As shown in the figure below. April enters a race. She runs leftward 100 m to her horse, then she rides 500 m to her truck then she drives 1000 m in a total time of 120 s.

What is April's average velocity over the 120 s period?

What is April's average speed over the 120 s period?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
