Question

1. if you pluck a guitar string hard the sound waves it gives off will have _______ amplitudes.

small
large

Explanation:

The amplitude of a sound wave is related to the energy or force with which the source (in this case, the guitar string) is set into vibration. When you pluck a guitar string hard, you are imparting more energy to it. According to the properties of sound waves, a greater amount of energy input results in a larger amplitude of the resulting sound wave. A larger amplitude corresponds to a louder sound.

Answer:

B. large
