Thirty-six grams of air in a piston–cylinder assembly undergo a stirling cycle with a compression ratio of 7.5. at the beginning of the isothermal compression, the pressure and volume are 1 bar and 0.03 m3, respectively. the temperature during the isothermal expansion is 1400 k. assuming the ideal gas model and ignoring kinetic and potential energy effects, determine: (a) the net work, in kj. (b) the percent thermal efficiency. (c) the mean effective pressure, in bar.

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
