On the last day of school, Ms. Ahmad starts from rest at the building doors and accelerates in a straight line at 1.8 m/s2 . a. How fast is she traveling at the end of 3 seconds?
b. How far did she travel while she accelerated those 3 seconds?

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.
