An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1960 Ý 103 seconds (about 23 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 285.0 Ý 106 m and the planet has a radius of 3.50 Ý 106 m, calculate the moon\'s radial acceleration.

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
