Predict/Explain In the preceding problem, suppose the block of wood with the ball "high and dry" is floating in a tank of water. (a) When the block is inverted, does the water level in the tank increase, decrease, or stay the same? (b) Choose the best explanation from among the following:
I. Inverting the block makes the block float higher in the water, which lowers the water level in the tank.
II. The same mass is supported by the water in either case, and therefore the amount of displaced water is the same.
III. The inverted block floats lower in the water, which displaces more water and raises the level in the tank.
