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...

Background: The altitude of an airplane, can be determined by measuring the air pressure at altitude. Pressure and elevation are related by AP = - pg Az equation 1 SISTORY where AP is the change in pressure from the ground to the elevation, g is the local gravity constant of 9.81 m/s2. p is the average air density of 1.15 kg/m (assumed constant for this problem), and Az is the change in elevation in meters. UN 0. The local surface...

A diver is located 63 m below the surface of the ocean (the density of seawater is 1025 kg/m3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the buoy is inflated to 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

A spherical balloon has a radius of 7.65 m and is filled with helium. The density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. The skin and structure of the balloon has a mass of 930 kg . Neglect the buoyant force on the cargo volume itself. Determine the largest mass of cargo the balloon can lift.

A balloon filled with Helium (M=4g/mol) has diameter of .5m at sea level. For this problem, we'll assume a balloon can expand or contract when the outside pressure decreases or increases, so that internal pressure is always equal to the outside pressure. A) when the balloon is immersed in water to a depth of 1.5m, what is the new diameter? B) If the same balloon is released, and floats up to an elevation of 1500m (rising through air with constant...
