A friend is running clockwise at a constant speed on a circular track. At the instant your friend is located due west of you, their velocity is in the direction pointing due east. What is the direction of your friend's angular momentum around you at that instant

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.
