Question

determined by the waves energy. waves with a lot of energy have larger amplitudes than waves with little energy. imagine hitting a drum. when you hit the drum, you transfer energy to it. the energy causes the drum to vibrate. these vibrations produce a sound wave that travels through the air. if you hit the drum harder, more energy is transferred to the drum. the drums vibrations are larger, so the sound wave has larger amplitude. the drum produces a louder sound.

when energy...	amplitude...	loudness...
...decreases	...decreases

Explanation:

Step1: Analyze the relationship between energy and amplitude

From the text, when energy increases (hitting drum harder), the drum's vibrations (and thus the sound wave's amplitude) become larger. So for the first blank in the "Amplitude..." column (when energy increases), the amplitude should increase.

Step2: Analyze the relationship between amplitude and loudness

The text states that a larger amplitude (from more energy) leads to a louder sound. So when amplitude decreases (from less energy), the loudness should also decrease. For the second blank in the "Loudness..." column (when energy decreases, amplitude decreases), the loudness decreases.

Answer:

For the "Amplitude..." column (when energy increases): increases
For the "Loudness..." column (when energy decreases): decreases

(In table form, filling the blanks:

When energy...	Amplitude...	Loudness...
...decreases	...decreases	...decreases	)
