What were the changes that took place after the French revolution in France?

2 answers

Yogita Ingle 5 years, 2 months ago

1) The French Revolution led to the end of monarchy in France. A society based on privileges gave way to a new system of governance where equality and liberty was given preference.
2) The Declarations of the Rights of Man during the revolution, announced the coming of a new time. The idea that all individuals had rights and could claim equality became part of a new language of politics.

3) These notions of equality and freedom emerged as the central ideas of a new age; but in different countries they were reinterpreted and rethought in many ways.

4) The lifestyle of the people also changed as the class distinction broke down. .

ANSWER

. A tent is in the shape of a cylinder surmounted by a conical top. If the height and diameter of the cylindrical part are 2.1 m and 4 m respectively, and the slant height of the top is 2.8 m, find the area of the canvas used for making the tent. Also, find the cost of the canvas of the tent at the rate of Rs 500 per m2. (Note that the base of the tent will not be covered with canvas.)

Gaurav Seth 5 years, 1 month ago

Let r m be the radius and l m be the slant height of the cone, then
r = 2 m, and l = 2.8 m
Let r₁ m be the radius and h m be the height of the cylinder, then
Now, r₁ – 2 m and h = 2.1 m
Area of the canvas used
= CSA of cone + CSA of cylinder
= πrl + 2 πr₁h
= πrl + 2πrh [r = r₁]
= π r (l + 2h) m²

and Cost of canvas of the tent
= Rs. (500 x 44)
= Rs. 22,000.

Yogita Ingle 5 years, 2 months ago

(i) The scrapping of Corn Laws lead to free trade of food grains.
(ii) After the abolition of Corn Laws, food could be imported into Britain more cheaply than it could be produced within the country.
(iii) British farmers were unable to compete with imports. Vast areas of land were now left uncultivated, and thousands of men and women were thrown out of work. They flocked to the cities or migrated overseas
(iv) Increase in demand due to fall in prices and increase in income leads to mismatch between demand and supply of food grains.
(v) Many countries of the world like Russia. America and Australia and some eastern European countries started exporting food grains to Britain which gave further set back to the local producers.

Explain the main reason for alienation of Tamil in srilanka..

Posted by Lucifer?? Morningstar?? 5 years, 2 months ago

CBSE > Class 10 > Social Science

1 answers

Yogita Ingle 5 years, 2 months ago

The reasons for the alienation of Tamil People :-

1) The clause of the Act of 1956 introduced by the Sri Lankan Government made the Tamil people alienated in the country. According to the Act, Sinhalese was declared the only national language of Sri Lanka. The Tamil people felt that none of the major political parties were sensitive to their language and culture.
2) They also felt that the constitution and government policies denied them equal political rights.
3) Discrimination against them in getting jobs and other opportunities by ignoring their interests was another reason of their alienation.
4) The Sri Lankan Government followed preferential policies that favoured the Sinhali applicants for university positions and government jobs.
5) The Constitution stipulated that the State shall protect and foster Buddhism.

Prove that 7-2£3 is irrational number

Posted by Srushtita Tirlapur 5 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Gaurav Seth 5 years, 1 month ago

Let 7-2√3 as rational number.

Then,7-2√3=a/b,where a and b are coprime.

Therefore,-2√3=a/b-7

√3=a/-2b -7

Here,a/-2b -7 is a rational number .

We know that √3 is an irrational number.

Hence,our assumption is not correct.

Therefore,7-2√3 is an irrational number.

Writer a note on Stanley miller and Urey's experimenr

Sakshi Jagtap 5 years, 2 months ago

Miller Urey Experiment Stanley L. Muller and Harold C. Urey performed an experiment to describe the origin of life on earth. They were of the idea that the early earth’s atmosphere was able to produce amino acids from inorganic matter. The two biologists made use of methane, water, hydrogen, and ammonia which they considered were found in the early earth’s atmosphere. The chemicals were sealed inside sterile glass tubes and flasks connected together in a loop and circulated inside the apparatus. One flask is half-filled with water and the other flask contains a pair of electrodes. The water vapour was heated and the vapour released was added to the chemical mixture. The released gases circulated around the apparatus imitating the earth’s atmosphere. The water in the flask represents the water on the earth’s surface and the water vapour is just like the water evaporating from lakes, and seas. The electrodes were used to spark the fire to imitate lightning and storm through water vapour. The vapours were cooled and the water condensed. This condensed water trickles back into the first water flask in a continuous cycle. Miller and Urey examined the cooled water after a week and observed that 10-15% of the carbon was in the form of organic compounds. 2% of carbon had formed 13 amino acids. Yet, the Miller and Urey experiments were condemned by their fellow scientists.........hope this helps uhh ?

Sakshi Jagtap 5 years, 2 months ago

STANLEY LLOYD MILLER (March 7, 1930 – May 20, 2007) was an American chemist who made landmark experiments in the origin of life by demonstrating that a wide range of vital organic compounds can be synthesized by fairly simple chemical processes from inorganic substances. In 1952 he carried out the Miller–Urey experiment, which showed that complex organic molecules could be synthesised from inorganic precursors. The experiment was widely reported, and provided support for the idea that the chemical evolution of the early Earth had led to the natural synthesis of chemical building blocks of life from inanimate inorganic molecules.He has been described as the "father of prebiotic chemistry".

Why it is necessary to conserve mineral resources?

Posted by Ria Joshi 5 years, 2 months ago

CBSE > Class 10 > Social Science

1 answers

Yogita Ingle 5 years, 2 months ago

Conservation of mineral resources is essential because they are a country’s valuable possession. Some methods by which we can conserve minerals are:

Minerals should be used in a planned and sustainable manner.
Technology should be upgraded to allow the use of low-grade ore at low costs.
Recycling of metals also results in the conservation of mineral resources.
Non-conventional sources of energy should be harnessed for the generation of electricity.
Small steps should be taken by every individual such as using public transport, car pooling and switching off lights and fans when not in use. (It is because 70% of electricity in India is generated by burning coal). Using power-saving devices also go a long way in conserving minerals and energy resources.
