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.

What equation is used to calculate the weight of an object on a plant ?

If a 2 ounce coin is dropped from the top of the washington monument and has a final velocity of 300 mph (miles per hour) when it hits the ground, how much kinetic energy will it have at that time?
