Astudent is experimenting with a battery, three identical light bulbs, and some wire. first, she creates a circuit with the light bulbs in series, and next, in parallel, and observes the brightnesses of the bulbs for each circuit. she decides to analyze the total power from the battery for both circuits, assuming that the battery emf is and the three bulbs each have constant resistance r. (for all symbolic answers, use the following as necessary: r and ℰ for .

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?
