Newton's Third Law states that for every action there is an opposite and equal reaction:
If the gravitational force of the Earth on the Moon is F then the gravitational force of the Moon on the Earth is also F
Explanation: Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater.

Answer:
The racetrack is 996.7 meters long
Explanation:
Convert 251km/h to km/s (kilometers per second)
3600 seconds in an hour, so:
251/3600 = 0.0697km/s
Convert km/s to m/s (meters per second)
1000 meters in a kilometer, so:
0.0697*1000 = 69.7m/s
Find length of racetrack:
69.7m/s*14.3s = 996.7m
If the racer travels 69.7 meters in one second and it takes 14.3 seconds to complete a lap, the racetrack is 996.7 meters long.
