An emf is induced in a conducting loop of wire 1.06 mm long as its shape is changed from square to circular. Find the average magnitude of the induced emf if the change in shape occurs in 0.165 ss and the local 0.495-TT magnetic field is perpendicular to the plane of the loop.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
