Let the average diameter of the automobile tire is about 2 feet. Therefore its circumference is 
.
Now we have to convert an automobile tire is rated to last for 60,000 miles in to feet.
As 
.
So, 
Thus the number of revolutions,
Hence, order of magnitude of revolutions is 7.
Answer:
Approximately 11.43
Explanation:
Using the formula charge=current×time
then current=charge/time. That then will be C=96/8.4=11.4285714286 so approximately 11.43
In a Class One Lever, the Fulcrum is located between the Load and the Force.
Por the impulse, use the formula:
I = F * t
Now, we know:
4000 N = 4000 kg*m/s²
Replacing we have:
I = 4000 kg*m/s² * 0,200 s
Resolving:
I = 800 kg.m/s²
The impulse is <u>800 kg.m/s²</u>
