Question

look like when it is in unifo motion? 5. During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, 3 x 108 ms-​

Answer 1

Answer:

→ 3 × 10⁹ metres

Explanation:

Given,

An experiment, where a signal with a speed of light takes 5 min to reach the ground station.

We need to find the distance.

Speed of light is :-

= 3 × 10⁸m/s

Time taken to reach the ground station :-

= 5min

Converting into seconds :-

∵ 1 min = 60 sec

∴ 5 min = 5*60 = 300 sec.

Here,

Distance covered by the signal = Distance between the spaceship and the ground station.

Formula :-

→ D = s * t

Where,

• s(speed) = 3 × 10⁸ m/s
• t(time) = 300 sec.

So,

→ D = 3 × 10⁸ × 300

→ D = 3 × 10⁸ × 3 × 100

→ D = 9 × 10⁸ × 100

→ D = 9 × 10⁹m.

∴ Distance between the spaceship and the ground station is 9 × 10⁹metres
