Consider a vehicle trying to pull another vehicle with a rope (PI: Vehicle in Tow). One of the vehicles is stuck in mud. What are the components (parts) of the system that influence its motion?
(two vehicles, the rope connecting them, the ground/mud, and the planet Earth [the source of gravity])

Avalue that describes how heavy an object is and is related to the force of gravity is

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.
