Saturn’s moon Titan has a mass of 1.35 × 1023 kg. If Titan is 1.19 × 106 km from Saturn, and Saturn’s mass is 5.86 × 1026 kg, what is the gravitational force between Saturn and its moon?

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.
