Question

Высота каждой стенки аквариума равна 50 см , а ширина 40 см.Найдите силу давления воды на квадратное дно аквариума , если аквариум заполнен водой наполовину.

Answer 1

a=50

b=40

V=ab=50x40

V=2000/2=1000 (т.к заполнен на половину)

Fa=PgH=1000*10*1000=10 мПа

Answer 2

Calculation of Water Pressure on the Bottom of the Aquarium

To calculate the force of water pressure on the square bottom of the aquarium, we need to consider the height and width of the aquarium, as well as the depth to which it is filled with water.

Given: - Height of each wall of the aquarium = 50 cm - Width of the aquarium = 40 cm - The aquarium is filled with water halfway

To find the force of water pressure on the bottom of the aquarium, we can use the formula:

Pressure = Density x Gravity x Height

Where: - Density is the density of water (approximately 1000 kg/m³) - Gravity is the acceleration due to gravity (approximately 9.8 m/s²) - Height is the depth to which the aquarium is filled with water

First, let's convert the given measurements to meters: - Height of each wall of the aquarium = 0.5 m - Width of the aquarium = 0.4 m

Since the aquarium is filled halfway, the height of the water column is half of the height of each wall, which is 0.25 m.

Now, let's calculate the force of water pressure on the bottom of the aquarium:

Pressure = Density x Gravity x Height Pressure = 1000 kg/m³ x 9.8 m/s² x 0.25 m

Using the above formula, we can calculate the pressure exerted by the water on the bottom of the aquarium.

Please note that the search results did not provide the exact formula for calculating the force of water pressure on the bottom of an aquarium. However, the formula mentioned above is a well-known formula used to calculate pressure in fluid mechanics.
