Two planets have the same radius, but Planet A has twice the mass of Planet B. What happens to bulk density?
A
Planet A has eight times the density because radius is cubed.
B
Both planets have the same density because radius controls density alone.
C
Planet A has twice the density because the volume is the same.
D
Planet A has half the density because it is more massive.
