Q1. A power supply passing through a resistor is supposed to deliver 22-v DC at a max current of 150mA. The transformer's peak output voltage is appropriate to charge capacitor to a full 22V, and the primary is supplied with 60-Hz AC. What value of capacitance will ensure that the output voltage stays within 3 percent of the rated 22v?

Q2. What is the most amounts by which the wavelength of an incident photon could change when it undergoes Compton scattering from an atom or molecule with a 19 u mass? (1 u = 1.66 x 10-27 kg)?
