A wire loop has an area of 0.36 m² and a resistance of 1.5 ?. The loop lies in a horizontal plane where there is a downward-directed magnetic field of magnitude 0.015 T. The wire is pulled to one side so that it is completely out of the field after 0.20 s. For the 0.20-s period during which the loop is being pulled out of the magnetic field, find the following:

a. Find the average induced emf in the loop.

b. Find the average current induced in the loop and its direction.

c. Find the total charge passing any point in the loop.

d. Find the average power dissipated in the loop.

e. Find the total energy dissipated in the loop.
