Idk

Answer 2

Since nobody wants to help, I will. The answers are-
Observer A and Observer B are moving at different speeds relative to each other.
Observer A is stationary and Observer B is moving.
When the object is moving away from the scientist.
Light wave frequencies increase as an object moves toward the observer.
I know it's EXTREMELY late- but it'll help everyone else who comes on this question!
You're welcome!
