Physics Qualifying Examination Problems 1–6 Thursday, August 26, 2009 1–5 pm Problems 7–12 Friday, August 27, 2009 1-5 pm 1. Solve each problem. 2. Start each problem solution on a fresh page. You may use multiple pages per problem. 3. At the top of each solution page put the problem number (1–12) and your Social Security number, but not your name or any other information. Academic Honor Code Students are expected to uphold the Academic Honor Code published in The Florida State University Bulletin and the Student Handbook. The first paragraph is: The Academic Honor System of Florida State University is based on the premise that each student has the responsibility (1) to uphold the highest standards of academic integrity in the student's own work, (2) to refuse to tolerate violations of academic integrity in the University community, and (3) to foster a high sense of integrity and social responsibility on the part of the University community. Specific rules for this exam: 1. Sit only in your assigned seat. 2. All cell phones must be turned off during the exam. 3. You are allowed to bring a hand calculator and a book of math tables, but not one that has a list of physics formulas (e.g. Maxwell's equations or the equations of fluid flow or thermodynamics, etc) or physical constants (e.g. electron mass, acceleration of gravity, etc). If such information should be supplied, it will be included in the statement of the problem (and that is generally the case with numbers like the electron mass, Planck's constant, etc.). 4. you may ask questions to the faculty proctor during the exam. If it is decided something is unfairly left out, that will be announced to everyone in the room. 5. You must not receive any information – verbal, written, or otherwise – from anyone during the exam except the faculty proctor. 6. You must not give any information to anyone during the exam.

Problem 1 One mole of an ideal monatomic gas at an initial volume V 1 = 25 L and pressure P 1 = 10 5 Pa is subjected to the following three step cycle. First, it is heated at constant volume to P 2 = 2·10 5 Pa . Second, it is then isothermally expanded to V 3 = 2 V 1 . Third, the volume is reduced back to V 1 at constant pressure. All processes are quasi-static. The gas constant is 8.314 J/(mole K). (a) Draw the P–V diagram of the cycle indicating the pressure and volume after each step. (b) Find the temperature of the gas at each step of the cycle. (c) Find the heat flow for each part of the cycle. (d) Calculate the efficiency of the cycle.

Problem 2 A mass m is hung from a fixed support on the end of a light unstretchable cord of length L forming a simple pendulum. The mass is pulled to the side so that the cord makes an angle of θ 1 with the vertical. (a) Find the potential energy of the system relative to its lowest position.
