The pressure of a medium is changed from 1.01 xx 10^(5) Pa to 1.165 xx 10^(5) Pa and change in volume is 10% keeping temperature constant. The Bulle modulus of the medium is:

Answer»

`204.8xx10^(5)Pa`
`51.2xx10^(5)Pa`
`102.4xx10^(5)Pa`
`1.55xx10^(5)Pa`

Solution :BULK MODULUS
`K=(DeltaP)/((DELTAV)/V)=((1.165xx10^(5)-1.01xx10^(5)))/(1//10)`
`=1.55xx10^(5)` pascal
`therefore` CORRECT choice is (d).
