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

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

c.the charges if the proton and electron and gravity
