Answer 1

Answer:

angstrom Å 10-10m

astronomical unit(average distance of sun from earth) AU 1.496 X 1011 m

light year(distance travelled by light in 1 year with velocity 3 X 108 m/s) ly 9.46 X 1011 m

parsec(distance at which average radius of earth's orbits subtends an angle of 1 arc second) pc 3.08 x 1016 m

Answer 2

Answer:

The SI unit for length l is a very small unit of measure astronomical distance their unit usually used is astronomy:

The astronomical unit AU-this is the average distance between the Earth and the Sun the unit is more used within the solar system.

1 AU=1.5×10¹¹m

Explanation:

This is because its definition is closely related to a method of measuring the distance between stars. apaar sake is the distance at which 1 AU subtend and angle of 1 arsec
