Calculate the approximate change in density of water in a lake at a depth of

400 \mathrm{~m}

below the surface. The density of water at the surface is

1030 \mathrm{~kg} / \mathrm{m}^3

and bulk modulus of water is

2 \times 10^9 \mathrm{~N} / \mathrm{m}^2

.

View answer and explanation

Correct option: A

2.0 \mathrm{~kg} / \mathrm{m}^3

Option A (

2.0 \mathrm{~kg} / \mathrm{m}^3

) is correct because it is the approximate change in density calculated using the bulk modulus formula.
