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
Convert to SI and write in scientific notation:
1) 1.282 light-seconds to m
2)1 acre to m2
How does F becomes such form, why power of 3, and why times (xi-xj)?
