In a television picture tube, electrons are accelerated from rest through a potential difference of 12,000 volts and move toward the screen of the tube When the elections strike the screen, x-ray photons are emitted Treat the elections nonrelativistically and determine: the speed of an election just before it strikes the screen the number of electrons arriving at the screen per second if the flow of electrons in the tube is 0 01 coulomb per second A x-ray of maximum energy is produced when an electron striking the screen gives up all of its kinetic energy For such x-rays, determine: the frequency the wavelength the photon momentum
