Answer:
Particles in a water wave exchange kinetic energy for potential energy. When particles in water become part of a wave, they start to move up or down. This means that kinetic energy (energy of movement) has been transferred to them

Answer: For ideal machine efficiency = 1. Hence M.A = V. R. The V. R of an ideal machine and the practical machine is a constant or is the same for both
I believe the answer would be zero because the q1 and q2 are equal on opposite sides and it

Mar 28, 2011 · The Hoover Dam generates
electricity using hydropower. Hydropower is the power generated by
moving water. Dams are often built on a large river, so the water falls
down from the top of the dam. At the bottom of the dam, the water
rotates a large turbine

<h3><u>Answer;</u></h3>
just before it reaches the ground
<h3><u>Explanation;</u></h3>
- Kinetic energy is the energy possessed by a body or an object in motion.
- <em><u>Kinetic energy is given by 1/2mv², where m is the mass of the object and V is the velocity of the body. Thus, kinetic energy depends on the velocity of the body if mass is kept constant.</u></em>
- <em><u>As soon as the ball leaves the racket it has more kinetic energy and zero potential energy. As it moves up its velocity decreases, and thus the kinetic energy is being converted to kinetic energy up to maximum height reached where kinetic energy will be zero since the velocity is zero.</u></em>
- <em><u>When the ball is going down the potential energy will be converted to kinetic energy up to a point just before it hits the ground, where kinetic energy is maximum since the velocity of the ball is maximum, due to gravitational acceleration.</u></em>
