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 red dwarf moving away from Earth at 39.1 km/s

A yellow dwarf moving transversely at 15.1 km/s

A red giant moving towards Earth at 23.3 km/s

A blue dwarf moving away from Earth at 25.9 km/s

A red dwarf moving transversely at 14.1 km/s

Explanation:

To calculate the red shift you use the following formula:

\tetha: angle between the observer and the motion of the body

v: speed of the body

c: speed of light

for motion with angle 90° (transversal motion):

- A red dwarf moving away from Earth at 39.1 km/s :

- A yellow dwarf moving transversely at 15.1 km/s (angle = 90°):

- A red giant moving towards Earth at 23.3 km/s (angle = 0°):

- A blue dwarf moving away from Earth at 25.9 km/s

- A red dwarf moving transversely at 14.1 km/s

the answer would be 32*f
