Document Summary
Physics lecture questions: the following property does (is) not characterize (an assumption) an ideal stationary fluid, incompressible, stationary when in mechanical equilibrium, density increases linearly with depth, deformable, propensity toward mechanical equilibrium. Answer: c density is constant according to the assumptions. Answer: e: we apply pascal"s law to an unknown fluid for which we know that its pressure rises to. 1. 2 atm at a depth of 1. 0 m below the surface. At what depth does the pressure rise to 2. 4 atm: 1. 0m, 2. 0m, 5. 0m, 7. 0m, 10. 0m. 1. 2 atm = 1 atm +pg1. 0m = 0. 2atm. 1. 4atm = pgyo: when reporting blood pressure values, we use, absolute pressures, pressure in si units, pressures relative to the heart, gauge pressure. Answer: d: name an animal that will be affected more than humans, mouse, blue jay, cat, horse, giraffe. Answer: e: sharks have to actively swim all their life to avoid sinking to the bottom of the sea.
