MC __________ Prob 9 __________ Raw Score __________ Percentage __________% MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question Figure 29.1 1) In Fig. 29.1, a wire and a 10 - Ω resistor are used to form a circuit in the shape of a square, 20 cm by 20 cm. A uniform but nonsteady magnetic field is directed into the plane of the circuit. The magnitude of the magnetic field is decreased from 1.50 T to 0.50 T in a time interval of 32 ms. The average induced current and its direction through the resistor, in this time interval, are closest to: A) 75 mA, from a to b B) 75 mA, from b to a C) 190 mA, from a to b D) 130 mA, from b to a E) 130 mA, from a to b 1) A-1
