Answer:
D. has no overall force acting on it.
Explanation:
Why?
Because in a straight line at the constant speed means the car moving in the same velocity, which is not acceleration neither deceleration, and it cannot be on a downhill slope. So the correct answer is
<h3>→ D. has no overall force acting on it.</h3>
Lots. there are just so many. maybe a million since they are so tiny and they make up everything
Explanation:
We will calculate the gravitational potential energy as follows.
=
= 1164000 J
or, = 1164 kJ (as 1 kJ = 1000 J)
Now, we will calculate the change in potential energy as follows.
=
=
= -873000 J
or, = -873 kJ
Thus, we can conclude that change in gravitational potential energy is -873 kJ.

<span>The correct answer is b. An earthquake occurs. Basically, the earth's crust can't deal with the stress and strain so an earthquake occurs. That's why earthquakes are common where tectonic plates are unstable like the pacific area and the Western part of US. Places like Japan and San Francisco are famous for having earthquakes.</span>
