Answer:
<h2>The answer is 1376 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 8 × 10 × 17.2
We have the final answer as
<h3>1376 J</h3>

1). (c). The heat from deep in the Earth is the renewable resource.
2). (c). The natural gas is the non-renewable resource.
3). (d). The energy from the sun, collected with solar panels, is the renewable resource.
4). (b). The energy in the flow of water through the dam is the renewable resource. If you analyze it in detail, it turns out to be solar energy.
Answer: 3750 m
Explanation:
1) You can find in the literature or internet that the speed of sound in the ocean is about 1500 m/s.
2) Then, you can find the distance travel by the sound wave in 5.0s with the equation distance = speed × time
⇒ distance = 1500m/s × 5.0 s = 7500 m
3) That sound went down until the ocean floor below and cameback all the way until the sailor heard it.
Then, the deep of the ocean fllor is half that distance:
deep = 7500m / 2 = 3750m
