An evacuated tube uses a potential difference of V = 0.3 kV to accelerate electrons, which then hit a copper plate and produce X-rays. Write an expression for the non-relativistic speed of these electrons v in terms of eV, and m, assuming the electrons start from rest. Calculate the non-relativistic speed of these electrons v in m/s.
An AC voltage with an amplitude of 116 V is applied to a series combination of a 151 ?F capacitor, a 129 mH inductor, and a 23.4 ? resistor. Calculate the power factor at this frequency
