If the speed of longitudinal mechanical ...

If the speed of longitudinal mechanical waves in water is `1400m//s` then calculate the bulk modulus of elasticity of water. (given density of water is `1g//cm^(3)`)

Text Solution

Verified by Experts

Speed of longitudinal wave is
`v=sqrt((B)/(rho))`
`140000cm//s=sqrt((B)/(1))`
`impliesB=1.96xx10^(10)"dyne"//cm^(2)`
`=1.96xx10^(9)N//m^(2)`
