Ga circular coil of radius cm contains 135 loops and its plane is positioned perpendicular to a uniform magnetic field, it is quickly and uniformly pulled from the field to a region where the b-field drops abruptly to zero. it takes 0.10 s for the whole coil to reach the field-free region. how much power is dissipated in the coil if its resistance is 170 ω?
