Please atleast answer this question 

(a) If the emf of a coil rotating in a magnetic field is zero at t= 0 and increases to its first peak at t= 0.370 ms, what is the angular velocity (in rad/s) of the coll? rad/s (b) At what time (in ms) will its next maximum occur? (Enter the time the current next reaches its most positive value.) ms (c) What is the period of the output (in ms)? ms (d) When (in s) is the output first one-fourth of its maximum? (e) When (in s) is it next one-fourth of its maximum? 5
