Two astronauts are 1.5m 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 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?

1311900 m far away from the earth

Explanation:

Given data

astronauts = 1.5 m

sound waves to travel = 343 m/s

to find out

How far away from the earth

solution

we know 2 astronauts are at distance 1.5 m from each other

and  sound travel  343 m/s

so time period = distance / sound speed

time period = 1.5 / 343 = 4.373 × sec

and time for sound reach at earth

speed of sound = 3 ×  m/s

so

time  = distnace /   3 ×

4.373 ×  = distnace /   3 ×

distance = 4.373 × × 3 ×

distance = 1311900 m

so 1311900 m far away from the earth

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
