Xander's friend, pablo, accelerates on his scooter at 1. 2 m/s2 using a force of 40 newtons. What is the mass of pablo and his scooter?.

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

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is
