1. The problem statement, all variables and given/known data At a particular point in the Pacific Ocean, the density of sea water increases non-linearly with depth according to p = p_o + m*z^2 where p_o is the density at the surface, z is the depth below the surface, and m is a constant. Develop an algebraic equation for the relationship between pressure and depth. p(represents density, not pressure), P represents pressure. NB: ^ represents to the power of.... (eg z^2 is z squared) 2. Relevant equations p = p_o + m*z^z ....(1) 3. The attempt at a solution P = p_o*gz; p_o = P/gz; then From (1): p = (P/gz) + m*z^2 but p = m/v so m/v = (P/gz) + m*z^2 mgz(1/v - z^2) = P but F = mg so Fz(1/v - z^2) = P I know this is wrong but i really need help!!!
