1 A hollow hemisphere is placed against a flat circular plate of the same radius r . The air in between is pumped out so that atmospheric pressure P holds them together. The net force on the outer surface of the hemisphere due to atmospheric pressure is: A. less than B. the same as C. greater than the net force due to atmospheric pressure on the flat plate. Two hollow hemispheres of radius r are placed against each other. The air in between is pumped out so that atmospheric pressure P pushes them together . If two people tug on them, what force much each exert to pull them apart? F F F = ? A. π r 2 p / 2 B. π r 2 p C. 2 π r 2 p D. 4 π r 3 p / 3 E. π r 3 p Three water-filled containers are shown below. (A) (B) (C) For which container is the pressure of the water on the base of the container largest ? A. (A) B. (B) C. (C) D. All pressures are the same E. Insufficient information Three water-filled containers are shown below.
