During the process of differentiation,
1. the faster planets move farther out from
the Sun.
2. satellites separate from parent planets
and go into their own orbits.
3. the atmosphere of a planet changes from
oxidized to reduced.
4. the surface of a planet changes to resemble
Bayonne, New Jersey.
5. heavier materials sink to the centers of
molten planets.

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.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =
