Check All That Apply U The pressure is lower at higher elevations. As a result, the difference between the blood pressure in the veins and the air pressure outside Increases. This pressure Imbalance may cause some thin-walled velns such as the ones in the nose to burst, causing bleeding. The shortness of breath is caused by the exhaustion of reaching high altitudes. The shortness of breath is caused by the lower r density at higher elevations and thus lower amount of oxygen per unit volume. Climbing high altitudes often involves trekking through rough terrain. Therefore, nose bleeding and shortness of breath occur due to fatigue.

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC.  Assume that no gas escapes from the balloon during the flight.  What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

Because of a break in a buried oil storage tank, ground water has leaked into the tank to the depth L'= 2 ft. The densities of the water and oil are, respectively, 62 and 55, each in Ib/ft3. Standpipe open to atmosphere Oil L' Water Determine the pressure at the oil-water interface and at the bottom of the tank, each in Ibf/in². (gage). Assume L = 17 ft. Let g = 32.2 ft/s?. Determine the pressure at the oil-water interface, in Ibf/in?. (gage). Palgage) = Ibf/in?.

Help me please. Thank you

1. A pressure gauge attached to a pipe is reading 1.34 m of Hg at a place where the atmospheric pressure is 10.33 m of water.

The flow velocity is not changing with time but changing with spaceb. The flow velocity is changing with both time and spacec. The flow velocity is changing with time but not changing with spaced. The flow velocity is not changing with both time and space   3. The below figure shows a pipe with a circular cross section of diameter D mm on the left end and a square cross section with side D mm on the right end. Mercury enters the left end with a velocity 1 cm/s and leaves the right end with a velocity V2. Find V2 (neglect losses in the pipe).a. Cannot be find since length is not givenb.
