Question

During an experiment, a signal from a spaceship reached the ground station in five seconds. What was the distance of the spaceship from the ground station? The signal travels at the speed of light that is 3 ×108ms-1

Answer 1

Answer:

Explanation:

Time=5sec , speed=3x108m/s1 distance=speed x time so,5x324=1620m. So d=1620m

Answer 2

Answer:

9 × 10`10 m.

Explanation:

Speed of the light = 3 × 10`8 m/s  (Given)

Time taken by the spaceship = 5 seconds (Given)

Since, 1 minute is equal to 60 seconds

Therefore, 5 minutes will be equal to = 5 × 60 s = 300 s

According to distance formula -

Distance = Speed × Time

= 300 × 3 × 10`8

= 9 × 10`10

The distance of the spaceship from the ground is 9 × 10`10 m.
