B(T) 2 0.1 0.3 0.5 0.8 0.9 t(s) -2 QUESTION 5 How much power is dissipated by the coil at time = 0.6 seconds? O 0.2 W O 0.4 W O 0,5 W O None of these

A segment of wire 7.4 cm long is moving at a velocity of 7.08 m/s toward a parallel (much longer) wire which carries a current of 7.55 A. At a particular instant the wire segment is 5.4 cm away from the long, current-carrying wire. What is the induced emf (voltage) between the two ends of the wire segment?     1.47E-05 V     5.88E-06 V     1.18E-05 V     1.91E-05 V

An emf is induced by rotating a 1070 turn, 20.0 cm diameter coil in the Earth's 4.95 ✕ 10−5 T magnetic field. What average emf (in V) is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0 ms?
