Agas is placed inside a very cold box. the gas molecules transfer heat to the walls of the box. which best describes what happens to the gas as it cools down? the gas molecules slow down, and some change phase to liquid. the gas molecules speed up due to collisions with the walls. the gas molecules vibrate around fixed positions. the gas molecules gain energy from the cold walls of the box.

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.

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

Which of the following examples illustrates static friction? a box sits stationary on a ramp. a ball rolling on the lawn eventually comes to rest. a car rounds a curve on a road. a fish swims upstream.
