Determine the absolute pressure exerted on an object submerged 1000 m below the surface of the sea, in bars. The density of seawater is 1020 kg/m3 and the acceleration of gravity is 9.7 m/s2 . The local atmospheric pressure is 0.98 bar.

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)
