Javon Lee · Answer 1

Answer: The correct answer is option C.

Explanation:

From the following question, the third option is right, because when the shining light create a horizontal beam over the spacecraft, the observer who is on the earth would see that light in the same way at the time spacecraft is at rest and when observer in the spacecraft at the time spacecraft is at rest.

So this is the correct answer.

Ingrid Hardy · Answer 2

C. an observer on Earth while the spacecraft is at rest and an observer inside the spacecraft while the spacecraft is at rest

Explanation:

The third option is the most accurate from the all the other option, since if the bright light produces a continuous horizontal beam over the spacecraft, the spectator on planet earth would see the light in the same pattern when the spacecraft is at stationary and when the observer in the spacecraft is at a distance r.
