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...

i worked it out, just a simple miscalculation. cheers

hey i just need a lil help with this question An alien spacecraft is flying overhead at a great distance as you stand in your backyard. Yyou see a bright signal light in the spaceship blink on for 190.0 ms. The commander of the spacecraft measures that the signal is on for 12.0 ms...

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
