Aspaceship carrying a light clock moves at a speed of 0.96c relative to an observer on earth. relative to a frame of reference that is fixed with respect to the earth, how long does it take the clock to advance 1 s?

Explanation:

Given:

Speed of spaceship, v = 0.96c

using the time dilation formula, we have

where,

t₀ = time in observer's frame

t = time in observed frame

c = speed of light

substituting the values in the above equation, we get

or

or

now, it is given that t = 1s  advance

thus,

or

the answer is b i think
