comment How long it will take for a upright rigid body to fall on a ground
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.

can you give some reference to such functions? It might be helpful

comment Is a signal traveling through fiber faster than a signal traveling through copper?
@Frédéric now i do understand my mistake. I realized that signal is an voltage or electric field rather than frequency of alternating current. But if I put one end of wire here and other other half way around the world, my question is how fast will it take to reach the signal. I guess electric field travels at the speed of light.

comment Is a signal traveling through fiber faster than a signal traveling through copper?
@Frédéric I do understand the speed of signal is the speed of waves inside the cable. I was merely implying that the waves are the flow of electrons in the cable after all (because it is impossible to transfer signal as heat). and certainly the rms speed of electrons is in the order of 10*6 or something. while the speed of light in the optical fiber is at the speed of light. so .. correct me if i am wrong.

I think the speed of signal in copper is related to rms speed of electron that is significantly less than speed of light.

comment Why do liquids separate in space?
Comparable to Liquid Drop Nuclear Model. The tension in the liquid is conserved and liquid breaks if the tension breaks the limit. If tension is unable to break the liquid drop then it stays as it is.
