A flat circular coil by 106 turns, a radius of 2.43 x10-2 m, and a resistance of 0.328 Ω is exposed to an external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field is changing at a rate of ΔB/Δt = 0.772T/s, thus inducing a current in the coil. Discover the magnitude of the magnetic field at the center of the coil that is produced by the induced current.
What is the centripetal acceleration of an object on the Earth's equator owing to the rotation of the Earth? What would the period of rotation (in hours = h) of the Earth have to be for objects on the equator to have a centripetal acceleration equ..
