Answer 2

Explanation:

The velocity of the wave differs in gases, liquids and solids. For a mechanical wave traveling through a cord, the velocity depends on the tension in that cord as well as the mass per unit length. For waves traveling in gases, the velocity depends on the density and Young's Modulus.
