Question

Heya!!!!❤❤❤❤
✨Define one parsec. Express it in terms of metres.
Thanks for help✌

Answer 1

distance at which one astronomical unit's substends an angle of one arc second which corresponds to 648000π astronomical units.
one parsec = 3.26 light years
= 3.09 × 10 ^ 13 km
= 3.09 × 10^16 m

Answer 2

hey mate

here is ur answer

one parsec is the distance from where the semi major axis of orbit of earth (1A.U) subtends an angle of one second

ie parsec *1 =I A.U
or
1 parsec = 1.496*10raise to the power 11 m /(1/3600)*(22/7/180)=3.08 *10 raise to the power 16

=3.08 *10 raise to the power 16 /9.4*10 raise to the power 15. ly = 3.26 ly

hope it will helps u and pls mark it as the brainliest
