Pythagoras triplets are of the form.
2m, m² -1 and m² + 1.
It is given that smallest number is 8.
So, 2m = 8.
m = 4.
Now, second number = m² -1 = 4² - 1 = 15.
and, third number = m² + 1 = 4² + 1 = 17.
Hence, the triplet is 8, 15 and 17.
Verification :-
17² = 8² + 15²
289 = 64 + 225
289 = 289.
Hence, proved.

Friction is defined as the force that opposes the motion of a solid object over another.
Friction is of 3 types
1)Static friction
2)Sliding friction
3)Rolling friction
Static friction
The maximum fictional force present between any two objects when one object just tends to move or slip over the surface of the other object ,is called static friction.Static friction is a kind of starting fiction because an object just tends to start moving, it does not actually move.
Sliding friction
The frictional force present when one object moves slowly or slides over the surface of another object is known as sliding friction
Rolling friction
When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction.
It is always easier to roll than to slide an object over another object.So rolling friction is much less than the sliding friction.

Ans-In olden days, people did not have the means to understand or explain certain natural phenomena such as eclipse and earthquakes. Hence, they tries to explain such phenomena through stories. These stories are called myths.

- This system of land revenue was instituted in the late 18th century by Sir Thomas Munro, Governor of Madras in 1820.
- This was practised in the Madras and Bombay areas, as well as Assam and Coorg provinces.
- In this system, the peasants or cultivators were regarded as the owners of the land. They had ownership rights, could sell, mortgage or gift the land.
- The taxes were directly collected by the government from the peasants.
- The rates were 50% in dryland and 60% in the wetland.
- The rates were high and unlike the Permanent System, they were open to being increased.
- If they failed to pay the taxes, they were evicted by the government.
- Ryot means peasant cultivators.

Different fuels produce different amounts of heat on burning.
The amount of heat produced by the complete burning or combustion of 1Kilogram of a fuel is called its calorific value.
The calorific value of a fuel is expressed in the unit of Kilojoules per kilogram.
For Ex:The calorific value of kerosene is 45000KJ/Kg means when 1Kg of kerosene is burned completely then 45000 KJ of heat energy is produced.
The calorific value of a fuel is also known as heat value.
The calorific value of LPG is 55000KJ/Kg means when 1Kg of LPG is burned completely then 55000 KJ of heat energy is produced.

As we know that the L.C.M for 4 and 2 is 4
Now,
1/4 = 1/4
1/2 = (1×2)/4
= 2/4
1/4 = (1×20 / 4×20)
= 20/80
1/2 = (2×20 / 4×20)
= 40/80
Here, we now know that 21, 22, 23,…39 are integers between numerators 20 and 40.
Hence the rational numbers between 1/4 and 1/2 are 21/80, 22/80, 23/80, …., 39/80

The company brought reinforcements from England, passed new laws so that the rebels could be convicted with ease, and then moved into the storm centres of the revolt. Delhi was recaptured from the rebel forces in September 1857.
The last Mughal emperor, Bahadur Shah Zafar was tried in court and sentenced to life imprisonment. His sons were shot dead before his eyes. He and his wife Begum Zinat Mahal were sent to prison in Rangoon in October 1858. Bahadur Shah Zafar died in the Rangoon jail in November 1862.
The recapture of Delhi, however, did not mean that the rebellion died down after that. People continued to resist and battle the British. The British had to fight for two years to suppress the massive forces of popular rebellion.

ideas of freedom, equality and participation
India became independent on 15 August 1947. Many sections of society participated in the struggle. People from various backgrounds joined the struggle and they were inspired by the ideas of freedom, equality and participation in decision making. Under colonial rule, the people had lived in fear of the British government and did not agree with many of the decisions that they took. But they faced grave danger if they tried to criticise these decisions. The freedom movement changed this situation. The nationalists began to openly criticise the British government and make demands.

The role of Bacteria in Agriculture:
- Nitrogen-fixing bacteria
The conversion of atmospheric nitrogen into forms of nitrogenous compounds usable by plants is. bacteria living in the root nodules of legume plants fix nitrogen from the atmosphere. Microorganisms in the soil convert atmospheric nitrogen into ammonium compounds, thereby enabling the plants and animals. Nitrogen is an essential constituent of nucleic acids, chlorophyll and vitamins. Rhizobium, Azobacter and Clostridium are species of bacteria which are capable of converting atmospheric nitrogen into forms usable by plants. Plants cannot use nitrogen in elemental form; hence the role of the nitrogen-fixing bacteria becomes very important
- Nitrifying bacteria
Nitrifying bacteria convert nitrogenous waste from dead plants and animals present in the soil into nitrates by the process called as nitrification. In this process, certain ammonifying bacteria like Bacillus and Clostridium first convert nitrogenous waste into ammonia. This ammonia is then converted into ammonium compounds by the same ammonifying bacteria. The ammonium compounds are then converted into nitrites by nitrifying bacteria such as Nitrosomonas, Nitrococcus and then into nitrates by nitrifying bacteria such as Nitrobacter.
- Denitrifying bacteria
Denitrifying bacteria like Pseudomonas putida and Bacillus subtilis are also present in the soil. These bacteria break down nitrates in the soil and release free nitrogen gas, which then enters the atmosphere.
- Scavenging Role
Saprophytic bacteria obtain food from organic remains such as animal excreta, fallen leaves, meat etc. They decompose these substances by the action of digestive enzymes aerobically or anaerobically (known as fermentation). Thus they help in sanitation of nature, so also known as scavengers. E.g.Pseudomonas.
- Production of fuel
Bacteria, while converting animal dung and other organic wastes to manure, help in the production of fuel that is a must in gobar gas plant.
- Disposal of sewage
Bacteria help in disposal of sewage by decomposing it and thus, help in environmental sanitation.

The British had tried their best to win back the loyalty of the people.
They announced rewards for loyal landholders would be allowed to continue to enjoy traditional rights over their lands. Those who had rebelled were told that if they submitted to the British, and if they had not killed any white people, they would remain safe and their rights and claims to land would not be denied.

The Mughal dynasty had ruled over a large part of the country. Most smaller rulers and chieftains controlled different territories on behalf of the Mughal ruler. Threatened by the expansion of British rule, many of them felt that if the Mughal emperor could rule again, they too would be able to rule their own territories once more, under the Mughal authority.
