Answer:
The first vehicles fitted with an alternator was vehicles during WWll.
Chrysler Corporation fitted an alternator on the Valiant 1960 as standard equipment
Explanation:
To calculate for the frictional force, we calculate first for the normal force (forcer perpendicular to the surface)
Fn = (2,493 kg) (9.8 m/s²) = 24243.51 N
Then, we multiply this value with the frictional constant which is not given in this problem. If the frictional coefficient is equal to x then, the frictional force is equal to 24243.51x.
Answer:
Her average speed is 0.25 miles / hour.
Explanation:
I did 0.5 divided by 2 = 0.25 miles / hour.

The velocity will remain unchanged (Newton’s 1st Law) unless a force acts on it. If no friction force, then the velocity remains constant.
Answer:
Option A
Explanation:
In this experiment, when balloon is rubbed on the chair electrons are transferred from the hair to the surface of the balloon thereby making balloon negatively charged and hair positively charged. When two negatively charged balloon are brought close to each other, they repel while when balloon is brought closer to the hair, they attract each other
Hence, option A is correct
