Question

Pressure and Depth At the surface of the ocean the water
pressure is the same as the air pressure above the water,
15 lb/in2
. Below the surface the water pressure increases by
4.34 lb/in2
for every 10 ft of descent.
(a) Find an equation for the relationship between pressure
and depth below the ocean surface.
(b) Sketch a graph of this linear equation.
(c) What do the slope and y-intercept of the graph represent?
(d) At what depth is the pressure 100 lb/in2
?
