Answer:

D=Vi*t+1/2a*t^2

D=(8)(40)+(.5)(9.8)(40^2)

D=(8)(40)+(.5)(9.8)(1600)

D=(320)+(.5)(9.8)(1600)

D=(320)+(4.9)(1600)

D=(320)+7840

D=8180meters.

Answer: Because of different redshift of cloud.

Explanation:

We are seeing absorption lines from clouds of gas that lie between us and the quasar, and therefore each cloud has a different redshift.

A quasar's spectrum is hugely redshifted. And most astronomers think this large redshift tells us about the distance to the quasar.
