If a star is moving away from you at a constant speed, how do the wavelengths of the absorption lines change as the star gets farther and farther?

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

representative si the final answer! : )

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
