Ao 2.92 x 10-2 BO 2 FO DO 6.87 x 10 EO 13 x 10 GO 1.62 x 10 H 2.15 x 10 3 pt Complete the following sentence: above different During the stretching process described at 20 AO current flows in different directions stages of the process. counter clockwise. current flows CO no current flows DO current flows clockwise

Explanation / Answer

e = dphi/dt

phi = BA

A = pi*r^2

A = 13.9 cm = 0.139 m

A = 0.0607 m^2

B = 0.400 T

t = 113 ms = 113 x 10^-3 s

e = 0.400 * (0.0607/113x10^-3)

e = 2.15 x 10^-1 V

part b )

current flows in different direction at different stages of the process
