relation between 1AU and 1 parsec
Answers
Answer:
Hello Dear.
Here is the answer---
←→→→→→→→→→
Astronomic unit(A.U.) : One A.U. is equal to the Mean distance between the Earth and the Sun.
1 A.U. = 1.496 × 10¹¹ m.
⇒ 1 m = (10⁻¹¹/1.496) A.U. --------------------eq(i)
Parsec : One Parsec is the distance from the semi major axis of the orbits of the earth subtends an angle of one second of arc at the centre of the sun.
One Parsec is 3.26 times the light year.
1 Parsec = 3.26 Light Year.
= 3.26 × 9.46 × 10¹⁵ m.
= 30.8396 × 10¹⁵ m.
⇒ 1 m = (10⁻¹⁵/30.8396) -----------------------eq(ii)
From eq(i) and eq(ii),
(10⁻¹¹/1.496) A.U. = (10⁻¹⁵/30.8396) Parsec.
⇒ 1 Parsec = (30.8396/1.496) × 10⁴ A.U.
⇒ 1 Parsec = 20.6147 × 10⁴ A.U.
⇒ 1 Parsec ≈ 2.06 × 10⁴ A.U.
Thus, the Relation between the Parsec and the A.U.(Astronomical Unit) is Proved above.

Answer:
Hey mates
Here is your answer
Astronomic unit(A.U.) : One A.U. is equal to the Mean distance between the Earth and the Sun.
1 A.U. = 1.496 × 10¹¹ m.
⇒ 1 m = (10⁻¹¹/1.496) A.U. --------------------eq(i)
Parsec : One Parsec is the distance from the semi major axis of the orbits of the earth subtends an angle of one second of arc at the centre of the sun.
One Parsec is 3.26 times the light year.
1 Parsec = 3.26 Light Year.
= 3.26 × 9.46 × 10¹⁵ m.
= 30.8396 × 10¹⁵ m.
⇒ 1 m = (10⁻¹⁵/30.8396) -----------------------eq(ii)
From eq(i) and eq(ii),
(10⁻¹¹/1.496) A.U. = (10⁻¹⁵/30.8396) Parsec.
⇒ 1 Parsec = (30.8396/1.496) × 10⁴ A.U.
⇒ 1 Parsec = 20.6147 × 10⁴ A.U.
⇒ 1 Parsec ≈ 2.06 × 10⁴ A.U.
Thus, the Relation between the Parsec and the A.U.(Astronomical Unit) is Proved above.
