An ac series circuit consists of a voltage source of frequency 60 hz and voltage amplitude v, a 529-ω resistor, and a capacitor of capacitance 9.8 μf. what must be the source voltage amplitude v for the average electrical power consumed in the resistor to be 658 w? there is no inductance in the circuit.

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
