<h2>Answer:</h2>
<u>The correct answer is </u><u>(A) The chemical energy in the food is converted to mechanical energy to give the body energy to move.
</u>
<h2>Explanation:</h2>
The chemical energy in food can be converted to another form of chemical energy when it is stored as glucose or fat. The chemical energy in our food can also be converted to mechanical energy in the form of muscle movement and it provides us energy to travel and move from one place to another pace. The entire energy is not converted to mechanical though, it is also converted into heat energy.
Using the information given, gas-A is still completely unknown.

Answer:
17.86 m
Explanation:
The first step is to find the velocity of the swimmer.
Velocity, v = s/t
Velocity, v = 5 / 0.27
Velocity, v = 18.52 m/s
Then, we find the height
h = ½gt²
h = ½ * 9.8 * 0.27²
h = 4.9 * 0.0729
h = 0.36 m
Next, we apply the law of conservation of energy
mgH = mgh + ½ mv²
9.8Hm = m(9.8 * 0.36 + 0.5 * 18.52²)
9.8H = 3.528 + 171.4952
9.8H = 175.02
H = 175.02 / 9.8
H = 17.86 m
Therefore, the needed height is 17.86 m
