action and reaction are equal in magnitudeand opposite in direction then why do they not balance each other ?​

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

Acircuit contain a 5-ohm, a3-ohm, and an 8-ohm resistor in series. what is the total resistance of the circuit ?
