Answer:
rock will fall faster in air
Explanation:
We have given the density of water [tex]d=1000kg/m^3[/tex]
Density of air [tex]d=1kg/m^3[/tex]
Now according to Aristotle the falling of object inversely proportional to the density of the medium
[tex]rate\ of\ falling\ \propto\frac{1}{density}[/tex]
So the rock will fall faster in air as the density of air is low as compared to the density of water.
