Your eye can see down to +6 mags. for a typical star of absolute mag of +4, what is the farthest you can see into space?

-6+4=-2
so the farthest you can see is -2

hope it help:)

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
