Aballoon has an initial radius of 0.075 m. a circle is painted on the balloon using silver metal paint. when the paint dries, the circle is a very good electrical conductor. with the balloon oriented such that a 1.5-t magnetic field is oriented perpendicular to the plane of the circle, air is blown into the balloon so that it expands uniformly. the silver circle expands to a radius 0.125 m in 1.5 s. determine the induced emf for this silver circle during this period of expansion.
