Gravity!! It also keeps the planets in orbit!
Answer: The average speed is 5.71 m/s
Explanation:
The average speed in this run will be the quotient between the total distance that the runner traveled, and the total time it took.
Distance = 400m + 400m + 800m = 1600m
Time = 80s + 70s + 130s = 280s
Then the average speed is:
S = 1600m/280s = 5.71 m/s
The fronts that produce the most storms are those that have the highest difference in temperature, and the highest levels of water vapor. Warm, moist air is unstable, and contact with colder air can trigger extreme weather events. The key factor is convergence of winds produced in the area along the front<span>.</span>
