8. A driver realizes that she is traveling in the wrong direction on a one-way street. She has already driven 350 meters at a velocity of 16 meters per second, east before deciding to make a U-turn. How
long did it take for the driver to realize her error?

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?
