lower most part of the stalk of the mushroom is cut off with the help of a knife and clean mushrooms are collected.

Mention two losses of commercialization of agriculture.
Answer:

  1. Indian farmers did agriculture with ancient methods. That’s why their crops were unable to compete with those crops which were grown with the help of machines. That’s why farmers were unable to take maximum advantage out of it.
  2. A farmer had to sell his crop in market through middlemen and middlemen took their share as well. It led to less profit for farmer.

Question 8.
What was permanent Settlement? What were the economic effects of this system? (P.S.E.B. 2004)
Answer:
Permanent Settlement was a type of land settlement. It was introduced by Lord Cornwallis in Bengal in 1793 A.D. Later on it was also introduced in Bihar, Orissa, Benaras and Northern India. According to this system, zamindars were made the owners of the land. Government fixed the land revenue given by them. They deposited the fixed amount in government treasury. But they collected tax from the farmers according to their wish. If any zamindar was unable to pay the land revenue then government sold some part of his land to complete the amount of fixed revenue.

Economic Impact. Income of government was fixed with this system but it left a very bad impact on farmers. Zamindars started to exploit them. Zamindars were not paying any attention on land reforms. That’s why production of farmers started to reduce day by day.

Question 9.
Write a short note on commercialization of agriculture.
Answer:
Villages, before the British empire in India, were self-dependent. People used to do agriculture whose main aim was to fulfil the needs of the village. Crops were not sold. Other workers of village like blacksmith, carpenter, barber, etc. collectively used to fulfil the needs of the village. But the self-dependency of the villages come to an end after the establishment of the British empire in India. According to new land revenue systems, farmers had to pay the fixed amount to government as land revenue and at a particular time as well. Now the main aim of agriculture was just to earn money. It was known as the commercialization of agriculture. This process of commercialization of agriculture became more complex with the advent of the industrial revolution in England. The farmers were forced to produce those crops which could be used as the raw material in factories of England.

Question 10.
Write a note on Indigo-revolt.
Or
What do you know about Indigo Revolt?
Answer:
Indigo revolt was started by the Indigo-producing farmers against imposing more tax on the production of Indigo. Indigo revolt took place between 1858 to 1860 A.D. in a large part of Bengal and Bihar. Farmers of this area refused to produce Indigo. Government threatened them but they remained stick to their demand. When government took some hard steps then they attacked the factories of the British. All the efforts to stop them gone in vain.

One revolt also took place in Champaran district in 1866-68 A.D. against the cultivation of Indigo. This revolt remained continued till the beginning of 20th century. Then Gandhiji came in their favour and then their problem was solved.

Question 11.
Write a short note on mahalwari system.
Answer:
Mahalwari system was introduced to remove the shortcomings of Ryatwari system. It was introduced in U.P., Punjab and various parts of central India. Main feature of this system was the land was neither associated with any zamindar and nor with any farmer. This system was actually took place with whole community of the village. Whole of the community was responsible to pay land revenue. It was fixed in community that what a farmer has to pay. If any farmer was unable to give his share then it was taken from the community of the village.

This system was known as the best system because features of both the earlier systems were there in it. The only drawback which was there in it was that people had to pay a lot of tax.

Question 12.
Write down the benefits of ryatwari system.
Or
Write a note on Ryatwari system.
Answer:
Thomas Munro was appointed as the Governor of Madras in 1820 A.D. He made a new system of land which was known as Ryatwari system. It was introduced in Madras and Bombay. Government decided to take land revenue from those people who themselves tilled the land. So all the middlemen between government and farmers were removed. This system was much better than the Permanent Settlement. Farmers were made owners of their land. Their revenue was fixed which was 40% to 55% of the total produce. It led to increase in income of the government.

Some defects were also there in this system. This system reduced the community feeling among the people of the village. Importance of Panchayats was reduced. Except this government started to exploit the farmers. Farmers were forced to take loans from moneylenders by mortgaging their lands to them.

Question 1.
Write a note on contract system introduced by Lord Warren Hastings.
Answer:
Meaning of the contract system is the system of giving land on contract. This system was introduced by Warren Hastings. According to this system, land was given for contract of 5 years. Higher bidder was given the contract of land for collection of land revenue for 5 years. Later on in 1777 A.D., this term of 5 years was reduced to 1 year. But this system was very defective. Zamindars or contractors used to collect lot of tax from the farmers. It lead to deterioration of economic condition of farmers.

Question 2.
How were zamindars more benefitted by the Permanent Settlement as compared to the farmers?
Answer:
Zamindars were benefitted by the Permanent Settlement. They became the permanent owners of their lands. They got the right to sell or to change the land. They paid definite land revenue to company but they used to collect more land revenue from the farmers. If any farmer was unable to pay tax they captured his land. Most of the zamindars used to live a leisure life in cities but farmers were forced to live a hell like life. In the end we can say that zamindars were greatly benefitted by the Permanent Settlement as compared to the farmers.

