Unformatted text preview: Physics 122 Spring 2009 – Third Hour Exam STUDENT ANSWER SHEETS PHYS 122: Third Hour Exam April 10, 2009 Do not open this exam until instructed to do so. Please complete this form and read the rules on this cover sheet now. Your Name: (print neatly!)____________________________________________ Your Case Network ID (Email) (e.g. abc123)____________________________ IMPORTANT: ALSO NEATLY PUT YOUR NAME AND ID ON THE TOP OF EVERY COL- ORED PAGE WITH YOUR WRITTEN WORK! Rules for Exam: This exam is worth 10 percent of your grade. You have 50 minutes to complete the exam. Closed book. Three 8 1 2 × 11 sheets of hand-written notes (both sides) allowed. Answer all questions. Show your work. The correct answer alone with no explanation is worth zero points. Partial credit will be awarded for cases where you have progressed toward the correct answer. If you have a question on the wording of a problem or the interpretation of a problem, raise you hand and a proctor will come to you. Write your answers on the pages provided. Non-programmable calculators are okay, but no PDA’s or laptops. 1. Relax. Don’t panic. 2. Put a box around your final answer. Use English words. Explain. 3. Be as clear as possible when you are working the problems. It helps to draw a picture or say in a few words what you are doing. You will be awarded partial credit for knowing how to solve the problem even if you cannot successfully implement that solution. State clearly the central physics concept associated with each problem. Explain your work. The correct answer alone is worth nothing. 4. You will receive most of the points if you set up the problem clearly and correctly. If you make a math blunder or plug in the wrong numbers at the end, this will cost you a relatively small number of points. 5. Take your time. Do not rush your work. Presentation counts. Neatness counts. Illegible or very untidy answers will be graded as simply wrong. Irrelevant or hostile comments are grounds for lost points. Do not annoy the graders. Show that you care about your work. Go slow, take care, and pace yourself so that you can keep your work organized.
