Which change will increase the speed of a sound wave traveling in a solid aluminum rod? changing the rod from a solid to a liquid changing the rod from a solid to a gas decreasing the temperature of the rod increasing the temperature of the rod

Respuesta :

Answer:

increasing the temperature of the rod

Explanation:

Sound wave is a longitudinal wave and its speed in a solid rod is given by the formula

[tex]v = \sqrt{\frac{Y}{\rho}}[/tex]

here we know that

Y = young's modulus

[tex]\rho[/tex] = density of the medium

so as we increase the temperature of rod the density of the rod will decrease while the elasticity will remain same

So on increasing the temperature we can say that speed will increase due to decrease in the density
