Question

The two main physical factors that influence the speed of a mechanical wave are _____. density and magnetism density and stiffness stiffness and magnetism density and thickness

Answer 1

Density and Stiffness

Step-by-step explanation:

The two main physical factors that influence the speed of a mechanical wave are _____.

density and magnetism

density and stiffness

stiffness and magnetism

density and thickness

Answer 2

I think the correct answer would be density and stiffness. For any wave, the speed will always be equal to the square root of a resistance over its density. The resistance can be tension, stiffness or other measures. Hope this answers the question.
