Answer:
C
Explanation:
Without thinking, the answer is C.
The problem is with D. Of course it is going to depend on the transparency. If the material is a rock, then the light won't go through, and n >>>1. I don't think you are intended to think that way, but I sure wish D wasn't there. I'd answer C, but be prepared to see it come out as D.
Force of Gravity depends on:

please, give the question properly.
Answer:
If the ship speed is doubled, then the power developed is 8 times the initial value.
Explanation:
ship power is roughly proportional to the cube of the speed, so
P ∝ v³
If the speed is doubled, then the power developed becomes
P ∝ (2)³ = 8 times
Therefore, if the ship speed is doubled, then the power developed is 8 times the initial value.
The answer is deflation...have a good day
