A planar coil of wire consists of a single turn. The normal to this coil is parallel to the uniform and constant (in time) magnetic field of 1.3 T. An emf that consists of a magnitude of 2.9 V is induced in this coil because the coil's area A is shrinking. Determine the magnitude of A/ t, which is the rate (in m^2/s) at which the area changes?
