1. Two astronauts are 2.00 m apart in their spaceship. One speaks to the other. The conversation is transmitted to earth via electromagnetic waves. The time it takes for sound waves to travel at 354 m/s through the air between the astronauts equals the time it takes for the electromagnetic waves to travel to the earth. How far away from the earth is the spaceship?

Answer:

[tex]1.6949*10^6 m[/tex]

Explanation:

Our values are

[tex]d=2m[/tex]

[tex]v=354m/s[/tex]

We can find the time through

[tex]t=\frac{d}{v}[/tex]

[tex]t=\frac{2}{354}[/tex]

[tex]t=5.64*10^{-3}s[/tex]

The expression for the distance between the Earth and the spaceship is as follow:

[tex]d=ct[/tex]

Where c is Light speed, and t our previous time.

[tex]d= (3*10^8)(5.64*10^{-3})[/tex]

[tex]d= 1.6949*10^6m[/tex]

Therefore the distance between the Eath and the Spaceship is [tex]1.6949*10^6[/tex] m
