For each star, determine how its light would be shifted. Not all choices may be used, and some may be used more than once. A blue giant moving away from Earth at 39.9 km/s A yellow dwarf moving transversely at 16.3 km/s A red giant moving towards Earth at 22.7 km/s A blue dwarf moving away from Earth at 37.9 km/s A blue giant moving transversely at 30.1 km/s

Explanation:

To solve this problem we have to consider the general red shift equation

z=red shift

v=speed of the object

c=speed of light

θ=angle between earth and relative motion of the object

- For objects moving away θ=0 and for relative transverse motion θ=90°. Hence we have for both class of motion

a)

for the blue giant

b)

for the yellow dwarf

c)

and in the same way for the red giant (but with an angle of 180°)

z = -7.56*10^{-5}

e)

and for the blue dwarf

z = 7.98*10^{-9}

I hope this is useful for you

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
