I had this question before can you show me the answer choices
Answer:
209.66 m
Explanation:
Given:
Original length of the spaceship, L = 481 m
Speed of the spaceship, v = 2.70 × 10⁸ m/s
Now,
using the concept of length contraction, we have

where,
L' is the observed length
c is the speed of the light
Thus,
on substituting the respective values, we get

or
L' = 209.66 m
R = V/I = 9 / 0.3
R = <span>30 ohms.</span>
It's attached by earths gravity that keeps it the same force to stay anchored
