Question

If the velocity of light (3×10^8 m/s) be taken as one unit and the unit 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 length

1 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 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
