A heavy ball with a weight of 110 N is hung from the ceiling of a lecture hall on a 4.4-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.3 m/s as it passes through the lowest point. What is the tension in the rope at that point?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
