Hello!

Your answer would be:

[tex] P_{A} [/tex] = [tex] P_{B} [/tex]
⇒[tex] P_{0} [/tex] + [tex] p_{0}[/tex][tex] ^{h} [/tex] = [tex] P_{0} [/tex] + [tex] p_{w} h_{w} [/tex] ; where [tex] h_{w} [/tex] = h - 2cm
⇒[tex] P_{0} [/tex] = [tex] \frac{ P_{w} h_{w} }{h} [/tex] = [tex] \frac{1 * (0.1 - 0.02)}{0.1} [/tex] = 0.8 g/[tex] cm^{3} [/tex] = 800 kg/[tex] m^{3} [/tex]


I hoped this helped. c;

The density of water is 1.00 g/cm3 whereas the density of the oil is 700 to 950 g/cm3.

We know that density depends on the mass. Higher the mass higher will be the density and lower the mass lower will be the density. Some oils are less denser so they have less density while on the other hand, other oils have more denser so they have more density.

The value of density depends on the composition of oil molecules. Water is more denser than oil so when we mix them the oil make its layer on the upper surface of so we can conclude that the density of oil ranges from 700 to 950 g/cm3.
