Aspark plug in an automobile engine consists of two metal conductors that are separated by a distance of 0.75 mm. when an electric spark jumps between them, the magnitude of the electric field is 4.7 x 107 v/m. what is the magnitude of the potential difference δv between the conductors?

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?
