Astudent on her way to school walks eastward in a straight line 20.0 meters towards the bus stop, but realizes she dropped her physics notebook along the way and turns around to retrace her steps. she has traveled back 18.0 meters before finding it and then runs the remaining 45.0 meters due east to the bus stop. what is her total displacement? what is her total distance traveled?

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.
