a traffic light of 80n hangs from the midpoint of a 30-meter cable lying between two
posts find the tension in each segment of the cable if it forms an angle of 4 ° to the
horizontal.

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.
