With what force is pushed out an oak block weighing 0.16 tons when it is fully immersed in water.

With what force is pushed out an oak block weighing 0.16 tons when it is fully immersed in water. Density of oak 800 kg / m3

Initial data: m (mass of an oak bar) = 0.16 t (160 kg); the oak block was completely submerged in water.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2; ρw (water density) = 1000 kg / m3; according to the condition ρd (density of dry oak) = 800 kg / m3.

The force with which the oak bar will be pushed out of the water is determined by the formula: Fa = ρw * g * V = ρw * g * m / ρд.

Calculation: Fa = 1000 * 10 * 160/800 = 2000 N (2 kN).

Answer: The oak block will be pushed out with a force of 2 kN.
