Question #243921

Estimate the order of magnitude of the velocity of sound in the metal.

Expert's answer

The speed of sound can be expressed in terms of density (order of magnitude 1000) and young's modulus of metal (order of magnitude 10⁹:

"OM_v=\\sqrt\\frac{OM_E}{OM_\\rho}=\\sqrt{\\frac{10^9}{1000}}=10^3."
