Given below are two statements: Statement I: Astronomical unit (Au), Parsec (Pc) and Light year (ly) are units for measuring astronomical distances. Statement II: Au

Question

Given below are two statements: Statement I: Astronomical unit (Au), Parsec (Pc) and Light year (ly) are units for measuring astronomical distances. Statement II: Au<Parsec (Pc)<ly. In the light of the above statements, choose the most appropriate answer from the options given below

Accepted Answer

(2) Statement I is correct but Statement II is incorrect.. Statement I: the astronomical unit, parsec and light year are all used for astronomical distances. Correct. Statement II: 1 Au=1.496×10¹¹ m, 1 ly=9.46×10¹⁵ m, 1 pc=3.086×10¹⁶ m. The true order is Au<ly<pc, with one parsec about 3.26 light years. Statement II reverses the last two, so it is incorrect.
