Answer 1

Answer:

1. The nature of sound waves in air is longitudinal waves.

2. length, tension, density and diameter

Explanation:

here's your answer

Answer 2

Answer:

1 - The nature of the sound wave is Longitudinal wave

2 - The factors on which frequency of sound produced by a string instrument depends on the four properties of the string that affect its frequency are length, diameter, tension, and density. These properties are described below: When the length of a string is changed, it will vibrate with a different frequency. Shorter strings have higher frequency and therefore higher pitch.
