Acircular wire loop of radius r = 0.35 m and resistance r = 9.9 ω rotates about a shaft through its diameter at a constant rate of f = 5.75 hz in a uniform b = 0.41-t magnetic field directed perpendicular to the rotation axis. the plane of the loop is perpendicular to the magnetic field at time t = 0. select the correct expression for the time-dependent magnetic flux through the loop. find the value of the magnetic flux through the loop, in webers. at time t = 3.7 s. select the expression for the time-dependent emf induced in the loop based on the expression you entered in part (a).b. calculate the induced emf in the loop, in volts, at time t = 3.7 s. select the expression for the induced current in the loop based on the expression you entered in part (c). find the induced current in the loop, in amperes, at time t = 3.7 s.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
