i woke this morning and came to my sense using your first clue! showing that Work done (and so the change in energy) was not increased. thanks for the help on the subject!

umm I'm not completely sure what you mean? do you mean to use E^2 = p^2 + m^2 and show there is no overall change in momentum?

Homework Statement Given the formula for the force on a charge in an electric and magnetic field is F = eE + ev X B why can the magnetic field never increase the energy of a particle that travels through it Homework Equations N/A The Attempt at a Solution I really am not...

Hi everyone, I'm soon going to be performing a project that looks at quantum turbulence of 3He and 4He, and more specifically how it decays over time depending on the vortex density and temperature. I’ve done much research into the low temperature part of my project however I’ve...

ok well let's say i was to measure the velocity of a small mass particle and one with a larger mass in the lab frame (lets say an electron and proton). if both particle were to have the same wavelength and so same energy would i be correct in saying that due to their sizes it would be...

at what sort of speed ratio (v/c) would one consider relativistic effects to become important? i would probably say when v/c ~ 0.4 as this would make the gamma factor to be ~ 1.1, making a 10% difference (for length contraction, time dilation etc..). is there any "offical" value for where one...

Towards the end of my atomic and quantum course my lecturer makes a note of residual Coulomb interaction and does a few graphs to show the concequences of it are (such as some states not being allowed do to symmetry) and that they favour larger values of angular momentum, but doesn't really...

Homework Statement At the Tevatron you observe the process u ̅u → τ+τ−. Draw the lowest order Feynman diagrams for the processes involved and state which interactions are responsible. Label all internal lines, external lines and vertices [u = up quark, τ = tau lepton] The Attempt at a...

f is the focal length, that is the length at which a lense focuses a given object. using the infomation given you are able to input firstly into the lensmakers equation to find a focal length and then in the standard lens equation to find the image distance for both red and blue light, which...

hey guys first post so sorry if this has already been asked :S what exactly is meant by the separation of variables in the schrodinger equation? also what co-ordinate system would i use to solve for an electron in a hydrogen-like ion? thanks
