Question

<div id="MathJax_Message"></div><p>7. [2pt] 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 middle and tank C the least. (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 C exerts a downward force on the sides of the tank. B) The pressure at the bottom of tank A is ... the pressure at the bottom of tank C C) The force exerted by the water on the bottom of tank C is ... the force exerted by the water on the bottom of tank B D) The force due to the water on the bottom of tank C is .... the weight of the water in the tank. E) The pressure exerted on the bottom of tank C is smaller than for the other tanks.</p>

Explanation / Answer

here , for same height

pressure at the bottom is

P = p * g * h

A) as the area is grestest for C , the force is maximum for C ,

greater than - G

B)

False,

water applies an upward force

c)

pressure in all containers is equal

EQUAL

d)
False,

pressure in all containers is equal

e)

air pressure at the surface of all containers is equal

Hence , EQUAl
