8. a thin slice of silicon that contains many solid-state components is a(n) a) transistor b) intergratef circuit c) diode d) cathode-ray tube 9. a current of 6.0 amps passed through a motor that has a resistance of 5.0 ohms. clacukate the power a) 30 watts b) 150 watts c) 180 watts d) 900 watts if you have the answers to the electricity and magnetism unit test i'd really appreciate all of them, i have less than an hour to finish this, yikes.

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?
