Doppler shift due to random motion of galaxies ,an aging of light as gravity weakens with time ,the difference in temperature and star formation in old and new galaxies
Nothing can be determined from the curve without seeing the curve.
There relationship can be the same in a way because both of those slopes can increase
The relative velocity of the athlete relative to the ground is 5.2 m/s
The given parameters;
constant velocity of the athlete, V = 5.2 m/s
let the velocity of the ground = Vg = 0
The relative velocity concept helps us to determine the velocity of a moving object relative to a stationary observer.
The athlete is the moving object in this question while the ground is stationary.
The relative velocity of the athlete relative to the ground is calculated as follows;

Thus, the relative velocity of the athlete relative to the ground is 5.2 m/s

Strong positive,
as high temperature increases, precipitation increases, so it’s positive.
And since the points are very close together, there is a strong correlation between the two variables, so it is strong.
