Answer :
Given that the pressure one experiences descending the depths of the ocean is linear. The pressure is 15 pounds per square inch on the surface of the water and the pressure is 35 pounds per square inch 45 feet below the surface.
We have to find the equation giving the relationship between pressure p and depth d.b. We have to find the pressure 10,800 feet below the surface of the water. Therefore, the equation that gives the relationship between the pressure and depth is of the formp = md + c, where p is the pressure, d is the depth, m is the slope of the line, and c is the y-intercept.
We know that at a depth of 45 feet below the surface, the pressure is 35 pounds per square inch, and at the surface, the pressure is 15 pounds per square inch.Substituting these values in the equation above Substituting this value in the equation, p = (4/3)d + 15 We have to find the pressure at 10,800 feet below the surface of the water .
