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 four even problems will be graded for 25 points each.
• Solutions for suggested odd problems can be seen by following links.
• Solutions for even problems will be linked from this page after the due date.

Chapter 12

#2

The Work done *by* the gas, not *on* the gas. Part (e) is the just the sum of the first four parts.

#8

Use the ideal gas law to find n. This uses similar concepts/methods as problem #2. Answer with 3 SF.

#16

Answer with 2 SF. Also see #18 for some useful insights into this kind of problem.

#22

Answer with 3 SF.

#50

Use the 1st law throughout this problem.

#56

See problem #21 for a similar example.

Chapter 13

#2

Answer with 2 SF. Careful with units on this one. Answer (a) only.

#12

Both parts (a) and (b) require work-energy analysis, similar to problems from chapter 5. Sum the works done by all of the relevant forces and set them equal to the change in kinetic energy.

#18

Use equation 13.6 to answer this one.

#20

Careful with units. Keep linear and circular quantities straight, too. Angular speed should be given in rad/sec.

#30

Assume that the tower height is equal to the pendulum length.

#32

Note that a shorter period means that the clock will run fast.

#56

Problems from chapter 6 are similar to this as well as problem 58. Answer with 3 SF.
