Explanation / Answer

1)

N = 29

radius , r = 1.06/2 = 0.503 m

magnetic field , B = 54 uT

time , t = 0.20 s

average induced emf = change in magnetic flux/time taken

average induced emf = 29 * pi * 0.503^2 * (54 *10^-6 - (54 *10^-6))/0.20

average induced emf = 0.0124 V

the average induced emf in the loop is 0.0124 V
