As the water plunges, its velocity increases. Its potential energy<span> becomes kinetic</span>energy<span>. The law of conservation of </span>energy<span> states that when one form of </span>energy<span> is</span>transformed<span> to another, no </span>energy<span> is destroyed in the process. ... So the total amount of </span>energy<span> is the same before and after any </span>transformation<span>.
hope it helps

I believe that the answer to this question is the letter A!
Answer:
1471.5 Newton
10
Explanation:
Small piston area = A₁ = 2 m²
Large piston area A₂ = 20 m
m = Mass of car = 1500 kg
g = Acceleration due to gravity = 9.81 m/s²
Force
F = mg = 1500×9.81 = 14715 N
Force applied by car is 14715 N
a) Pascal's law
Force required is 1471.5 Newton
b) Mechanical advantage
Mechanical advantage is 10
1. $85047
2. $113,080
3. $ 75,820
4. $41595
The answer is A
Explanation: the conservation of matter means that the mass stays the same
