Two paper sacks, each containing 10 potatoes of exactly equal mass, are hung a certain distance apart. Which of the following actions would DOUBLE the gravitational force between the sacks? moving 10 potatoes from one sack to the other adding 10 potatoes of the same mass to each of the paper sacks adding 10 potatoes of the same mass to only one sack moving 5 potatoes from one sack to the other

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
