a motorist drives north for 35 minutes at 85 km/h and then stops for 15 minutes. he then continues north traveling 130km in 2h. what was his total displacement
A plot of pressure as a function of volume is known as a pV diagram. pV diagrams are often used in analyzing thermodynamic processes. Consider an ideal gas that starts in state O, as indicated in the diagram. Your task is to explain how the gas proce..
