Please solve these 2 questions in details and explaination. Thanks so much in advance.

1 A wire loop of radius 15 cm and resistance 11 0 is located in a uniform magnetic field that changes in magnitude as given in the figure. The loop's plane is perpendicular to the magnetic field. What is the magnitude of the emf in volts induced in the loop during the time intervals (a) t = 0 to 2.0 s; (b) 2.0 s to 4.0 s; and (c) 4.0 s to t = 6.0 s? 2.0 4.0 6.0 1 (s) (a) Number Units (b) Number Units (c) Number Units In the figure, a metal rod is forced to move with constant velocity along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude B = 0.396 T points out of the page. (a) If the rails are separated by 31.2 cm and the speed of the rod is 50.3 cm/s, what is the magnitude of the emf generated in volts? (b) If the rod has a resistance of 18.4 0 and the rails and connector have negligible resistance, what is the current in amperes in the rod? (c) At what rate is energy being transferred to thermal energy? . . . (a) Number Units (b) Number Units (c) Number Units
