During an experiment a signal from a,spaceship reached the ground station in 5 minutes what was the distance of spaceship from the ground station if the signal travels at speed light of 3×10 raise power 8 m/sec |
| Answer» TIME taken by the SIGNAL to reach the ground station from the spaceship = 5 min = 5 × 60 = 300 s SPEED of the signal = 3 × 108 m/s ∴Distance travelled = Speed × Time taken = 3 × 108 × 300 = 9 × 1010 m Hence, the distance of the spaceship from the ground station is 9 × 1010 m.Explanation: | |
