A star lying 35 pc from the Sun has proper motion of 0.6 ′′/yr .

If the star's spectral lines are observed to be redshifted by 0.03 percent, calculate the magnitude of its three-dimensional velocity relative to the Sun.

Express your answer using two significant figures and include the appropriate units.

    Question :Suppose that you'd like to find out if adistant star is moving relative to the earth. The star is much toofar away to detect any change in its brightness as itmoves towardor away from the earth. Instead we can use the Doppler effect todetermine its relative speed. For this problem we are going to lookat the spectrallines from hydrogen, specifically the one with awavelength of 656.46 nm.(A)Suppose that you measure the light ofa star between 640 and 680 nm...
