A 13cm×13cm square loop lies in the xy-plane. The magnetic field in this region of space is B=(0.30ti+0.46t2k)T, where t is in s. What is the E induced in the loop at t = 0.5s? What is the E induced in the loop at t = 1.0s?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
