Physics 211, Homework Set #7

These problems are due Friday, April 30, at 5 PM. You may place your solutions in the mailbox outside my office door, or bring them into class.

The grading scheme for the homework set is as follows: three of the problems will be chosen to count for 10 points, and you may be given partial credit on them. You will receive 1 point for at least attempting each of the other questions. However, you do not know which of the questions will be chosen for detailed grading ... and therefore you should do them all.
