If the specific weight of a substance is 8.2 kN/m', what is its mass density? б. 7. Samantha spots buried treasure while scuba diving on her Caribbean vacation. If she must descend to a depth of 40 meters to examine the pressure, what gauge pressure will she read on her scuba equipment? 8. What is the absolute pressure exerted on the diver in the previous problem by the water and atmosphere? 9. A barber raises his customer's chair by applying a force of 150N to a hydraulic piston of area 0.01 m2. If the chair is attached to a piston of area 0.1 m², how massive a customer can the chair raise? Assume the chair itself has a mass of 5 kg.
