A diver is on a board 1.80 m above
Virty [35]

Answer:

v = 6.95 m/s

Explanation:

Given that,

A diver is on a board 1.80 m above  the water, s = 1.8 m

The initial speed of the diver, u = 3.62 m/s

Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :

v^2-u^2=2gs\\\\v=\sqrt{u^2+2gs} \\\\v=\sqrt{(3.62)^2+2(9.8)(1.8)} \\\\v=6.95\ m/s

So, she will hit the water with a speed of 6.95 m/s.

3. Learn: Energy is transferred along food chains, however, the amount of available energy decreases from one
Zolol [24]

''Energy is destroyed because animals are higher levels do not need as much energy'' is not the valid reason.

<h3>What is respiration?</h3>

Respiration is the cellular process of releasing energy from food. Some of the energy released is used to produce ATP. 90 percent of energy is lost as heat energy whereas 10 percent energy is transferred to other trophic levels.

So we can conclude that ''Energy is destroyed because animals are higher levels do not need as much energy'' is not the valid reason.
