1) As velocity of the galaxy goes up, the distance (width) 2) What type of relationship is this, direct or indirect?

i'm assuming that the correct answer is indeed the first one/ "a"..

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

i think its 5049.

i hope this !
