Answer:
V = 2534.37 m/s
Explanation:
density [tex]= 2.6 g/cm^3 = 2600 kg/m^3[/tex]
young's modulus [tex]= 0.39\times 10^{11} N/m^2[/tex]
Poisson's ratio = 0.11
we know that bulk modulus is given as
[tex]\beta = \frac{E}{3(1-2\mu)}[/tex]
[tex]= \frac{0.39\times 10^{11}}{3(1-2\times 0.11)}[/tex]
[tex] = 1.67\times 10^{10}[/tex]
velocity of wave is given as
[tex]V =\sqrt{\frac{\beta}{\rho}}[/tex]
[tex]V = \sqrt{\frac{1.67\times 10^{10}}{2600}}[/tex]
V = 2534.37 m/s
