Question # 1

Discuss the advantages of fission power from point of view of safety,pollution and resources.

Ans 1: Advantage of nuclear power are given below
1. Nuclear fission energy,release a highly reduced amount of the gases into the air,resulting in a slower rate of global warming and pollution.
2. The energy is quick to create;meaning that they are able to make a large amount of some form of emergency required it.
3. Much more energy is produced.

Question # 1

Define Half line and discuss its dependence.

Ans 1: The half line T_1/2of a radioactive elements is that period in which half of the atom decay.
Dependence: The number of decaying atoms is proportional to the number of atoms present in the beginning of the period and is proportional to time interval.

Question # 1

Distinguished between nuclear fission and nuclear fusion.

Ans 1: Nuclear Fission: Such a reaction in which a heavy nuclei like that of uranium splits up into two of roughly equal size along with the emission of energy is called fission reaction.
Ans 2: Nuclear Fusion:A reaction in which two lights nuclei merge to form a heavy nucleus is called fusion reaction.It require very high temperature.
