At a baseball game, a pitcher throws the ball at 41.01 m/s to the catcher at home plate. If the mass of the baseball is 0.1299 kg, what impulse is required to provide the baseball with that much momentum?

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.
