Find the density of seawater at a depth where the pressure is 280 atm if the density at the surface is 1035 kg/m^3. seawater has a bulk modulus of 2.3 x 10^9 N/m^2.

Explanation:

Formula for Bulk modulus of a material is as follows.

         B =      

    (Bulk modulus = pressure × compressibility)

Hence,

                =

Therefore, we can conclude that density of seawater at a depth where the pressure is 280 atm is .

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
