An inductor in the form of an air-core solenoid contains 191 turns, is of length 17.9 cm, and has a cross-sectional area of 1.2 cm^2 . the permeability of free space is 1.25664 × 10^−6 n/a^2 . what is the magnitude of the uniform rate of change in current through the inductor that induces an emf of 205 µv? answer in units of a/s.

Why should seat belts not be mandatory quick plz

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.