Long Answer Type Questions

Question 1.
What were the consequences of land revenue systems introduced by the British?
Answer:
There were some of the evil consequences of the land revenue systems introduced by the British and these are given below :

  1. Zamindars used to exploit the farmers. Even they committed atrocities on farmers while collecting land revenue. The government did not take care of them.
  2. Zamindars became owners of the land by paying definite land revenue to the government. Now zamindars were free to collect land revenue from the farmers according to their own wish. It led to richness of zamindars. Farmers became poorer with this.
  3. The government itself exploited the farmers of those areas where Ryatwari and Mahalwari systems were introduced. One third or half portion of the total produce was collected as the land revenue. Rate, of land revenue was increased each year.
  4. When land became private property then it started to be divided among the members of family. It fed to division of land into small pieces.
  5. Farmers had to pay their land revenue till a particular date. They were forced to pay the land revenue even in the case of femine, flood, etc. That’s why they had to mortgage their land to moneylenders so that they could get money to pay their land revenue. In this way their debt increased day-by-day and they left with no option except by leaving their right over the land.

Actually the main aim of agriculture related policies of the British government was to get more and more money and to fulfil their administration interests. In the end farmers became poor and they came under the clutches of moneylenders.

Question 2.
Explain in brief the permanent settlement, ryatwari system and mahalwari system introduced under the British rule.
Answer:
Permanent Settlement, Ryatwari and Mahalwari system were the new revenue systems introduced by the British. Their brief description is given below :
1. Permanent Settlement: It was a type of land settlement. It was introduced by Lord Cornwallis in Bengal in!793 A.D. Later on it was also introduced in Bihar, Orissa, Benaras and Northern India. According to this system, zamindars were made the owners of the land. Government fixed the land revenue given by them. They deposited the fixed amount in government treasury. But they collected tax from the farmers according to their wish. If any zamindar was unable to pay the land revenue then government used to sell some part of his land to compensate the amount of fixed revenue.

2. Ryatwari System: Thomas Munro was appointed as the Governor of Madras in 1820 A.D. He made a new system of land which was known as the Ryatwari system. It was introduced in Madras and Bombay. Government decided to take land revenue from those people who themselves used to till the land. So all the middlemen between government and farmers were removed. This system was much better than the Permanent Settlement. Farmers were made owners of their land. Their revenue was fixed which was 40% to 55% of the total produce. It lead t* increase in income of the government.

Some defects were also there in this system. This system reduced the community feeling among the people of the village. Importance of Pancbayats was reduced. Except this government started to exploit the farmers. Farmers were forced to take loans from moneylenders by mortgaging their lands to them.

3. Mahalwari System: It was introduced to remove the shortcomings of the Ryatwari system. It was introduced in U.P., Punjab and some parts of Central India. The main feature of this system was that land was neither associated with any zamindar and nor with any farmer. This system was actually taking place with whole community of the village. Whole of the community was responsible to pay land revenue. It was determined in community that what a farmer has to pay. If any farmer was unable to give his share then it was taken from the community of village.

This system was known as the best system because features of both the earlier systems were there in it. The only drawback which was there in it was that people had to pay a lot of tax.

PSEB 8th Class Social Science Solutions Chapter 12 Rural Life and Society

Question 3.
What was permanent system? Mention its benefits and losses.
Answer:
During the time of Lord Clive, the British East India Company got the Diwani Rights of Bengal, Bihar and Orissa from the Mughal Emperor. The Company had no means to collect the taxes. Therefore, the work regarding the collection of land revenue was given to the local officers. The method of collecting revenue by these officers was very faulty. Warren Hastings, therefore, made some reforms in this system. But neither the landlords were happy nor the income of the Company was increasing. Cornwallis, therefore, introduced what is called the ‘Permanent ^Settlement’ of land. This system was started in 1793 A.D.

Benefits of Permanent Settlement. The following were the advantages of the Permanent Settlement:

  • Income of the Company became certain. Now it was easy for the Company to prepare its budget.
  • Landlords were now made permanent owners of the land. They, therefore, started making improvements in agriculture and to make their lands fertile.
  • Now the Company had not to assess the land revenue time and again.
  • As the landlords were made the permanent owners of land, they were pleased with the British and sided with the government in times of internal revolts.

Losses:

  1. Landlords became the permanent owners of the land as a result of this settlement. It gave birth to a new class of landlords loyal to the British.
  2. Landlords who lived away from their lands were adversely affected. They could not collect revenue from the farmers and were unable to deposit it with the government in time. As a result, they had to sell their lands to pay the tax.
  3. Due to lack of proper measurement of land, less revenue was fixed. As a result thereof, income of the landlords increased. But the income of the government remained stagnant.
  4. Most of the landlords did not pay attention to the improvement of their lands. They gave their lands on contract and themselves stayed in big cities like Calcutta (Kolkata) and enjoyed a luxurious life there.
  5. The Permanent Settlement did not give due attention to the rights of farmers. They were left at the mercy of the landlords. The landlords collected revenue from them mercilessly and did not behave well with them. As a result, the condition of the farmers worsened.

