Question

В сосуд налили слой воды высотой 25 см.Какое давления этого слоя на дно сосуда?Ускорения свободного падения считать как 10H/кг.Ответа дайте в Па

Answer 1

Ответ:

Дано:

h=15 см=0.15 м

ρ(H2O)=1000 кг/м^3

g=9,8 м/с^2

Решение:

В соответстии с формулой p=ρ*g*h, находим p

p=1000*9,8*0,15=1470 Па

Ответ:1470 Па.

Answer 2

Calculating Pressure Exerted by the Water Layer

To calculate the pressure exerted by the water layer at the bottom of the vessel, we can use the formula:

Pressure (P) = Density (ρ) × Acceleration due to gravity (g) × Height (h)

Given: - Height of the water layer (h) = 25 cm = 0.25 m - Acceleration due to gravity (g) = 10 m/s^2

Using the formula, we can calculate the pressure.

Calculation

Density of water (ρ): The density of water is approximately 1000 kg/m^3.

Pressure (P): Using the given values and the formula: P = ρgh

Substitute the values: P = (1000 kg/m^3) × (10 m/s^2) × (0.25 m)

Result

P = 2500 Pa

Therefore, the pressure exerted by the water layer at the bottom of the vessel is 2500 Pascal (Pa).
