1. First is Ultraviolet
2. Next is Infrared
3. Then the radio
4. Lastly the Visible lights.
These are the answers to the problem.
Answer:
The average angular acceleration is 
Explanation:
From the question we are told that
From the question we are told that
The length of the bat is
\
The initial linear velocity is 
The time is 
The velocity at t is 
Generally average angular acceleration is mathematically represented as

Where
is the finial angular velocity which is mathematically evaluated as



and
is the initial angular velocity which is zero since initial linear velocity is zero
So

For a lens, the following sign convention is generally used:
- f (the focal length) is positive for a converging lens and negative for a diverging lens
-

(the distance of the object from the lens) is positive if the object is in front of the lens and negative if it is behind the lens
-

(distance of the image from the lens) is positive if the image is behind the lens (real image) and negative if the image is in front of the lens (virtual image)
Therefore, the correct option is
<span>A. +di
</span>which mens that the image is real and located behind the lens.
