6
Q
RD=1
A
Fully submerged but neither sinking nor floating (eg: submarine)
7
Q
Density Formula
A
p=m/V
8
Q
Relative Density Formula
A
RD= Density of Object/Density of Water
9
Q
When finding density, if the mass and volume units are not apart of the same group, you must?
A
Convert the units (Ex: g->kg)

A
True
11
Q
When finding mass, the final unit must always be?
A
kg or g (Ex: N(Newton—>kg ms^-2)
