Question

Assertion (A): The distance between two celestial bodies is measured in the unit of light year Reason (R): The distance travelled by the light in one year is one light year a. Both A and R are true but R is not the correct reason b. Both A and R are true and R is the correct reason c. A is true but R is false d. A is false but R is true

Answer 1

Ans-

false d. A is false but R is true

The distance among two celestial bodies is measured in the unit of light year is false because Distances between galaxies and suns are measured by light years with suns and distances to extra solar planets.

The larger astronomical unit i.e. A.U. is 149 598 000 kilometers.

For that mean distance between earth and sun or inside solar system measurement (distance between two planets in our solar system are measure in miles and km) can be used.
