The gas pressure inside a piston-cylinder device is initially balanced by atmospheric pressure. The initial pressure is 100 kPa and volume of the gas in the cylinder is 32 cm3. A spring attached to the outside of the piston exerts no force on the piston. The area of the piston is 0.0004 m2. Heat transfer to the gas causes the piston to move upwards by a distance of 2 cm. The spring constant is 10 N/cm. (a) Determine the final absolute pressure (kPa) of the gas. (b) Calculate the final volume (cm3 ) of the gas. (c) Show the expansion process on a P-V diag

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
