Nuclear fission, as a source of energy, can be used for the benefit of mankind'- discuss in short .

Energy evolved during nuclear fission can be used for the welfare of mankind' - discuss briefly .

How can nuclear fission be utilised for mankind?

Which of the following sources of energy cannot be used as a source of energy on a coludy day?

[A] : The energy derived from enzyme-sub-strate interaction , is called energy of formation . [R] : Free energy is the major source of energy used by enzymes to lower the activation energies of reactions .

Explain how a potentiometer can be used as the source of varying electromotive force?

Nuclear fusion occurs among deuterium nuclei when the average kinetic energy of a nucleus is 0.72 MeV. At what temperature can this nuclear fusion occur? 1 ev=1.6 times 10^-19 J,k=1.38 times 10^-23 J.K^-1

In has been estimated that the total energy radiated by the sun is 3.8xx10^26 J per second. The source of energy of stars is a thermonuclear reaction called nuclear fusion. Fusion reactions are not controlled. It is presumed that the energy of stars is due to two processes called proton-proton cycle and carbon nitrogen cycle. Fusion cannot take place at ordinary temperature. This, hydrogen bomb uses a small fission bomb, which on explosion causes the temperature to rise very high about 10^7 K. We have yet to see how a hydrogen bomb can be used for peaceful life-sustaining purpose. Energy released in the process of fusion is due to mass defect. It is also called Q-value. Q =Deltamc^2 , Deltam= mass defect Answer the following questions based on above passage: Fusion reaction takes place at about:

Mention peaceful use of nuclear energy?

Do you think microbes can also be used as source of energy? If yes, how?

Discuss the ways how the use of energy could be done as minimum as possible.
