The distance between two asteroids is 1600 km.How much time does it take for a light signal to go from one asteroid to the other? (c = 3.0 × 10⁸ m/s)

Question

To find the time taken by the light signal to travel from one asteroid to the other, we can use the formula:

time = distance/speed

Here, the distance between the asteroids is given as 1600 km, which is equal to 1.6 x 10^6 m (1 km = 10^3 m). The speed of light is given as 3.0 x 10^8 m/s.

Therefore, the time taken by the light signal to travel from one asteroid to the other is:

time = distance/speed
time = 1.6 x 10^6 m / 3.0 x 10^8 m/s
time = 5.3 x 10^-3 s
time = 5.3 ms

Therefore, the best choice is C) 5.3 ms.

The Distance Between Two Asteroids Is 1600 Km
