Explanation:
Below is an attachment containing the solution.
The answer is Hertz (Hz) named in honor of the German scientist Heinrich Hertz, who first conclusively proved the existence of electromagnetic waves.
Average speed = (distance covered) / (time to cover the distance)
Average speed = (4 meters) / (5 seconds)
Average speed = (4/5) (meters/seconds)
Average speed = 0.8 m/s
Answer:
option B) is correct
Explanation:
perception distance is the distance traveled by the vehicle when the driver perceive the hazard situation.
reaction distance is the distance traveled by the vehicle after seeing the hazard situation and reacting to it.
Braking Distance is the distance traveled by the vehicle after applying the brake.
so, the sum of Perception Distance + Reaction Distance + Braking Distance is called the total stopping distance
hence option B) is correct .
