Unformatted text preview: Physics 227 Final Monday, December 20, 2010, 4:00 PM - 7:00 PM Colleage Ave Gym / Gym Annex Your name sticker with exam code 1. Use a #2 pencil to make entries on the answer sheet. Enter the following id information now, before the exam starts . 2. In the section labelled NAME (Last, First, M.I.) enter your last name, then fill in the empty circle for a blank, then enter your first name, another blank, and finally your middle initial. 3. Under STUDENT # enter your 9-digit RUID Number. 4. Under CODE enter the exam code given above. 5. Enter 227 under COURSE. You do not need to write anything else on the answer sheet for now, but you may continue to read the instructions. 6. During the exam, you may use a calculator and are allowed three 8.5 x 11 inch sheets of paper with whatever you want written on it. 7. For each of the 32 multiple choice questions mark only one answer on the answer sheet. There is no deduction of points for an in- correct answer, so if you cannot work out the answer, you should make an educated guess. 8. If you have questions or problems during the exam, raise your hand and a proctor will assist you. We will provide values of physical constants that are needed but not given, but we will not provide equations. 9. A proctor will check your name sticker and your student ID some- time during the exam. Please have them ready. 10. You are not allowed to give help to any other student, ask for help from anyone but a proctor, or change your seat without permission from a proctor. Doing so will result in a zero score for the exam. 11. When you are done with the exam, hand in only this cover sheet and your answer sheet. 12. Please sign above by the name sticker to indicate that you have read and understood these instructions. Possibly useful constants: &quot; = 8.85 10- 12 C 2 /N m 2 , k = 1 / 4 &quot; = 8.99 10 9 N m 2 /C 2 , c = speed of light = 3.00 10 8 m/s,- q electron = q proton = 1.602 10- 19 C, m electron = electron mass = 9.11 10- 31 kg, m proton = proton mass = 1.67 10- 27 kg, = 4 10- 7 Tm = 12.57 10- 7 Tm, and 1 eV = 1.602 10- 19 J. Some metric prefixes: f = femto = 10- 15 , p = pico = 10- 12 , n = nano = 10- 9 , = micro = 10- 6 , m = milli = 10- 3 , k = kilo = 10 3 , M = mega = 10 6 , G = giga = 10 9 1. A square loop and a circular loop of equal area lie in a plane per- pendicular to a uniform magnetic field. Each loop then rotates at the same angular frequency about an axis in its plane pass- ing through its center. In which loop will the root-mean-square average induced emf be greater? a) the square b) the circle c) Depends upon the orientation of the axis in the square. d) Depends on ....
