hi wondering if i could get a little help with this question
A particle with rest mass m has kinetic energy equal to twice its rest energy. The particle decays into 2 photons which emerge in opposite directions, one traveling in the same direction as the particle before its decay. Find...
hi, wondering if anyone could give me a little help with this question
The space and time coordinates of two events are measured in frame S to be:
Event 1: x1 = L, t1 = L/c
Event 2: x2 = 2L, t2 = L/2c
(a) find the velocity of a frame S' in which both events occur at the same time...

Im having some problems with this question
Some cells in the human body have a layer of negative charge on the inner surface and a layer of positive charge of equal magnitude on the outer surface. The charge densities are +/- 5.0e-4 C.m^-2, the cell wall is 5nm thick and the cell wall...
hi I'm having some trouble with this question:
A proton and an alpha particle of identical energy encounter potential barriers of identical height and width. For which is the probability of transmission greatest and why?
thanks
