Answer:
they stay shifted the same amount to the red
Explanation:
Redshift is given by

Where,
= Wavelength observed
= Wavelength emitted
Also
Transverse redshift is given by

v = Velocity of object
c = Speed of light = 
So, if the velocity is constant the redshift remains the same
Answer:
100 Degrees is boiling point.
Explanation:
Answer:
Average speed equals distance / time
380 / 40 = 9.5 m/s.
Explanation:
The speed of car is 100.8km/h
