When a compressible wave is sent towards...

When a compressible wave is sent towards bottom of sea from a stationary ship it is observed that its echo is hear after `2s`. If bulk modulus of elasticity of water is `2xx10^(9)N//m^(2)`, mean temperature of water is `4^(@)` and mean density of water is `1000kg//m^(3)`, then depth of sea will be

A

`1014m`

B

`1414m`

C

`2828m`

D

`3000m`

Text Solution

Verified by Experts

The correct Answer is:
B
`(2d)/(v_(s))=2`
`rArrd=v_(s)`
`rArr d=sqrt((B)/(rho))=sqrt((2xx10^(9))/(1000))=1414m`
