Answer:
current forms when electromagnetic waves strike a semiconductor, removing some of its electrons.
Explanation:
Answer:
You can change the momentum of an object by giving the object more force or less force.
Explanation:
Think about a ball. It is going slow, you push it and you give it more momentum.
The electric potential energy of the charge is equal to the potential at the location of the charge, V, times the charge, q:

The potential is given by the magnitude of the electric field, E, times the distance, d:

So we have

(1)
However, the electric field is equal to the electrical force F divided by the charge q:

Therefore (1) becomes

And if we use the data of the problem, we can calculate the electrical potential energy of the charge:
