An X-ray photon of wavelength 0.978 nm strikes a surface. The emitted electron has a kinetic energy of 975 eV.
What is the binding energy of the electron in kJ/mol?
[KE = 1/2mv^2; 1 electron volt (eV) = 1.602 x 10^-19]

Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
An input signal of 10V at 0degrees and a frequency of 1592Hz is applied to a series RLC circuit with resistor R=100ohm, inductor L= 40mH, and a capacitor C=0.5uF. The value of the total circuit complex impedance is
An electron in the n = 7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 397nm. What is the value of n for the level to which the electron relaxed?
These electrons cause the emissions of secondary electrons-called auger electrons-from the metal surface. The kinetic energy of the auger electrons depends on the composition of the surface
