In 1993 the radius of hurricane emily was about 350 km/h. the wind speed near the center ("eye") of the hurricane, whose radius was about 30 km, reached about 200 km/h. as air swirled in from the rim of the hurricane toward the eye, its angular momentum remained roughly constant. a) estimate the wind speed at the rim of the hurricane. b) estimate the pressure difference at the earth's surface between the eye and the rim (hint: the density of air (1 atm, 20 c) is 1.20 kg/m^3 .) c) where is the pressure greater? d) if the kinetic energy of the swirling air in the eye could be converted completely to gravitational potential energy, how high would the air go?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
