Nuclear Reactions
Nuclear reactions are those reactions where in a nucleus when bombarded with nucleons or other sub-atomic particles; undergoes a change in its compositio..
Nuclear Chain Reaction
A nuclear chain reaction occurs when on an average more than one neutron from a nuclear fission reaction causes another fission reaction. The reaction taking place in an atom bomb is an uncontrolled chain reaction. Whereas in a ..
Artificial Nuclear Reactions
Artificial Nuclear Reactions - Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess ra..

If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess ra..Nuclear Fission Reaction
. Nuclear energy is produced in a nuclear reactor which is a device to generate electricity and used Uranium-235 as its fuel. In this reactor the energy released is controlled or sustained which is called as sustained fission reaction. Otherwise the energy goes out of ..
Controlled and Uncontrolled Nuclear Reactions
Once the nucleus has been divided by fission, the neutrons that are emitted can strike other nuclei. This energy released is extremely large. The neutrons produced during the fission are called secondary neutrons. These neutrons may bring about the fission of three more 9 2 U 2 3 5 nuclei and..

Nuclear Energy
This is another important source of energy that is obtained from the energy that is stored in the nucleus of an atom. This stored energy can be obtained by carrying out two types of nuclear reactions called nuclear fission reaction and nuclear fusi..
Nuclear Fusion
Though the energy liberated per fusion is smaller that that liberated per fission of U-235 (which is about 200 MeV). Yet the hydrogen bomb is much more powerful than the atomic bomb for the following reasons: i) Mass per atom of deuterium as well as tritium is much smaller than that of uranium. ii)..

Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
