Two pounds of carbon dioxide (CO2) as an ideal gas executes a Carnot power cycle while operating between thermal reservoirs at 540 and 100 oF. The pressures at the initial and final states of the isothermal expansion are 400 and 200 lbf/in2, respectively. The specific heat ratio is k

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

we need to know the time interval during which the force acts. impulse of force = momentum change
