Answer: D - Local winds blow over short distances, whereas global winds blow over long distance
Too easy:
100Ω/4 sec = 200Ω/t
t= 8 sec

Answer:
It takes 3 minutes.
Explanation:
The distance between the two subways is 3 miles.
The train travels at an average speed of 60mph (miles per hour).
We have to convert hours to minutes and we do that by cancelling out the hours and replacing it with minutes.
There are 60 minutes in an hour so we use that, 1 hour/60 minutes and multiply it to the existing speed we have.
The result is 1 mile per minute.
We then multiply the miles by 3 since that is how much we want and we get 3 minutes.
The problem is fairly simple if you use the formula.
Formula: Force = (mass) x (acceleration)
3 x 5 = 15 newtons
Note: 3 kg is the mass of the skateboard, and 5 m/s2 is the acceleration.
Answer: 15 newtons
