Question

Какая физическая величина равна отношению массы тела к его объему ?

Answer 1

Это плотность ..........................

Answer 2

Physical Quantity Equal to the Ratio of Mass to Volume

The physical quantity equal to the ratio of mass of a body to its volume is density.

Density is defined as the mass per unit volume of a substance. It is calculated using the formula:

Density (ρ) = Mass (m) / Volume (V)

Where: - ρ = Density - m = Mass - V = Volume

The SI unit of density is kilograms per cubic meter (kg/m³).
