comment Is a signal traveling through fiber faster than a signal traveling through copper?
@Georg still i don't understand. I haven't been here for pretty much time. I guess i won't be back untill I join masters. We will discuss later.

comment does current product push or pull effect
it's just what people say when they get shock (here in my country where people don't know much about science all those suff). it's not one people, it's lots of people (so i had to consider some logical reason behind it) and i don't find any scientific reason why do people say so?

thanks mark for correction, but could you give expression for time interms of θ

comment What determines the pitch of an explosion?
i think if you have bigger blast then you will have high intensity. pitch in related with the time of explosion. if it exploded quick then it will have low pitch. though not sure.

comment How long it will take for a upright rigid body to fall on a ground
i am thinking that angular acceleration is harmonic in nature. if 'θ' be the instantaneous angle made my tree with the vertical upright, then the θ¨ = g*sinθ. I think if i solve this equation from 0 to π/2 i think i will get the answer, but i, however, am not sure.

can you do this without initial friction and also the time please.
