2. I
Which is true of a pot and a penny
with equal temperatures?
A they have the same thermal energy
B they are both gaining thermal energy
© the penny has more thermal energy
D the pot has more thermal energy

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?
