If a crime scene investigator takes photos of a crime scene, it is not necessary to take notes? true or false

This statement is False.

It is false beacuse if you only take a picture you never know. But if you also take notes( or just notes ), you could find something or you can find out that there was someone behind it all

Explanation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
