Dude...you just want someone to do it for you..? Or..?
Answer:
The correct answer is - Both move with constant speed.
Explanation:
If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.
The relation between the variables x,t, and v is
x=v.t
If V is constant which is the speed we get a straight line x-t in the graph.
By the given information we can say that both objects A and B are traveling at a constant speed.
The Doppler Effect is also known as red shift. Red shift shows the distance of galaxies. The redder the shift then the further away the galaxy, however the bluer the galaxy then the closer it is. Red Shift shows that the universe is continuously expanding. <span />
