A100 gram mass of metal at 146 celsius is placed in 100 grams of cool water [cw=4.186 j/g*co] at 5 celsius. the final temperature of the mixture is 25 celsius. what is the specific heat capacity of the metal?
cool water = -[metal]
mcaδt = -[mcwδt]

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?
