It is a hot, sunny day. the outdoor temperature is 32°c (90°f), and the water temperature is 21°c (70°f). a scuba diver submerses himself while holding a balloon filled with 1.5 l of air. if the balloon shrinks to a volume of 0.5 l at a depth of 20 m, what is the pressure at this depth? (assume that the outdoor pressure is 1 atm.)

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
