Physics 20484 - Homework #6
Due Monday, April 10 at 9:00 am.
Solve the following problems on your own paper. Please:
- Show all work.
- Put a box around your final answer to each problem.
- Be sure proper significant figures (SF) used for all answers.
- Separate all solutions with a horizontal line on your paper.
- A random selection of five problems will be graded for 20 points each.
- Solutions for suggested odd problems can be seen by following links.
- Solutions for assigned problems will be linked from this page after the due date.
Chapter 31
- #14
- Answer as a pure number, a multiple of omega.
- #20
- From zero to the first maximum is one quarter of a period.
- #26
- This is similar to sample problem 31-3.
- #28
- Use equation 31-39 to find the capacitive reactance.
- #36
- According to the graph, the resonant frequency is 25000 rad/sec.
- #46
- For (e), you can answer by calculating the new impedance. For (d) and (f), you can probably answer without doing any new calculations.
- #60
- Answer with 3 SF.
- #94
- Solve for the impedance first, then finding the inductive reactance should be easy.
- Suggested problems from chapter 31:
- 9, 10, 11, 16, 17, 18, 21, 24, 25, 29, 30, 31, 35, 37, 38, 39, 40, 41, 42, 43, 45, 50, 51, 52, 53, 54, 59, 61, 62, 63, 69, 72, 76, 77, 78, 85, 90, 95
Chapter 32
- #8
- Use equations 32-16 and 32-17 here, then use equation 32-14 to find the displacement current.
- #10
- You can assume there is no current here, so the 2nd term in equation 32-5 is zero.
- #12
- It really helps if you do problem 13 first. You'll use equation 25-9 here. Ultimately, you want to solve for dV/dt.
- #14
- Use equations 32-14 and 32-17. Keep in mind that "A" is the plate area, not the loop area.
- #20
- First, solve for the current using the basic RC circuit techniques. Next, read again the discussion in section 32-4 leading up to equation 32-15. Finally, solve using equation 32-16.
- #24
- Use equations 32-16 and 32-17 for this one.
- Suggested problems for chapter 32:
- 1, 2, 3, 9, 11, 13, 16, 17, 19, 21, 22, 23, 25, 26
