<span>. An object at an elevated position will have stored energy while not in motion potential energy is given by (m*h*g) or
(weight*h) due to gravity.
so it is
potential energy only
socorrec toption is
B
hope it helps </span>
Answer: 330 m
Explanation:
The speed of sound 
is defined as the distance traveled by the sound wave

is the distance between the person and the hill
So, we have to find :
Finally:
I hope this helps. it was right when i took the test.
Its total mechanical energy is <em>2,000 J</em>.
We don't have enough information to say anything about its heat energy, its chemical energy, or the energy due to any electrical charge it may be carrying or any magnetic field it may have.
