Question

The three tanks above are filled with water to the same depth. All the tanks have an equal height. Tank C has the middle surface area at the bottom, tank B the greatest and tank A the least. For each of the following statements, select the correct option from the pull - down menu. The force due to the water on the bottom of tank C is .... the weight of the water in the tank. 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. The water in tank B exerts a downward force on the sides of the tank. The pressure exerted on the bottom of tank B is equal to the pressure on the bottom of the other two tanks. The pressure at the bottom of tank B is .... the pressure at the bottom of tank C. Pressure depends on the depth (times density times gravity). Force is pressure times area. Weight is density times volume times gravity. Incorrect. Tries 32 / 99 Previous Tries

Explanation / Answer

A- True (GRAVITY pulls down!!!)
B- Less (as there is more area to distribute the force to/and there is more water changing the pull of gravity)
C- Less than
D- False
E- Less than (counter-intuitive, but some of the pull of gravity is supported by the walls of tank C)
