Answer: Doppler effect
</h2>
Explanation:
A radar gun (also known as a Doppler radar) uses the Doppler effect when measuring "return echoes" after having sent a microwave signal (a type of electromagnetic radiation).
In this context the Doppler effect consists of the change in a wave perceived frequency when the emitter of the waves, and the observer move relative to each other.
In the case of radars, a microwave signal is sent to a target (the tennis or baseball in this case) and then is reflected after "hitting" the target, so that the radar system measures this difference between the sent signal and the reflected signal.

<span>To find the kind of transformation that describes this change from d(v) = 0.045v2 to d(v) = 0.039v2, find the relation between the two functions:
0.045/.039 = 45/39 = 15/13
The you have to multiply the first function times 13/15 to transform it to the second function.
When you multiply by a factor less than one you are compressiong the function vertically (if you multiply by a factor greater than 1 you are stretching vertically).
On the other hand, that the distance to stop the minimum braking distance will be smaller with the second function.
Then, the answer is that the transformation is a vertical compression by a factor of 13/15 and the braking distance will be less with optimum new tires than with tires having more wear.

Answer:
Mitosis
Explanation:
During mitosis, one cell divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
