The current in the wire (blue) is directed to the left. A conducting loop (green) is in the plane of the wire. The current is increasing with time. Find the direction of current in the conducting loop, if any. Iwire 1. Counterclockwise (CCW) 2. No current 3. Clockwise (CW)

Answer8.0m;

The answer is trial 3.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
