Answer:

Explanation:
From the question we are told that
Speed of star 
Distance of spectral line 
Generally the equation for wavelength with respect to spectral lines is mathematically given by

where



therefore


Generally the equation for new wavelength is mathematically given as



Therefore

Answer:
A) The net force
Explanation:
If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement.
Einstein's equations showed that matter could be converted into energy; and vice-versa

If the acceleration is centripetal then the formula is a=v^2/r
Plug in 58.8=v^2/.400 solve for v
V=12.12 m/s
