Question

1. 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 × 10⁸ m s^-1.​

Answer 1

The signal travels at the speed of light, that is, 3×108ms−1. Hint – Here we will proceed by using the formula for speed to find out the distance of the spaceship from the ground station. So the distance of the spaceship from the ground is 9×1010 meters.

Answer 2

Explanation:

$\blue{\mathfrak{\underline{\large{Given}}}:} \\ time \: taken \: by \: the \: signal \: from \: spaceship \: to \: reach \: ground \\ =5min \\ =5 \times 60 \\ = 300s \\ speed \: of \: light \: =3 \times {10}^{8} m {s}^{-1} \\ \blue{\mathfrak{\underline{\large{To \: find}}}:} \\ distance \: travelled \: by \: signal \: from \: spaceship \: to \: ground \\ \blue{\mathfrak{\underline{\large{Finding}}}:} \\ speed= \frac{distance}{time} \\ distance=speed \times time \\ = 3 \times {10}^{8} \times 300 \\ = 9 \times {10}^{10} m \\ \blue{\mathfrak{\large{distance \: travelled \: by \: signal \: from \: spaceship \: to \: ground}}} \\ = 9 \times {10}^{10} m \\ \red{\mathfrak{⟨\underline{\large{Hope \: It \: Helps \: You}}}⟩} \\ \blue{\mathfrak{⟨\underline{\large{Mark \: Me \: Brainliest}}}⟩}$
