The formula by which the pressure of a liquid or gas is calculated is …

First, let’s write down what each formula is for:

a) P = g * m – to determine the weight, where P is the body weight, g is the gravitational acceleration equal to g = 9.8 H / kg, m is the body weight.

b) p = g * p * h – to determine the pressure in a liquid or gas.

p is the pressure;

g – acceleration due to gravity, equal to g = 9.8 H / kg;

m is the mass;

p is the density of the substance.

c) m = p * V – to determine the mass.

V is the volume of the substance;

p is the density;

m is the mass.

d) p = F / S – to determine the pressure in solids, where p is the pressure, F is the force, S is the area.

The formula by which the pressure of a liquid or gas is calculated is p = g * p * h.

Answer: p = g * p * h.
