Question

Кусок дерева плавает в воде , погрузившись на 3/4 своего объёма . Какова плотность дерева ?

Answer 1

объем дерева множим на плотность дерева, с одной стороны, и это равно 3/4 объема дерева, помноженному на плотность воды, итого плотность дерева равна 0.75 плотности воды

Answer 2

750 кг на м в кубе.
Или будет равна трем четвертой плотности воды 

Answer 3

Calculating the Density of the Wood

To calculate the density of the wood, we can use the formula: density (ρ) = mass (m) / volume (V).

Given that the wood is floating in water and has submerged to 3/4 of its volume, we can use the information provided in the search results to calculate its density.

Using the information from the search results, we can calculate the density of the wood as follows:

Step 1: Calculate the submerged volume of the wood. Step 2: Use the submerged volume to calculate the mass of the wood. Step 3: Finally, calculate the density of the wood using the mass and the total volume.

Calculation Steps

Step 1: Calculate the submerged volume of the wood. The submerged volume of the wood is 3/4 of its total volume.

Step 2: Use the submerged volume to calculate the mass of the wood. The mass of the wood can be calculated using the formula: m = ρ * V.

Step 3: Finally, calculate the density of the wood using the mass and the total volume. The density (ρ) of the wood can be calculated using the formula: ρ = m / V.

Conclusion

By following these steps, you can calculate the density of the wood based on the given information.
