You build a silly type of thermal engine that only uses isobaric and isochoric processes. it has processed at 101.3kpa and 303.9kpa, and 0.01m^3 and 0.05m^3. when the system is at its lowest pressure and volume it has a temperature of 20 c. a) what is the total work done in a cycle? b) what is the hear added in a cycle? c) what is the change in internal energy in a cycle? d) on a pv diagram note the temperature at each corner of the process.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
