When the resistance decreases, the current increases.
Answer:
0.0129 V
Explanation:
The average emf induced in the coil is given by Faraday-Newmann-Lenz:
where
is the variation of magnetic flux through the coil
is the time interval
Here we have
B = 0.50 T is the strength of the magnetic field
The radius of the coil is
r = 35 cm = 0.35 m
So the area is
The initial flux through the coil is
while the final flux is zero, since the coil has been completely removed from the magnetic field region; so, the variation of magnetic flux is
and so, the average emf induced is
The total distance is 60*2-15=105 kilometers, and the total displacement is 15 kilometers east.
