Two coils of wire are placed close together. Initially, a current of 1.12 A exists in one of the coils, but there is no current in the other. The current is then switched off in a time of 2.37 x 10-2 s. During this time, the average emf induced in the other coil is 1.24 V. What is the mutual inductance of the two-coil system

Ответ:
then to find out how far he is moving for 15 seconds multiply 8.333 x 15= 125
8.333x= 360
divide 360 by 8.33 which equals 43.2
and the answer to "C" is yes because it took 43.2 sevonds
