Every action force has an opposite and equal reaction force. determine which of these are action/reaction pairs. check all that apply. a girl leans against a wall and the wall pushes on the girl. a baseball hits a glove and the glove pushes on the ball. a boy pushes on a door and the door swings open. a soccer player kicks a ball and then another soccer player kicks the same ball. a cat rubs up against a tree and the tree pushes against the cat. a student pushes another student standing in a line, and that student falls into the next student.

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.
