1. The diameter of the spool on a fisherman's reel is 6 cm when it is fully wrapped with fishing line. After casting his lure 16 meters away into the
water, there is enough line left on the spool such that the spool has a
diameter of 4 cm. The fisherman then reels in the line, turning the bail (the
metal part that wraps the fishing line around the spool) at a constant speed
of 16 rad/s. How long does it take him to reel in the fishing line?

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?

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
