The avarage distance from the earth to the sun is `1.49xx10^(11)` m. Find out the value of 1 par second in meter.

Explanation

If r is asverage distance of earth from the sun, by definition,
`(r )/(1 par sec) = 1'' of arc = (1)/(60xx60)xx(pi)/(180)rad`
`:. 1 par sec = (rxx60xx60xx180)/(pi)m`
As `r = 1.49xx10^(11)m, therefore,`
`1 par sec = (1.49xx10^(11)xx60xx60xx180)/(3.14)`
`1 par sec= 3.08xx10^(16)m`
