Just the exercise part please

PRACTICE IT Use the worked example above to help you solve this problem. An AC generator consists of eight turns of wire, each having area A = 0.0930 m2, with a total resistance of 10.2 N. The loop rotates in a magnetic field of 0.577 Tat a constant frequency of 61.6 Hz. (a) Find the maximum induced emf. 166.15 (b) What is the maximum induced current? 16.29 A (c) Determine the induced emf and current as functions of time. E = (166.15 v)sin(wt) %3D I = (16.29 v A)sin(wt) w = 387 (d) What maximum torque must be applied to keep the coil turning? 6.99 N.m EXERCISE HINTS: GETTING STARTED | 'M STUCK!
