What is a example of a subatomic particle

How much work does the charge escalator do to move 2.30 μc of charge from the negative terminal to the positive terminal of a 3.00 v battery?

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.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
