<span>The time it takes for one wavelength to pass a fixed point is known as PERIOD.
In fact, the period is defined as the time it takes a wave to make one complete oscillation: since the wavelength is the distance between two consecutive points of the wave with same shape, it means that the time it takes for one wavelength to pass a fixed point in space is exactly the period.</span>
That's a velocity.
It has a speed and the direction of the speed.
Answer:
5000 J
Explanation:
Given that,
Weight of Danny Diver, F = 500 N
He steps off a diving board 10 m above the water
We need to find the kinetic energy of the water with which it hits. Let its is K. It is given by :
E = mgh
Where g is acceleration due to gravity

So, he hits the water with kinetic energy of 5000 J.
Answer:
The energy of motion is called is kinetic energy.
