Charman Fall 2008 last name: first name: signature: student ID#: D/L section #: D/L section time: seat row (letter): seat number: 4 LeConte Hall, 6:10 pm - 8:40 pm, Thursday, October 2, 2008 Problem Points Score 1 50 *2 35 *3 35 *4 35 5 60 RAW TOTAL 215 ADJ. TOTAL 180 Your overall score on Midterm #1 will be the sum of your numerical scores on the FIRST problem (#1) AND LAST problem (#5), PLUS your BEST TWO scores on the remaining THREE problems (#2, #3, #4). Nothing in life is certain except death, taxes and the second law of thermodynamics. All three are processes in which useful or accessible forms of some quantity, such as energy or money, are transformed into useless, inaccessible forms of the same quantity. That is not to say that these three processes dont have fringe benefits: taxes pay for roads and schools; the second law of thermodynamics drives cars, computers and metabolism; and death, at the very least, opens up tenured faculty positions. Professor Seth Lloyd, MIT, 2004 Some DOs and DONTs: Do spread out in the room as much as possible. Do NOT turn the page and begin the exam until instructed to do so. Do feel free to use an electronic calculator (without wireless capabilities), and ONE double-sided 8 1 2 by 11 inch page of handwritten notes . Do NOT use any other notes, books, references, or electronic devices. Do feel free to keep a beverage and a QUIET snack available, if you need them. Do read through the entire exam before beginning any calculations or analysis. Do raise your hand or come quietly to an aisle or the front to ask a question. Do feel free to use the back-sides of the pages to save trees. Do ask for extra paper if needed. Do remember to clearly label and staple any additional pages you wish graded to the back of your exam. Do ask for clarification if you are unsure about the wording or interpretation of any problem, or are uncertain of what is being asked. Do keep an eye on the board and an ear to the proctor(s) for any hints, corrections, or announcements. Do work to maximize credit try to obtain at least partial credit on each part of every problem; work clearly and write legibly; show all work you wish to be evaluated, using the front and back sides of the exam paper; box or circle final answers wherever possible. Neatly cross out any work that you do not wish to be evaluated. Do explain your reasoning clearly, carefully, and concisely if you do not show relevant work or reasoning for any part of a problem, you may not be awarded any credit, even if the final answer is correct. Do verify dimensions and units. DO pay attention to signs and significant figures, and do clearly state your sign conventions for work and heat flows. Do NOT in general plug in numerical values too early in the calculation, or risk making mistakes that the graders cannot easily assess....
