A 200 keV electron strikes a copper target and is brought to rest producing a single X-ray photon. The photon then enters a carbon target and is scattered by a free electron. What is the Compton scattering angle relative to the direction of the incident X-ray if the energy of the scattered X-ray is 0.11MeV?
(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 12.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mole. (b) Imagine adding electrons to the pin until the negative charge h..
