Asimple pendulum is displaced to the left of its equilibrium position and is released from rest. set the origin of the coordinate system at the equilibrium position of the pendulum, and let counterclockwise be the positive angular direction. assume air resistance is so small that it can be ignored. 1. beginning the instant the pendulum is released, select the graph that best matches the angular position vs. time graph for the pendulum. 2. beginning the instant the object is released; select the graph that best matches the velocity vs. time graph for the object. 3. beginning the instant the object is released; select the graph that best matches the acceleration vs. time graph for the object.

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.
