we know that power=workdone/time,


here workdone is "mgh".


thus power=750x6/15,


                 =300.

The escape velocity from earth is v e .A body is projected with a velocity of 2v e . With what constant vellocity will it move in the inter plan etary space. OPTIONS;- 1 :- V e 2 :- 3^ 1/2...
 
 
Apply conservation of energy. Initially when body is on earth, Total energy = kinetic plus potential. And finally when it starts moving in interplanetary space, assuming potential energy at ...

Oh and btw the answer is 3 1/2 v e :) And a correction, the potential energy will be GMm/R not GMm/R 2 . Use v e in place of GMm/R when you equate the two equations and the entire equation...

Is the resistance of direct current and alternating current in a bulb equal?? why? pls explain.
 
 
The term resistance is a bit comprihensive. If you are talking of net obstruction offered to current, then yes AC obstruction(better impedance) is more than DC obstruction(resistance) The...

a piece of wood from a recently cut tree shows 20 decays per minute.a wooden piece of same size placed in a museueum shows 2 decays per minute.if half life of c14 is 5730 years.then age of...
 
 
N’ = 1/30 dps (dps =disintegration per second) N = 1/3 dps So, N’/N = 1/10 e - t =1/10 Since, 1/ = half life = 5730 yr - t = ln(1/10) So, t = ln(10) X 5730 yr
