Question

Пластиковый пакет с водой объёмом 2 л полностью погрузили в воду.Определите выталкивающую силу,действующую на пакет.Плотность воды 1000 кг/м в кубе

Answer 1

Fa=p*g*V=1000*10*2/1000=20 H

Answer 2

Calculation of the Buoyant Force

To determine the buoyant force acting on the plastic bag filled with water, we need to calculate the volume of the bag and then use the formula for buoyant force.

The volume of the bag can be calculated using the formula:

Volume = mass / density

Since the mass of the water in the bag is equal to its volume, we can substitute the mass with the volume in the formula.

Given that the volume of the bag is 2 liters (or 0.002 cubic meters) and the density of water is 1000 kg/m^3, we can calculate the buoyant force.

Calculation:

Volume of the bag = 0.002 m^3

Density of water = 1000 kg/m^3

Using the formula for buoyant force:

Buoyant force = Volume of the bag * Density of water * Acceleration due to gravity

Substituting the values:

Buoyant force = 0.002 m^3 * 1000 kg/m^3 * 9.8 m/s^2

Calculating the result:

Buoyant force = 19.6 N

Therefore, the buoyant force acting on the plastic bag filled with 2 liters of water is 19.6 Newtons.
