I'm kind of confused about the question
But according to the Kardashev scale<span> there are 3 civilizations that life other civilizations want to get to
1. The civilization is confined to its own planet like humans and Earth (we suck)
2. A civilization harnesses the full power of there star through maybe a dyson sphere or more realistically a dyson swarm
3. And 3 is when a civilization harnesses the full power of there galaxy and many stars in it. </span>
Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
Answer:
Δt ≈ 2.9137 ≈ 3 seconds per kilometer
Explanation:
The speed of light is approximately 300000 km /s, while the speed fo the sound in the air is 0.3432 km/s.
The light takes therefore this time to travel one kilometer
On the other hand the sound takes this time to travel one kilometer
t = 2.9137 s
Then the delay time is 2.9137 -
Δt ≈ 2.9137 ≈ 3 s
Answer:2√(2)km Southeast
Explanation:
Displacement=√(2)+√(2)=2√(2)km Southeast
