Aflat circular loop of wire of radius 0.50 m that is carrying a 2.0-a current is in a uniform magnetic field of 0.30 t. what is the magnitude of the magnetic torque on the loop when the plane of its area is perpendicular to the magnetic field?

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
