Does it mean as much as you thought it would ?
The potential energy of a mass is given by the formula:
Where m is the mass, g is the gravity acceleration and h is the height.
Since the mass and gravity will be constant, for half the potential energy, we have:
So the box will have half the potential energy at half the height of the ramp.
Answer:
Ohm's law is not applicable to semi-conductors and insulators.
Explanation:
Is this what you want?
This is A, true, because no matter what you do, it will have a reaction that happens.
