A square loop of wire of side 2.3cm and electrical resistance of 79 ohms

A square loop of wire of side 2.3cm and electrical resistance of 79 ohms is near a long straight wire that carries a current of 6.8A (upward, parallel to the wire). The long wire and the loop both lie in the plane of the page. The left side of the loop is 9.0cm away from the wire.
a) If the loop is at rest, what is the induced emf?
b) repeat if the loop is moving to the right at a constant speed of 45cm/s?
c) In (b), find the electric power dissipated in the loop and show that it is equal to the rate at which an external force, pulling the loop to keep its speed constant, does work.
