Question

The three tanks shown above are filled with water to an equal depth. All the tanks have an equal height. Tank A has the greatest surface area at the bottom, tank B the middle and tank C the least. (Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. If the first is F the second L and the rest G, enter FLGGGG). A) The force exerted by the water on the bottom of tank C is ... the force exerted by the water on the bottom of tank A B) The pressure at the bottom of tank C is ... the pressure at the bottom of tank A C) The water in tank C exerts an upward force on the sides of the tank. D) The pressure exerted on the bottom of tank C is smaller than for the other tanks. E) The force due to the water on the bottom of tank C is .... the weight of the water in the tank.

Explanation / Answer

"The pressure at the bottom of tank A is .... the pressure at the bottom of tank B. " Same depth, same pressure: _Equal to_ "The water in tank C exerts a downward force on the sides of the tank." _False_ "The force exerted by the water on the bottom of tank B is .... the force exerted by the water on the bottom of tank A." Since the pressures are the same, but the area of the bottom of tank B is less than the bottom area of tank A [force = (pressure)(area)]: _Less than_ "The pressure exerted on the bottom of tank C is equal to the pressure on the bottom of the other two tanks." _True_ "The force due to the water on the bottom of tank A is .... the weight of the water in the tank" _Equal to_
