If I ride my bike to school, and I have to go up hills and turn corners, would my speed from home to school be measured with instantaneous or average speed?

Give an example in which the electrical energy changes to light energy

What is the single most important equation in all of physics?

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.
