In each of two coils the rate of change of the magnetic flux in a single loop is the same. The emf induced in coil 1, which has 228 loops, is 3.13 V. The emf induced in coil 2 is 4.16 V. How many loops does coil 2 have

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
