Ascientist at a space research center is doing research on near-earth objects and determining the kinetic energy of a theoretical object. a meteorite with a mass of 12 grams falls to earth. if the meteorite’s velocity is 35 kilometers/second, what is its kinetic energy?

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r
