A bullet with a mass of 0.01kg is fired from a firearm with a barrel that is 0.34 m long. If the Force exerted by the expanding gas is 5,180 N,
what is the kinetic energy of the bullet leaving the firearm?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
