Unformatted text preview: University of Maryland Department of Physics Physics 122 Dr. E. F. Redish Spring 2009 Final Exam 20. May 2009 *** Good Luck *** (175 points) Post grades on web? (Initial , please) Yes____ No____ (If you agree, I will post your grades and your detailed scores for each category on our website by the last 4 digits of your student number.) Instructions: Do not open this examination until the proctor tells you to begin. Read these instructions while waiting. 1. When the proctor tells you to begin, write your name at the top of every page that has a place for it including this one (on the back). (This is essential since exam booklets will be separated for grading.) The first problem booklet contains the short-answer problems. Do your work for these problems (1-6) on the pages for those problems. Write your answers for those problems in the appropriate boxes on the back of this page. Your work on these problems will not be inspected unless there is an ambiguity in your answer. 2. The second booklet contains long-answer problems. Do your work for each of these (I-V) on the page for that problem. (Work on other pages will not be looked at.) If part of your answer is on the back, be sure to check the box on the bottom of the page so the grader knows to look on the back! . 3. On all the problems except short answers , your answers will be evaluated at least in part on how you got them. No credit may be given for answers that do not show how you got them . Partial credit will be granted for correct steps shown, even if the final answer is wrong. 4. Write clearly and logically so we can understand what you are doing and give you as much partial credit as you deserve. We cannot give credit for what you are thinking – only for what you show. 5. If on a multi-step problem you can't do one part, don't give up. Go on to the next part anyway. If necessary, define a name for the quantity you couldn't find and express your answer in terms of it. 6. If you try one approach and then decide on another, cross out the one you have decided is wrong. If your paper has both correct and incorrect approaches the grader will not choose between them. You will not receive credit when contradictory statements are present, even if one is correct. 7. All calculations should be done to the appropriate number of significant figures. 8. At the end of the exam, write and sign the honor pledge in the space below: “I pledge on my honor that I have not given or received any unauthorized assistance on this examination Name_________________________________ Physics 122 Dr. E.
