Acar is moving in uniform circular motion. if the car's speed were to double to keep the car moving with the same radius, the acceleration would

increase by a factor of 2
increase by a factor of 4
decrease by a factor of 2
decrease by a factor of 4

Increase by a factor of 4.

Explanation:

The acceleration of a car moving with speed v in a circle of radius R is given by:

Now if we double the speed in the equation above, it becomes . Thus:

Therefore the acceleration is increased by a factor of 4.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

heats surface water up
