Question

The average distance of sun from earth is 1.496*10^11m express it in light years

Answer 1

Answer:

1.58×10^−5ly

Explanation:

Average distance of earth from the  sun,

r=1AU,=1.496×10^11m

As 1ly=9..46×10^15m and

1 par sec =3.1×10^16m

∴r =1.496×10^11ly/9.46×10^15

   =1.58×10^−5ly

Answer 2

Answer:

   1AU  = 1.58×10^−5ly

Explanation:

Average distance of earth from the

sun =1AU,=1.496×10^11m------- [1]

As 1 ly=9.46×10^15m------------[2]

Dividing 1 by 2, we get,

1 AU/ 1LY= 1.496×10^11m/ 9.46×10^15m

             1 AU  = 1.58×10^−5ly
