An object weighs 100 N on the surface of the earth. Find its weight if it was 6.38 x 10' m above the surface?

where are the vectors ?

double the distance = divide strength by 4

magnified images possible images can be real = projected onto a screen

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
