The only common property is that both of those things are comprised of H2O.

A. Closed. This is because the circuit can flow without interruption.
Hi there!
We can begin by deriving the equation for how long the ball takes to reach the bottom of the cliff.
There is NO initial vertical velocity, so:
Rearrange to solve for time:
Plug in the given height and acceleration due to gravity (g ≈ 9.8 m/s²)
Now, use the following for finding the HORIZONTAL distance using its horizontal velocity:
Answer:
8.6*10^5N
Explanation:
Pressure of the water = density of water * height of the water * acceleration due to gravity
Pressure of water = 1000*9.81*(2.5 + 8.50)
Pressure of the water = 107910 = 1.08*10^5
And Pressure = force / A
Force = Pressure * A(surface area of the container)
Force = 1.08*10^5 * 8 = 863280 = 8.6*10^5N
