Answers to PH-132 Spring 2004 Exam 2 This document does not contain the solutions to each of the problems. It contains only the final answers. Use the exam as a timed practice test and check your answers . You may check your solutions with any of the TAs. Remember that you will be graded on your ability to clearly document a formal solution to each problem. All starting equations and algebraic manipulations should be shown clearly. Numbers should be plugged in last. The numbers you are using should be clearly documented. Final answers should be boxed or circled. Final answers (even if correct) without an appropriate solution will receive zero credit. If you are not sure how to arrive at the answer to part of a problem, show as much work as possible to receive partial credit. Your work must show a logical progression from one step to the next.
