Question

Помогите пожалуйста! чему равна сила давления бензина на дно сосуда прямоугольной формы,если длинна дна равна 20см ширина 30см и высота 80см(плотность керосина 710кг/м³​

Answer 1

Ответ:

Объяснение:..........

Answer 2

Ответ:

Сила давления 340 Н

Объяснение:

Дано:

a = 20 см = 0,20 м

b = 30 см = 0,30 м

h = 80 см = 0,80 м

ρ = 710 кг/м³

______________

F - ?

1)

Давление бензина на глубине h:

p = ρ·g·h = 710·10·0,80 = 5680 Па

2)

Площадь дна сосуда:

S = a·b = 0,20·0,30 = 0,060 м²

3)

Сила давления на дно сосуда:

F = p·S

F = 5680·0,060 ≈ 340 Н

Answer 3

Calculating Pressure Exerted by a Liquid

To calculate the pressure exerted by a liquid at the bottom of a container, we can use the formula:

Pressure = Density × Acceleration due to gravity × Height

Where: - Density is the density of the liquid (in this case, the density of kerosene is given as 710 kg/m³). - Acceleration due to gravity is the acceleration experienced by an object due to the gravitational pull of the Earth (approximately 9.81 m/s² near the Earth's surface). - Height is the vertical distance from the surface of the liquid to the bottom of the container.

Applying the Formula

Given: - Length of the base (l) = 20 cm = 0.2 m - Width of the base (w) = 30 cm = 0.3 m - Height of the container (h) = 80 cm = 0.8 m - Density of kerosene = 710 kg/m³ - Acceleration due to gravity = 9.81 m/s²

We can calculate the pressure exerted by the kerosene at the bottom of the container using the formula mentioned above.

Pressure = Density × Acceleration due to gravity × Height

Pressure = 710 kg/m³ × 9.81 m/s² × 0.8 m

Let's calculate the pressure using the given values.
