Answer:
C. 1.15
Step-by-step explanation:
We can calculate the gamma factor for an object moving at 0.5c, using the formula:
γ = 1/√(1 - v^2/c^2)
--------
where v is the velocity of the object and c is the speed of light.
Substituting v = 0.5c, we get:
γ = 1/√(1 - 0.5^2) = 1/√(1 - 0.25) = 1/√0.75 ≈ 1.155
--------
Therefore, the gamma factor for an object moving at 0.5c is approximately 1.155.
