Answer:
car B will be 30 Km ahead of car A.
Explanation:
We'll begin by calculating the distance travelled by each car. This is illustrated below:
For car A:
Speed = 40 km/h
Time = 3 hours
Distance =?
Speed = distance / time
40 = distance / 3
Cross multiply
Distance = 40 × 3
Distance = 120 Km
For car B:
Speed = 50 km/h
Time = 3 hours
Distance =?
Speed = distance / time
50 = distance / 3
Cross multiply
Distance = 50 × 3
Distance = 150 Km
Finally, we shall determine the distance between car B an car A. This can be obtained as follow:
Distance travelled by car B (D₆) = 150 Km
Distance travelled by car A (Dₐ) = 120 Km
Distance apart =?
Distance apart = D₆ – Dₐ
Distance apart = 150 – 120
Distance apart = 30 Km
Therefore, car B will be 30 Km ahead of car A.
Newton's Third Law States that Every Action Has an Equal and Opposite Reaction. To stop or slow down an object, a force must be applied in the direction opposite to that of the object's motion. Exerting a force results in an equal force in the opposite direction (like the recoil a person feels when firing a gun)
never seen one although i guess the elegant answer is D) none of the mentioned posibilities
Thinking back to my classes from last year, I'm pretty sure it's gas as the cells move faster and are spread apart more than in a solid form.
