LATEST PHYSICS 134 Final EXAMS (WINTER-SPRING SESSION) with 100 CORRECT ANSWERS AND RATONALE (HIGHLY RECOMMEDED)

LATEST PHYSICS 134 Final EXAMS (WINTER-SPRING SESSION) with 100 CORRECT ANSWERS AND RATONALE (HIGHLY RECOMMEDED) Directions: It is important that you provide answers in your own words. Please focus only on information from the text/eBook to create your own solutions. Please do not use direct information from an outside source (especially copying and pasting from an “answer” website). Use of direct information from an outside source is against school policy. All answers will be checked for plagiarism. Instances of plagiarism can result in probation or possible dismissal from the school. Grading: Please be sure to follow all guidelines (number of sentences/showing all calculations) and to provide the correct metric units of measure. All questions are 3.33 points. You MUST include units on all your answers. For any math based questions you must show all your work and explain any numbers that are not clearly understood by the problem. There is a formula sheet for you to use at the end of the exam. 1. How is electric potential energy similar to gravitational potential energy? How is it different? Where will an electron bound in an atom and have the largest electrical potential energy? Both electrical potential energy and gravitational potential energy depend on the positions and locations of the object's charges or mass the energy is acting on. Gravitational potential energy depends on mass whereas electrical potential energy depends on charges. An electron bound in an atom will have the largest electrical potential energy when it is farthest from the nucleus it orbits. 2. What is a transformer? Explain how a transformer works including specific details on step up and step down transformers. A transformer is a device used to change and alternate (step up and step down) voltages using electromagnetic induction. A transformer is useful because it can aid in reducing loss of power from power transmission lines. A transformer works by inducing a changing magnetic field in one coil, which induces a alternating current in a nearby second coil. 3. Write at least 4 to 5 sentences on the different measurements that helped to calculate the speed of light. There are 3 specific experiments mentioned in your textbook. Olaus Roemer demonstrated in his experiment that light travels at a finite speed by measuring the periods of Jupiter's moons. Christian Huygens corrected the discrepancies
