Question

Ящик с погруженным объемом 0,002 м2 находится в неизвестной жидкости. Рассчитайте плотность жидкости и определите, какой она будет как жидкости, если на ящик действует сила Архимеда 16Н.

Answer 1

Объяснение:

F(А) = pgVпч => p = F(A)/gVпч

p = 16/10*0,002 = 800 (кг/м^3) - керосин

Ответ: p = 800 кг/м^3

Answer 2

Calculation of Liquid Density and Identification

To calculate the density of the unknown liquid and determine its identity, we can use the principles of Archimedes' principle. Archimedes' principle states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

Given: - Submerged volume of the box (V) = 0.002 m^3 - Buoyant force acting on the box (F_Archimedes) = 16 N

To calculate the density of the liquid, we can use the formula:

Density (ρ) = Buoyant force (F_Archimedes) / Gravitational acceleration (g) / Volume (V)

The gravitational acceleration (g) is approximately 9.8 m/s^2.

Let's substitute the given values into the formula:

Density (ρ) = 16 N / (9.8 m/s^2) / 0.002 m^3

Calculating this expression will give us the density of the liquid.

Now, to identify the liquid based on its density, we can compare the calculated density with the known densities of various liquids. Different liquids have different densities, so by comparing the calculated density with known values, we can determine the identity of the liquid.

Unfortunately, the search results provided by You.com do not contain specific information about the density of the liquid or its identity. Therefore, we cannot provide a definitive answer based on the available information.

If you have any additional information or specific properties of the liquid, we can try to provide a more accurate answer.
