Question

laser signal sent from the Earth takes a time of 1.28 seconds to reach the moon if the speed of the laser signal be 3 into 10 power 8 metre per second calculate the distance of the Moon from the Earth ​

Answer 1

Answer:

Explanation:

=> Here, laser signal sent from the Earth takes a time of 1.28 seconds to reach the moon

Time, T = 1.28 seconds

Speed of the laser signal, S = 3 * 10⁸ m/s

The distance of the Moon from the Earth ​= ?

=> Speed = Distance/ time

Distance = speed * time

=  3 * 10⁸ * 1.28

= 3.84 * 10⁸ m

Thus, The distance of the Moon from the Earth is 3.84 * 10⁸ m.

Answer 2

Answer:

I think the answer is 3.84*10^8m.
