A-6: A-7: A-B: A-9: Lucy is going skin diving to see coral off the coast ofMexico in sea water with a density of 1025 kg/m3. a) How great is the pressure pushing on Lucy at a depth of 20.0 m? b) How will the pressure change if Lucy swims deeper? A water tower sits on the top of a hill and supplies water to the citizens below. The difference in pressure between the water tower and the Daileys' house is 1.1 x 105 Pa, while the difference in pressure between the tower and the Stearns' house is 3.2 X 105 Pa. a) Which house sits at a higher elevation, the Daileys' or the Steam\"! b) What is the difference in elevation between the two houses? Eileen is oating on her back in the beautiful blue Caribbean during her spring vacation. If Eileen's density is 980 kg/m3 and she has a volume of 0.060 1113, what is the buoyant force that supports her in the sea water of density 1025 kg/m3? While swimming in her backyard pool, Nicole attempts to hold a 0.9mm? inner tube completely submerged under the water. a) What buoyant force will be exerted on the inner tube as Nicole attempts to force it under the water? b) When Nicole lets go of the inner tube, it pops up to the surface with a force of 8990. N. What is the weight of the inner tube
