Answer:
(a) 0.0171 V
Explanation:
A = 0.09 m^2, dB/dt = 0.190 T/s
(a) According to the law of electromagntic induction
e = dФ / dt
e = A dB / dt
e = 0.09 x 0.190 = 0.0171 V
(b)
as we know
i = e / R
we can find induced current by dividing induced emf by resistance
Let the Blaise runs for time "t" to complete the race
so the total distance he moved is given by

Now Issac runs for time t = "t - 2*60"
because it took rest for 2 minutes

now it is given that Blaise wins by 10 m distance




now the distance moved by Blaise is given by