In brief, we may say that the objective of Lord Cornwallis was to improve the condition of the farmers through Permanent Settlement. But it did not benefit them. Only landlords were benefited. .The condition of the farmers became more miserable.

Question 4.
What were the causes of farmers’ revolt? Explain any one farmer’s revolt.
Answer:
The following were the reasons of revolts of farmers :
1. More taxes: The British introduced new systems of land revenue in their conquered states of India. Farmers were forced to pay high land revenue. That’s why they came in the debt of moneylenders with which their economic condition deteriorated.

2. Sales law: Government introduced sales law according to Permanent Settlement of Bengal. According to this law, if any zamindar was unable to pay his land revenue till March then government was free to sell his land to other zamindar for the recovery of its arear. That’s why zamindars and farmers were very angry with the government.

3. Capturing the Land: Zagirdars were given large pieces of land by the Mughal Emperor as gift. These lands were free of taxes. But these large pieces of land were captured by the British and they again imposed taxes on them. Not only this, taxes were raised. The British took harsh steps to collect taxes.

Farmers’ Revolts:

  1. One revolt took place exactly after the establishment of British rule in Bengal. Farmers, Sanyasi’s and Faqir’s took part in it. They made their groups and even used arms. The British regiments were irritated by these groups. It took 30 long years for the government to suppress this revolt?
  2. Farmers of Chittore and Satara revolted in 1822 A.D. against too much land tax. This revolt was suppressed by the government with the help of military and with politics. Some of the rebels were recruited in police and others were given land to till in die form of grant.
  3. Farmers of the Sendove district revolted against the British government in 1829 A.D. They attacked the British police under the leadership of their leader and they killed a number of Britishers.
  4. Farmers of Ganjam district revolted in 1835 A.D. under the leadership of Dhananjay. This revolt lasted till Feb. 1937. Later on this revolt was also suppressed by government with the help of large number of military forces.
  5. Another farmers’ revolt took place in Sagar in 1842. Its leader was Madhuker, a Bundela Zamindar. A number of police officers were killed by farmers and they plundered many towns.
    A number of farmers’ revolts also broke out against more taxes and the capturing of land by the British. Some of other important farmers’ revolts were revolt of Patiala and Rawalpindi (Modern Pakistan).

Question 5.
Write down about the commercialization of agriculture during the British rule.
Answer:
Villages, before the British empire in India, were self dependent. People used to do agriculture whose main aim was to fulfil the needs of the village. Crops were not being sold. Other workers of village like blacksmith, carpenter, barber, etc. collectively fulfilled the needs of the village. But the self-dependency of the villages come to an end after the establishment of the British empire in India.

According to the new land revenue system, farmers had to pay the fixed amount to the government as land revenue and at a particular time as well. Now the main aim of agriculture was just to earn money. It is known as the commercialization of agriculture. This process of commercialization of agriculture became more complex with the advent of the Industrial Revolution in England- Now farmers were forced to produce those crops which could be used as the raw material in factories of England.

Impact of Commercialization
Merits:

  • Production of different types of crops was increased.
  • Means of transport were developed to take crops to markets of cities.
  • Things became very cheap due to more production.
  • Farmers came in contact with urban areas because of which their point of view was changed. As a result, national consciousness aroused among them.

Demerits:

  1. Indian farmers used to do agriculture with ancient methods. That’s why their crops were unable to compete with those crops which were grown with the help of machines. That’s why farmers were unable to take maximum advantage out of it.
  2. Farmers had to sell their crops in the market through middlemen and middlemen took their share as well. It led to less profit for farmers.

Question 8.
Write notes on:
(а) Adam’s apple.
(b) Secondary sexual characters.
(c) Sex determination in the unborn baby.
Answer:
(a) Adam’s apple.
PSEB 8th Class Science Solutions Chapter 10 Reaching the Age of Adolescence 1
At puberty boys develop larger voice box or larynx. This box in boys is seen as a protruding part of the throat called Adam’s apple.

(b) Secondary sexual characters.
We know testis and ovaries are the reproductive organs. They produce the gametes i.e. sperms and ova. In girls, breasts begin to develop at puberty and boys begin to grow facial hair, i.e. moustaches and beard. As these features help to distinguish the male from the female they are called secondary sexual characters. Boys also develop hair on their chest. In both boys and girls hairs grow under the arms and in the region above the thighs or the pubic region.

(c) Sex determination in the unborn baby.
Determination of the sex of child. Sex chromosomes determine sex in human beings. In males, there are 44 + XY chromosomes, whereas, in females there are 44 + XX chromosomes. Here X and Y chromosomes determine sex in human beings.

Two types of gametes are formed in male, one type is having 50% X-chromosome, whereas, other type is having Y-chromosome. In female, gametes are of one type and contain X-chromosome.

Thus females are homogametic. If male gamete having Y-chromosome undergoes fusion with female gamete having X-chromosome the zygote will have XY chromosome and this gives rise to male child.

If male gamete having X-chromosome undergoes fusion with female gamete having X-chromosome, the zygote will be having XX-chromosome and this gives rise to female child.
