sailing vessels can carry lead ballast such as bricks to keep the vessel properly oriented and upright in the water. Consider a vessel that takes on cargo and the crew jettisons a total of 0.500m^3 of the lead ballast into water 2000 m deep. Seawater's density is equal to 1.025g/cc while lead's bulk modulus equals to 42 GPa. Find the change in pressure at 2km depth.
