I really don’t know . Dey said I gotta so low sum before I ask another question
By definition we have that the energy at the top of the ramp is equal to the energy at the bottom of the ramp. This is due to the principle of energy conservation.
We have then:

The energy at the top is only potential energy:

Where,
- <em>m: mass
</em>
- <em>g: acceleration of gravity
</em>
- <em>h: vertical height of the ramp
</em>
The energy when it falls is transformed into kinetic energy and therefore:

Where,
- <em>v: object speed.
</em>
Therefore we have:

Answer:
The potential energy is transformed into kinetic energy.

When a roller coster goes down hill all its stored energy is bieng used as electricity is bieng converted into energy (moving)
Answer:
It is a parallel connection
Explanation:
In parallel connection the
Cell is not easily used up because the cells share the total current generated together with all bulbs.
But a major problem is the bulbs must not be left together undisconnected to avoid exhaustion arising from short fall in the strength of one cell as this bounds to affect others
The last one, Kinetic energy bc it is taking them to school
