Let us assume that the density of seawater is similar to
ordinary water that is:
density ρ = 1000 kg / m^3
Then we can calculate the hydraulic pressure using the
formula:
P = ρ g h
P = (1000 kg / m^3) * 9.81 m/s^2 * 9,500 m
<span>P = 93,195,000 Pascal</span>
Momentum = (mass) x (speed)
Divide each side by (speed): Mass = (momentum) / speed
Mass = (45,000 kg-m/s) / (30 m/s) =
1,500 kg .
Answer:
to the left.
Explanation:
We can use the equation where v is the velocity at time t and the velocity at . Since we want the acceleration we write this equation as:
Considering the <em>direction to the right as the positive one</em>, we have at , and at , so we substitute:
Where the minus sign indicates it is directed to the left.
100J/20s= 5 joules per second
Or 5 watts
