If you poke a hole into a plastic bottle, and stick a straw in it, and then let the straw connect to a glass cup, and then blow a balloon and stick it on the top of the mouth of the bottle, we will measure how long it takes for the water to move from the plastic bottle to a cup. Will a larger bottle size increase or decrease how fast water goes from the plastic bottle to the cup?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
