Answer:
A. alternating current
Explanation:
An alternating current is that which changes polarity in a periodic manner. It is generated when a conductor cuts or breaks magnetic field lines in such a way that it periodically alternates or switches its direction of motion or position between the north and south poles of the magnetic field.
The switching of the direction of motion makes the polarity of the induced current to change in a manner that corresponds to the motion of the conductor. This is what generates an alternation current (a.c)
Answer:
(A)
Explanation:
We know , electric potential energy between two charge particles of charges "q" and "Q" respectively is given by kqQ/r where r is the distance between them.
Since the two charged particles are moving apart, the distance between them (r) increases and thus electrical potential energy decreases.
The prefix your looking for is centi as in centimeter. I got this answer on google.

No, not exactly. They jiggle and tremble and vibrate a lot, but
they always basically stay in very nearly the same place.
It's like if you're allowed to go anywhere you want in your jail cell,
you wouldn't exactly call that "moving about freely".
