Sagot :
The force of the water on Dam #2 is 8 times than the force on Dam #1. Hence, option (c) is correct.
What is force?
The definition of force in physics is: The push or pull on a massed object changes its velocity.
Let the height and wide of dam #1 is H and d respectively.
Then, the height and wide of dam #2 is 2H and 2d respectively.
Average force acting on the dam #1 = 1/2( pressure at the surface of the lake + pressure at the bottom of the lake) × area of the dam#1
= 1/2(0 + Hρg)×Hd
= H²ρgd/2
Average force acting on the dam #2 = 1/2( pressure at the surface of the lake + pressure at the bottom of the lake) × area of the dam#2
= 1/2(0 + 2Hρg)×2H × 2d
= 8H²ρgd/2
Hence, the force of the water on Dam #2 is 8 times than that on Dam #1.

Your question is incomplete, but most probably full question was:
Dams at two different locations are needed to form a lake. when the lake is filled, the water level will be at the top of both dams. The Dam #2 is twice as high and twice as wide as Dam #1. How much greater is the force of the water on Dam #2 than the force on Dam #1? (Ignore atmospheric pressure; it is pushing on both sides of the dams.) A. 2 B. 4 C. 8 D. 16
