a. Consider an x-ray machine with a step-up transformer consisting of a primary coil of 100 turns and a secondary one with 50000 turns. If the voltage applied across the primary coil is 100 volts, find the minimum wavelength of a bremsstrahlung photon emitted by the x-ray tube, the frequency of the photon, and the energy of the photon.
b. Identify (via circling and labelling) the anode, cathode, step-up transformer, step-down transformer, the primary and secondary windings of the transformers, and the diodes. Consider the depicted electron. What path would it take to get to the point labelled as a?
When does the Total mechanical energy remain constant?
