Given data,
Distance = 0.48 m
Speed = 343 m/s
We know that,
Time = Distance / speed
= 0.48 m / 343 m/s
= 1.39 x 10-3 s
The distace between earth and spaceship is
d = c t
= ( 3.0 x 108 m/s) (1.39 x 10-3 s)
= 4.17 x 105 m
Option c is correct

Two astronauts are 2.0 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 348 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? m
Two astronauts are 1.90 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 340 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?
Two astronauts are, 6.207 m apart in their spaceship, speaking to each other. The conversation is transmitted to Earth via electromagnetic waves traveling at the speed of light. The time it takes for the sounds waves to travel at 343 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?
