Question

Demonstrate that 1 pc equals 3.09 × 1013 km and that it also equals 3.26 light-years. Show your calculations.

Answer 1

3.266 light year

Step-by-step explanation:

that in 1 light year there is
`9.461* 10^(13)` km

hence
`9.461\It is given that [tex]1\ pc=3.09* 10^(13)` km

We knowtimes 10^{12}[/tex] km is equal to 1 light year

1 km equal to
`(1)/(9.461* 10^(12))` light year

So 1 pc that is equal to
`3.09* 10^(13)` km =
`(1)/(9.461* 10^(12))* 3.09* 10^(13)=3.266` light year
