Well,
When an object's velocity changes, we call it acceleration.
Acceleration: The time rate of change in an object's velocity
Free fall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. For example, when a ball is thrown up in the air, the ball's velocity is initially upward.
Answer:
H = 109.2 TJ.
Explanation:
Please see the attachment below.
I<span>n </span>direct current<span> (</span>DC), the electric charge (current<span>) only flows in one direction. Electric charge in </span>alternating current<span> (</span>AC<span>), on the other hand, changes direction periodically. The voltage in </span>AC<span> circuits also periodically reverses because the </span>current<span> changes direction.</span>
This is your perfect answer
It is flexible. Water flow can be adjusted and even conserved according to the need for power. It is safe! Compared with the use of fossil fuels and nuclear energy, hydropower is a much safer system..
