This is probably a ridiculous question for many of you, but I want to make sure I have understood the significant figures rule. I am putting this in the physics section because it's from my physics book.
The Attempt at a Solution
a) Seconds in 1.00 year:
1 year x 365 x 24 x 60 x 60 = 31,536,000 seconds in a year = 3.15 x10^7 sec/y.
b) Nanoseconds in 1.00 year:
(Seconds in a year) x (nanoseconds in a second)= 31,536,000x1x10^-9 = 0.031536 = 3.15 x 10^-2 nanoseconds in a year.
c) Years in 1.00 seconds:
1.00seconds x (1 minute/60 seconds) x (1 hour / 60 minutes) x (1 day/ 24 hours) x (1 year/365 days) = 3.17x 10^-8 year in 1.00 seconds.
Would this be correct?
Thank you so much.
