You can have error both human error i.e eye balling a measurement to what looks close. and then you have inherent error the error that is already in the equipment i.e a 2 scales one can give a measurement of x when set to zero and if put it on a second scale you could get a measurement of y when set to zero because of calibration gravity etc things you cant control

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
The earth surface and when the sun and earth move. Plus the north and South hemisphere
