32. Where will you experience greater pressure; swimming in the sea or in a swimming pool at the same depth? a. swimming pool c. the same b. depends on the ability of the swimmer d. Sea 33. The atmosphere exerts force on us. Yet we don't crash. Why? a. The pressure exerted by the atmosphere is equal to the pressure exerted by our body. b. The pressure exerted by the atmosphere is greater than the pressure inside our body The pressure exerted by the atmosphere is lesser than the pressure inside our body. d. The atmosphere does not exert pressure. 34. The atmosphere exerts force on us. Yet we don't crash. Why? a. The pressure exerted by the atmosphere is equal to the pressure exerted by our body. b.

Water is denser at deeper levels. c. Water pressure is greater with increasing depth. d. It looks better. 36. Fluid at rest at the bottom of a container is: a. under less pressure than the fluid at the top. b. under the same pressure as the fluid at the top. c. under more pressure than the fluid at the top. d. any of the above, depending on the circumstances. 37. When a body floats on a liquid: a. the buoyant force is greater than its weight. c. the buoyant force is equal to its weight. b. the specific gravity is greater than one. d. the buoyant force is less than its weight. 38.
