Question

If the velocity of light be taken as one unit and the of time as one year of 365 days, find the unit of length

Answer 1

As velocity of light is taken as 1 unit and unit of time as 1 year (365 days), therefore
1 unit velocity of light=1 unit length1 unit time⇒1 unit length=1 unit velocity of light×1 unit time⇒1 unit length=3×108×365×24×60×60=94608000×108=9.4608×1015 m

Answer 2

Answer:

Explanation:

1 unit velocity of light=1 unit length1 unit time

⇒1 unit length=1 unit velocity of light×1 unit time

⇒1 unit length=3×108×365×24×60×60

=94608000×108

=9.4608×10^15
