A circular loop of wire with a radius of 4.0 cm is in a uniform magnetic field of magnitude 0.064 T. The plane of the loop is perpendicular to the direction of the magnetic field. In a time interval of 0.46 s, the magnetic field changes to the opposite direction with a magnitude of 0.043 T. What is the magnitude of the average emf induced in the loop

What ia the energy of an object because of its potential and kinetic energies
