When you look at a process using the point of view of energy as opposed to the point of view of forces, typically? A. you use the exact same equations.
B. you predominantly use vector quantities.
C. you use more math, but it's less abstract.
D. you use less math, but it's more abstract.

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?
