PHYSICS 241 EXAM I Feb. 20, 2001 Name: ID#: This is a closed book exam. Print and encode your name, student ID number, and recita- tion number on the answer sheet. Answers to all the questions arc to be recorded on the answer sheet. There are 10 multiple choice questions for a total of 100 points. Do not do the problems in the order in which they are given. Do the easy problems first. There is only one correct answer to each question. No penalty for a wrong answer. However, all credit for a question will be lost if more than one choice is marked for that question. You may use your crib sheet and calculator. Fill out the op-scan card gradually, as soon as you finish a problem. Do not wait filling out the op-scan card during the last hectic five minutes!
