ro oil = 900 kg / cm cubed – this cannot be, ro oil = 900 kg / cubic meter
Let’s translate all the values from given to the SI system:
V = 10 cm³ = 1 * 10-5 m³
According to Archimedes’ law:
A buoyant force equal to the weight of the displaced fluid acts on a body immersed in a liquid, and is called the Archimedes force:
Fa = ρ * g * V, where ρ is the density of the liquid, g is the acceleration of gravity of a body raised above the Earth g = 9.8 m / s², V is the volume of the body.
Substitute numerical values into the Archimedes formula:
Fa = ρ * g * V = 900 * 9.8 * 1 * 10-5 = 0.088 N
Answer: 0.088 N
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
