What is the round-trip travel time of light from Earth to Neptune (at a distance of 30 AU)? How far would a spacecraft orbiting the planet at a speed of 0.5 km/s travel during that time?
How far would a spacecraft orbiting the planet at a speed of 0.5 km/skm/s travel during that time?
Answer
1
Hour
minutes
Answer 2
Km
m
m
m
We know ,
Distance (s) = Speed (v) * Time (t)
When the particle is moving with a uniform speed.
Here , light travels in vacuum which is uniform speed i.e
m/s
Hence
Therefore the round trip travel time for a light from Earth to
Neptune is
s
minutes
Hour
minutes
Now , the speed of a space craft(v)=
Km/s
Therefore the
space craft orbiting the planet at adistance of 15000
Km.
