The average depth of indian Ocean is about 3000 m. The fractional compression, `(triangleV)/(V)` of water at the bottom of the ocean is (Given Bulk modulus of the water `=2.2xx10^9Nm^-2` and `g=10ms^-2`)

Explanation

The pressure exerted by a 3000 m column of water on the bottom layer
`p=hrho" g"=3000" m"xx1000" kg m"^(-3)xx10"m s"^(-2)`
`=3xx10^(7)" kg m"^(-1)" s"^(-2)`
`=3xx10^(7)"N m"^(-2)`
Fractional compression `DeltaV//V`, is
`DeltaV//V=" stress/B"=(3xx10^(7)" N m"^(-2))//(2.2xx10^(9)" N m"^(-2))`
`=1.36xx10^(-2)` or `1.36%`
