Moira is drawing the electric field lines around a pair of charges. one charge is positive, and the other charge is negative. how should she draw the field lines? a) away from each charge and meeting in the middle b) away from each charge and curving away from one another c) away from the positive charge and toward the negative charge d) away from the negative charge and toward the positive charge

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 force applied to an object remains constant, is more power needed for the object to move faster ? explain

The ph is the a.independent variable b.the dependent variable c.control group
