17. A racehorse is running down a track at a velocity of 12 m/s. The horse then accelerates at a rate of 2 m/s2 for 4 seconds. What is the final velocity of the horse
after 4 seconds? Round your answer to the nearest whole number.

What is the magnitude of the resultant vector round your answer to the nearest tenth

Where do magnetic lines of force enter earth?

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.
