Nuclear Fission and Fusion

H Manishankar Asked:

which releases more energy?fusion or fission?

Ans:

per fission energy is more for fission, Per unit mass energy released is very much more for fusion

 

Mani again:

ok..bt our nuclear weapons are not powerful enough .. their energy is infinitesimally smaller than d energy released in natural process like earthquake volcano

Ans: Nuke weapons are targeted and sufficient to produce local destruction

Matter, Antimatter and Einstein’s equation

It is my understanding that when antimatter comes in contact with matter that there is nothing left but pure energy.

And since energy and matter are interchangeable (E=Mc2) doesn’t that mean you are actually left with all matter and no antimatter?

Asked Ken

Answer:

The equation E = mc2 tells about mass – energy relation and both matter and antimatter has a positive mass.
