The oxygen levels in a diver's body can become toxic if they dive too deep using a tank of regular air. assume that a certain individual starts experiencing undesirable effects if the gauge pressure exceeds 42.5 lb/in2. (gauge pressure is the pressure in excess of normal atmospheric pressure, which is the pressure your body tissues are used to.) in sea water, which has a density of 1.03 g/cm3, to what depth should the diver be limited? assume that =9.80 m/s2, that 1 pound is 4.448 n, and that 1 inch is 0.0254 m. (you need to know something about how diving tanks work. they have a pressure regulation system that feeds air from the high-pressure tank on the divers back into the divers mouth and respiratory system at the pressure of the water that surrounds her.)
