Answer to Question #84466 in Molecular Physics | Thermodynamics for Ra

Question

The elastic stiffness constants in MgO are as follows:
C_11=2.86×10^11Nm^(-2); C_12=0.87×10^11Nm^(-2); and C_44=1.48×10^11Nm^(-2);
Calculate the velocity of propagation of the longitudinal and transverse elastic waves along the [110] direction in the MgO crystal. Density of MgO is 3.58gcm^(-3)
