Q. Two gerbils run in place with a linear speed of 0.587 m/s on an exercise wheel that is shaped like a hoop. Calculate the angular momentum of the system if each gerbil has a mass of 0.275 kg and the exercise wheel has a radius of 9.22 cm and a mass of 4.89 g.

Q. What mass (in grams) of steam at 100°C must be mixed with 377 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 58.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg, and the latent heat of vaporization is 2256 kJ/kg.
