The motion of a point is given by the equations: xൌ expሺ-tሻ and yൌଶ where x and y are in meters and t is in seconds. Find the acceleration of the point at ൌ 1 c. [10pts]

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?
