Homework Statement
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.
Homework Equations
F= p*A
p = density*g*d
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.
