The density of water at the surface of the ocean is ρ. If the bulk modulus of water is B. what is the density of ocean water at a depth where the pressure is hp0 (where P0 is the atmospheric pressure)?
1
\(\frac{{\rho B}}{{\left( {B - h{P_0}} \right)}}\)
2
\(\frac{{\rho B}}{{\left( {B - \left( {h + 1} \right){P_0}} \right)}}\)
3
\(\frac{{\rho B}}{{1 - \frac{{\left( {h - 1} \right){P_0}}}{B}}}\)
4
\(\frac{\rho }{{1 - \frac{{\left( {h - 1} \right){P_0}}}{B}}}\)
