(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A.

B.

C.

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 least and tank C the middle.

(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 A is ... the force exerted by the water on the bottom of tank C

B) The pressure at the bottom of tank A is ... the pressure at the bottom of tank B

C) The water in tank B exerts an upward force on the sides of the tank.

D) The force due to the water on the bottom of tank A is .... the weight of the water in the tank.

E) The pressure exerted on the bottom of tank B is smaller than for the other tanks.

2. Relevant equations

F= p*A

p = density*g*d

3. The attempt at a solution

I hate these types of problems because I know I'll have all but one wrong...

A: Greater Than, A has a larger surface area on the bottom, and thus has a larger force since pressure is the same because they have the same depth.

B: Equal To, pressure is just related to depth. Since they all have the same depth, the pressures are equal.

C: False, water does not come in contact vertically with the tank.

D: Equal To, even though the wall is exerting some force down on the water the water is exerting some force up on the walls.

E: False, the pressure is the same because all the containers are filled to the same height with the same liquid.

I greatly appreciate any help.
