In a model AC generator, a 503 turn rectangular coil 5.0 cm by 21 cm rotates at 120 rev/min in a uniform magnetic field of 0.59 T.
(a) What is the maximum emf induced in the coil?
__________V
(b) What is the instantaneous value of the emf in the coil at t = (pi/38) s? Assume that the emf is zero at t = 0.
___________V
(c) What is the smallest value of t for which the emf will have its maximum value?
__________s
Heat is another word for thermal energy. Dissimilar materials at the same temperature can contain different amounts of heat.
