Covers 18.1-18.5 Air Bubble From the Deep 19:07, trigonometry, numeric, > 1 min, nor- mal. 001 An air bubble originating from a under-water diver has a radius of 5 mm at some depth h . When the bubble reaches the surface of the water, it has a radius of 7 mm. The acceleration of gravity is 9 . 8 m / s 2 . Assuming the temperature of the air in the bubble remains constant, determine the depth h of the diver. Answer in units of m. 002 Determine the absolute pressure at this depth. Answer in units of kPa. Helium in Piston 19:07, trigonometry, numeric, > 1 min, nor- mal. 003 Pure helium gas is admitted into a tank con- taining a movable piston. The initial vol- ume, pressure, and temperature of the gas are . 015 m 3 , 200 kPa, and 300 K....
