Stainless steel ball bearings having a diameter of 1.5 inches are to be quenched in water at a rate of 750 per minute. the balls leave the oven at a uniform temperature of 950°c and are exposed to air at 25°c for a while before they are dropped into the water. if the temperature of the balls drops to 875°c prior to quenching, determine the rate of heat transfer from the balls to the air.

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
