You drove 20 more mph than what you did before. The more force is 20 because you drove 20 more mph.
Answer:
in order to find the average velocity use change in Displacement / change in time?
Explanation:
Answer:
we understand it by electromagnetic spectrum. and we velength is the distance between identical location on adjecent waves ( see figure below)
Rain that tends to fall in bands on earth is usually caused by : Warm, moist air rising and cooling
First, the water on earth evaporate due to sun's heat and formed cloud. Later on, this water condensed and fall again on the earth. Completing the water cycle
hope this helps
Work can be obtained from the following expression
W = F*d
Where F is the force (In this case the force it takes to lift Sarah, which is mass*gravity)
And d is the distance traveled.
W = 60kg*9.8m/s^2 * 4m = 2352 Joules
