The galaxy NGC 4414 is moving away from us at 7.16x10^5 m/s. By how much will the
frequency of the 6.91x10^14 Hz hydrogen line
be shifted in the galaxy's spectrum?
(Answer is x10^12 Hz. Just fill in the
number in the blank, not the power.)

Could someone . i have tried to solve myself but my calculation is off

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
