Conceptual Questions 1. The 1.0 m 3 volume includes the inner volume of each can which contains air, and is not the volume of the aluminum. 3. Compared with a single nail, the bed of nails allows much larger contact area with the body, therefore, reduce the pressure on the body significantly. 6. The added water increases the pressure uniformly throughout the container by an amount of mgh , resulting in a pressure is greater than the container can withstand. 10. The absolute pressure at the location of the diver mgh P P + = atm . Change in atmosphere pressure P atm will lead to change in the absolute pressure P , which can be detected by the pressure gauge. 11. Both beams experience the same buoyant force because they have the same volume. 12. (a) Same reading. The wood block will float in the water and its weight equals the weight of the water spilled out. Therefore the total weight will not change....
