Which event causes the formation of the electric current produced by the photoelectric effect?
A. Electrons flow in waves from one atom to another when light
strikes them.
B. The waves of light cause electrons to flow in different directions
within an atom.
o
C. Electrons are knocked off the surface that the light strikes by
"particles" of light
D. Electrons are particles, so they flow through the air from a light
bulb to a metal surface.

C

Explanation:

Light with energy above a certain point can be used to knock electrons loose, freeing them from a solid metal surface, according to Scientific American.

photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

i believe the answer is electric potential.
