A37 g ice cube at -39°c is placed in a lake whose temperature is 35°c. calculate the change in entropy of the cube-lake system as the ice cube comes to thermal equilibrium with the lake. the specific heat of ice is 2220 j/kg·k. (hint: will the ice cube affect the temperature of the lake? )

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?
