a bell is rung. what best describes the density of air around the bell?\nthe air density does not change.\nthe air density increases and then returns to normal levels.\nthe air density decreases and then returns to normal levels.\nthe air density increases and decreases repeatedly before returning to normal.

a bell is rung. what best describes the density of air around the bell?\nthe air density does not change.\nthe air density increases and then returns to normal levels.\nthe air density decreases and then returns to normal levels.\nthe air density increases and decreases repeatedly before returning to normal.

Answer

Brief Explanations:

When a bell is rung, it vibrates and causes the air particles around it to vibrate. This creates a sound wave which consists of compressions (areas of increased air - density) and rarefactions (areas of decreased air - density). As the sound wave propagates away from the bell, the air density increases and decreases repeatedly before returning to normal once the sound wave has passed.

Answer:

The air density increases and decreases repeatedly before returning to normal.
