Air is made up mostly of O2, N2, and CO2. If the total pressure of air is 765 mmHg and P(n2) = 0.79 atm and P(co2) = 0.05 atm, then what is the partial pressure of O2?

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                                         : )

answer; how far out of place which the object finished relative to the starting location;
