Aball is thrown horizontally from a high cliff with a velocity of 5 m/s. ignoring the slowing of the ball due to air resistance (and assuming the ball is still falling), what will be the horizontal velocity of the ball 3 seconds later? a. 0 m/s b. 5 m/s c. 9.8 m/s d. 15 m/s

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.
