A series RC circuit has two resistors and two capacitors. The resistors dissipate 9 W and 15 W. The capacitive powers are 18 VARs and 9 VARs. The applied voltage is 277 V. What is the circuit current

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.
