When a car's velocity is positive and its acceleration is negative, what is happening to the car's motion? -the car slows down
-The car speeds up.
-The car travels at constant speed.
-The car remains at rest.

Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.

Explanation:

small = small current large mag large current

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
