As shown below, a wire loop is immersed in a 0.27 T B-field (the direction of the field is shown in the diagram). The loop shrinks from a radius of 63 cm to a radius of 1.4 cm and as a result a 8.5 V voltage & a 4,7 A current are induced, Determine how long the loop was changing size & the loog's resistance.
