The rotating loop in an ac generator is a square 13.0 cm on a side. It is rotated at 40.0 Hz in a uniform field of 0.800 T. Calculate the following quantities as functions of time t, where t is in seconds. (a) the flux through the loop ΦB = mT⋅m2 (b) the emf induced in the loop ε = V (c) the current induced in the loop for a loop resistance of 2.00 Ω I = A (d) the power delivered to the loop P = W (e) the torque that must be exerted to rotate the loop τ = mN⋅m
