C Ocean water has a density of 1.03 g/cm3. On a particular day, the atmospheric pressure at the surface of the ocean is 101 kPa. How deep into the ocean would you have to dive to experience a pressure of (125 + A + B) kPa on your body? Give your answer in meters (m) and with 3 significant figures. A=0 B=10

Required information The local atmospheric pressure in Denver, Colorado (elevation 1610 m) is 83.4 kPa. Air at this pressure and at 25°C flows with a velocity of 12 m/s over a 2.5-mx 5-m flat plate. The dynamic viscosity is independent of pressure, and for air at 25°C, it is H- 1.849 10 kg/m s. The air density at 25°C 298 K and 83.4 kPa is 0.9751 kg/m3 Calculate the drag force acting on the top surface of the plate if...

The sperm whale can dive to a depth of 2250 meters. For sea water with a density of 1020 kg/m3 what is the difference in pressure at this depth as compared to the surface? Supply your answer in atmospheres" (atm), where 1 atm approximately equals 1x105 Pa. (This is an incredibly large pressure. Human bodies would be crushed. The deepest human dive recorded was around 300 m, and even then, the diver had to spend 12 hours to surface from...
