The best theory for how our Moon formed is... that a rapidly rotating Earth ejected material that formed the Moon.

that they formed together via accretion in the protoplanetary disk.

that the Earth gravitationally captured the already formed Moon.

that a huge planetesimal collided with the Earth and the resulting debris formed the Moon.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

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.
