A planar coil of wire has a single turn. The normal to this coil is parallel to a uniform and constant (in time) magnetic field of 1.4 T. An emf that has a magnitude of 2.7 V is induced in this coil because the coil's area A is shrinking. What is the magnitude of A/ t, which is the rate (in m^2/s) at which the area changes?
