A ball was thrown with an initial velocity of 20 m/s at an angle. It remained in the air for 5 seconds. What quantities remain constant while the ball is in the air?

An uplifted block of rock between two normal faults

With i really need the correct answer!

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.
