Question

The three tanks are filled with water to an equal depth. All the tanks have an equal height. Tank A has the middle surface area at the bottom, Tank C the greatest and Tank B the least. For each of the following statements, select the correct option from the pull-down menu. (True, False, Greater than, Less than, Equal) The force due to the water on the bottom of Tank C is __________ the force of the water in the tank. 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. The pressure at the bottom of Tank C is _______ the pressure at the bottom of Tank B. The pressure exerted at the bottom of Tank B is equal to the other two tanks. The water in Tank B exerts a downward force on the sides of the tank.

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)
