Homework 2 Physics 204, summer 2008 Part 1 1. Read section 9.1 in Physics: The First Science. The textbook is meant to be an active learning tool. Reading it is very important and you should plan on spending time doing it. The examples are an integrated part of the textbook and the learning process. There are important details, techniques, and information that are presented in the examples so be sure to study them carefully. Also, you should look over any guided review problems that were not assigned as recitation work. Remember that the guided review problems match up with the examples in the chapter, so look there for help in going over the guided review. 2. Chapter 9 guided review 1. Include pictures, either drawn by hand or by taking screenshots. 3. Chapter 9 reasoning skill building 3. The problem should end with “are equal to zero at any point(s) in the vicinity of the 4 charges.” 4. Chapter 9 reasoning skill building 4. In this problem you will need to get familiar with a new unit of energy, the electron volt. Use the Internet and any other resources you have access to to learn how

Unformatted text preview: the electron volt relates to the joule. 5. Chapter 9 problem 2. An “MeV” is a mega electron volt, or 1 million electron volts. 6. Chapter 9 synthesis problems and projects 1. Include pictures, either drawn by hand or by taking screenshots. Part 2 7. Read section 9.1 in Physics: The First Science. 8. Chapter 9 problem 3. 9. Chapter 9 reasoning skill building 7. 10. Chapter 9 problem 6. There is a typo in this problem. The end of the first sentence should read “of water at 20 .” C ° 11. Consider the circuit in the drawing. ( R 1 = 3.0 , R 2 = 36 , V 1 = 30.0 V.) 1 R A 1 V 2 R 8.0 Ω 12.0 Ω 10.0 V B a. Determine the magnitude of the current in the circuit. Hint: Use Kirchhoff’s loop rule. There will be 6 terms, one for each circuit element. b. Determine the magnitude of the voltage between the points labeled A and B . c. Which point, A or B , is at the higher potential. Explain your reasoning....
