Textbook Question
Chapter 12.2, Problem 4cT
A third block, C, of the same size and shape as A and B but with slightly greater mass thanblock B is released from rest at the center of the beaker. Two students predict the finalposition of the block and draw the sketch at right.
| Student 1: | Since this block is heavier than block B, it will not go up as high after it is released, as shown at right. |
| Student 2: | Yes, I agree, the buoyant force is slightly less than the weight of this block, so it should come to rest a bit below the surface. |
Explain what is wrong with each statement and with the diagram.

A large tank has a tube coming out of it like a straw, as shown in the picture below. The tube of water is entirely full and closed at the end on the right, while the tank is open to the air.
Rank the pressures at points N, U, C, L, E, A, and R (using <, >, and =). Explain your reasoning.
How does the pressure at point R compare with the atmospheric pressure immediately outside of the straw? Explain your reasoning.
Describe what would happen if you held the right end of the straw (near point R) in place and poked a hole in the end of it. (This is how a siphon works.) Explain your reasoning. (A video of you doing this experiment yourself could be submitted as evidence of your reasoning.)
A cylindrical steel tank with a diameter of 20.0 cm, a length of 150.0 cm, and an overall mass of 150.0 kg is accidently dropped into a lake. What is the cylinder's density in g/cm3? Will it sink or float? Pure water has a density of 1 g/cm3. Show your work.
In the figure at the right is shown three graphs of the shapes of the same taut elastic string in three different circumstances, labeled A, B, and C. In some of the problems below, the string represents a guitar string, tied down at both ends, while in others, it is part of a very long telephone wire whose ends are not shown. Be careful to note which is which for each problem! The string is light enough that the effects of gravity can be ignored. In each case, the bit of string at the position x = 23 cm is painted blue.1. Suppose the three graphs all represent the same string, tied down at x = 0 and x = 70 cm, and at the same tension. What can you say about the three frequencies of oscillation?
