question 1
what causes the piezoelectric effect to occur?
a. scientists use clothing to recharge ipods.
b. human hairs are rubbed against gold fibers, thus creating electricity.
c. pressure is applied to certain materials, thus creating electricity.
d. energy is captured from falling raindrops.

Explanation:

The piezoelectric effect is a phenomenon where certain materials generate an electric charge in response to applied mechanical stress (pressure). Option C directly describes this relationship between pressure on materials and electricity generation. Options A, B, and D do not relate to the fundamental cause of the piezoelectric effect.

Answer:

C. Pressure is applied to certain materials, thus creating electricity.
