Question

Given below are two statements :

Statements $I$ : Astronomical unit $(Au)$. Parsec $(Pc)$ and Light year $(ly)$ are units for measuring astronomical distances.

Statements $II:$ $Au < Parsec ( Pc ) < ly$

In the light of the above statements. choose the most appropriate answer from the options given below:

✓

Answer

$1 AU =1.496 \times 10^{11}\,m$

$1 \text { par sec }=3.08 \times 10^{16}\,m$

$1 \text { light year }=9.46 \times 10^{15}\,m$

So, $Au < ly < Per\,sec$
