An archer pulls her bowstring back 0.376 m by exerting a force that increases uniformly from zero to 251 n. (a) what is the equivalent spring constant of the bow? n/m (b) how much work does the archer do on the string in drawing the bow? j

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?
