1. i drop a penny from the top of the tower at the front of fort collins high school and it takes 1.85 seconds to hit the ground. calculate the velocity in m/s after 1.10 seconds of freefall and calculate the velocity at impact in mi/hr.

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.
