Text Solution

Verified by Experts

The correct Answer is:
B, D

We know that 1 light year `= 9.46 xx 10^(11) m`
= distance that light travels in 1 year with speed
`3xx10^8 m//s`
1 parsec = `3.08 xx 10^(6)` m
= Distance which average radius of earth.s orbit subtends an angle of 1 parasecond Here, Second and year represent time.
