One proton starts with two times the speed of the other. Assuming there is no delection from the original path, determine the initial speed of...

i know electrons have spin and charge which makes them the smallest magnet. protons also have spin and charge. does this mean they are magnets too with a north and south pole? Precisely where are these poles in relation to the spin axis of the proton and electron?

Since non-SUSY GUT's are in danger of falsification by proton decay experiments, SUSY pushes up the half-lives of protons but even so, GUT-SUSY SU(5) is falsified by proton decay experiments, does SO(10) SUSY predict superpartner masses for LHC to see or observe (or alternatively, if LHC does...

Ive figured out the first parts (a) and (b) but I am stumped on (c). :eek:

as the radius of an electron orbit increases, the total energy of the electron decreases because of the relationship: E=\frac{-Z^2E_o}{n^2} right? does this means that the electron's kinetic energy would also decreas too? if I was asked to find the energy of the shortest wavelength photon...
