A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s.
How many meters are there in 1.70 ly?
Express your answer using three significant figures. Express in scientific notation!
1.70 ly = _________________m
How many AU are there in 1.70 ly light-year?
Express your answer using three significant figures. Express in scientific notation!
1.70 ly = _________________AU
If I drove 55 kilometers per hour, how long would the trip take one way? It takes 452 miles for the round trip and 3hrs and 4 minutes for one way.
The age of the universe is thought to be about 14 billion years. Assuming two significant figures, write this in powers of 10 in:
(a) years,
(b) seconds.
