^Light year (ly)
It is the distance travelled by light in vacuum (with a speed of 3 x 108 m/s) in one year
(i.e., 365 x 24 x 60 x 60 s).
1 ly = 3 x 108 x (365 x 24 x 60 x 60) » 9.5 x 1015 m
^A long horizontal fixed wire carries a current of 100 A. Directly above and parallel to it is another wire carrying a current of 20 A and weighing 0.04 N/m.
