Answers
Answer:
Fission of an atomic nucleus into two parts of the same size caused by the collision of a particle. Nuclear fission may also occur spontaneously in the case of very heavy nuclei; (See 'fission, spontaneous'). The capture of a neutron induces fission of the nucleus of uranium-235. During the fission, in general two - more rarely three - fission products, two to three neutrons and energy are generated.
Nuclear fission
Example for nuclear fission of U-235
In the uranium nucleus the nucleons are bound with an average energy of about 7.6 MeV per nucleon. In the fission product nuclei, the medium binding energy per nucleon amounts to approx. 8.5 MeV. This difference in binding energy of 0.9 MeV per nucleon is released in the nuclear fission. Since the uranium nucleus has 235 nucleons, a quantity of energy of about 210 MeV is released per fission. It is made up of the following partial amounts:
kinetic energy of fission products 175 MeV,
kinetic energy of fission neutrons 5 MeV,
energy of the gamma radiation occurring during the fission 7 MeV,
energy of beta and gamma radiation during the decay of the radioactive fission products 13 MeV,
energy of the neutrinos 10 MeV.

Course of nuclear binding energy
Due to the neutrons released during the nuclear fission a chain reaction is possible in principle. Facilities where fission chain reactions are initiated in a controlled manner are called nuclear reactors.
Answer:
India is one of the ancient civilisations in the world. It has achieved multi-faceted socioeconomic progress during the last five decades. It has moved forward displaying remarkable progress in the field of agriculture, industry, technology and overall economic development. India has also contributed significantly to the making of world history.
Location
India is a vast country. Lying entirely in the Northern hemisphere the main land extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E.
The Tropic of Cancer (23° 30’N) divides the country into almost two equal parts.
To the southeast and southwest of the mainland, lie the Andaman and Nicobar islands and the Lakshadweep islands in Bay of Bengal and Arabian Sea respectively.
Find out the extent of these groups of islands from your atlas.
Size
The land mass of India has an area of 3.28 million square km.
India’s total area accounts for about 2.4 per cent of the total geographical area of the world.
India is the seventh largest country of the world.
India has a land boundary of about 15,200 km and the total length of the coast line of the mainland including Andaman and Nicobar and Lakshadweep is 7,516.6 km.
