Read this: 1. This is a closed book, closed notes exam. No collaboration. You may not use a calculator. Wireless devices, cellphones, computers and PDAs are forbidden in the room. If you have brought any of these items with you, they must be handed over to a proctor for the duration of the exam. Once you begin the exam you may not leave the room. This exam will end promptly at 1 PM EDT. Violation of these rules constitute academic dishonesty and your exam will be confiscated. 2. Once you are told to begin, write your name at the top of each exam page. Only pages with a name at the top will receive credit. 3. There are 20 questions total on the exam: seventeen (17) multiple choice and three (3) true/false. You are expected to complete all 20 questions worth a total of 100 pts (the point value for each question is clearly indicated). 4. Write your answers in the space provided. If you need more space, come up and get extra blank problem sheets. Do not write on the back of any page. We will ignore anything written there. Use the blue books for scratch paper. You must turn them in at the end of the exam but nothing written in them will be graded. 5. For the multiple choice and true/false questions, you must transfer your answers to the boxes on the first page of each section. If your answer is not transferred, you will not receive a score for that question. For true/false questions, if you answer false, you must provide an explanation or counter-example. 6. It is important that your work be legible and that your reasoning be clear and easy to follow . To receive full credit for a problem, you must demonstrate that you understand the physics involved. Writing down the correct final mathematical expression or numerical answer without providing an explanation is not sufficient. # Score (out of) MC Sub /85 TF Sub /15 Total i
