Question

У бочку, наповнену водою, вставили трубку висотою 1 м i налили в неї води. Яка сила діє внаслідок цього на бочку, якщо її площа 2,2 м² ?​ ДАЮ 70 БАЛЛОВ

Answer 1

Ответ:

22 кН

Объяснение:

P = pgh = 1000*10*1 = 10 000па

P = F/S

F = PS = 10 000*2.2 = 22 000 Н = 22 кН

Answer 2

Calculation of Pressure Exerted on the Barrel

To calculate the pressure exerted on the barrel, we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Given that the height of the water column is 1 m and the area of the barrel is 2.2 m², we can calculate the force exerted on the barrel by the water.

Calculation

The force exerted by the water on the barrel can be calculated using the formula:

Force (F) = Pressure (P) × Area (A)

Substituting the given values: Force (F) = Pressure (P) × 2.2 m²

Now, we need to calculate the pressure exerted by the water on the barrel.

Calculation of Pressure

The pressure exerted by the water can be calculated using the formula:

Pressure (P) = Density (ρ) × Gravity (g) × Height (h)

Where: - Density of water (ρ) = 1000 kg/m³ - Acceleration due to gravity (g) = 9.81 m/s² - Height of the water column (h) = 1 m

Substituting the given values: Pressure (P) = 1000 kg/m³ × 9.81 m/s² × 1 m

Let's calculate the pressure using these values.
