An air pistol contains compressed air in a small cylinder. assume that the volume is 1 cm3, pressure is 1mpa, and the temperature is 27°c when armed. a pellet, m = 2g, acts as a piston, initially held by a pin (trigger); when released, the air expands in an isothermal process (t = constant). if the air pressure is 0.1 mpa in the cylinder as the bullet leaves the gun, find a. the final volume and the mass of air. b. the work done by the air and work done on the atmosphere (the bullet pushes the atmospheric

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
