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 water in tank B exerts a downward force on the sides of the tank.
B) The pressure exerted on the bottom of tank A is greater than for the other tanks.
C) 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
D) The pressure at the bottom of tank B is ... the pressure at the bottom of tank C
E) The force due to the water on the bottom of tank B is .... the weight of the water in the tank
I thought TFLEE, but that's wrong
How can water exert a downward force on the sides of Tank A?
you mean tank b?
Hang on, I misread.
second question, is T or F. Redo it.
Nope, still wrong :(
To answer these questions, let's analyze the properties of fluids and the concept of pressure.
1) A) The water in tank B exerts a downward force on the sides of the tank. (T-True)
Explanation: In a fluid, such as water, the pressure and forces exerted are transmitted equally in all directions. This means that the water in tank B not only exerts an upward force on the bottom of the tank but also exerts an equal downward force on the sides of the tank, due to the transmission of pressure.
2) B) The pressure exerted on the bottom of tank A is greater than for the other tanks. (F-False)
Explanation: The pressure exerted at the bottom of a fluid depends on the depth and the density of the fluid. In this case, all the tanks are filled with water to an equal depth and have the same height. Since the depth is the same, the pressure exerted at the bottom of each tank is equal.
3) C) 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. (G-Greater than)
Explanation: The force exerted by the water on the bottom of a tank depends on the pressure at the bottom of the tank, which is determined by the depth and density of the fluid. Since the tanks have the same depth but different surface areas at the bottoms, the tank with the greatest surface area (tank A) will have a greater force exerted on its bottom compared to tank B.
4) D) The pressure at the bottom of tank B is... the pressure at the bottom of tank C. (E-Equal to)
Explanation: Since both tank B and tank C have the same depth and are filled with the same fluid (water), the pressure at the bottom of these tanks will be equal. This is because the pressure depends only on the depth and density of the fluid, which are the same in this case.
5) E) The force due to the water on the bottom of tank B is... the weight of the water in the tank. (E-Equal to)
Explanation: The force exerted by the water on the bottom of a tank is equal to the weight of the water. This is because the weight of the water is equal to the force exerted due to gravity. Therefore, the force due to the water on the bottom of tank B is equal to the weight of the water in the tank.
