Awatermelon is dropped from the top of a 80m tall building. we want to find the velocity of the watermelon after it falls for 1.35s. we can ignore air resistance. kinematics formula would be most to solve for the target unknown? answer choices in picture.

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.
