Can light do some mechanical work?
“We know that sound can cause some mechanical work(eg:when we keep our hand in front of a large speaker,we feel something hitting the back of our hand), but why this doesn’t happen with light??” -Manishankar asks.

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

Time Dilation in Relativity
Manishankar asks: “When we match the speed of light,it is said that time drags..does that mean we become old a little slower?If so,how?”
