Part B; Questions 6-8:  For this part show your work, steps and calculations. Just an answer that results from a multi step operation on your calculator is NOT sufficient. Solution lacking detailed steps won’t be fully credited.

6. A circular conducting loop with area A = 0.092 m2 is placed in a uniform magnetic field of 0.44 T with the plane of the loop perpendicular to the magnetic field as shown. The loop is rotated 180o about the axis in 0.25 s.

(a) What is the average induced emf in the loop during this rotation?

(b) What is the rate of change of the magnetic flux that created the induced emf through the loop?

7. A series combination of a resistor R and a capacitor of a capacitance c = 0.40 mF is connected to 120 Vrms, 60 Hz ac source. Given the rms current in the circuit is 5.00 A,

(a) determine the value of R.

(b) determine the rms current going through the capacitor.

8. R-L-C series circuit. The rms voltage across the resistor is 30.0 V, across the capacitor is 90.0 V, and across the inductor is 50 V, If the current through the resistor is 5.00 A, find

(a) the impedance of the circuit.

(b) the capacitive reactance of the capacitor.

(c) the inductive reactance of the coil.
