Achair is at rest on the floor. the chair absorbs thermal energy from the floor, and begins moving spontaneously with kinetic energy equal to the thermal energy absorbed. this process violates

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 junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
