Question

СРОЧНО ПОЖАЛУЙСТА!!! вес металлической детали в воздухе равен 4 Н, а при полном погружении в пресную воду 2,4Н. чему равна плотность металла, из которого изготовлена деталь​

Answer 1

Ответ:

9,6H плотность металла мне так кажется

Answer 2

Calculation of Density

To calculate the density of the metal from which the detail is made, we can use the formula:

Density = Force / Volume

Given that the weight of the metal detail in the air is 4 N and the weight of the detail when fully submerged in fresh water is 2.4 N, we can use these values to calculate the density.

Calculation Steps

1. Calculate the volume of the metal detail in the air: - Since the weight of the detail in the air is 4 N, we can use the same value as the force acting on the detail. - The volume can be calculated using the formula: Volume = Force / Density. - Substituting the given values, we have: Volume = 4 N / Density.

2. Calculate the volume of the metal detail in water: - Since the weight of the detail in water is 2.4 N, we can use the same value as the force acting on the detail. - The volume can be calculated using the formula: Volume = Force / Density. - Substituting the given values, we have: Volume = 2.4 N / Density.

3. Equate the two volume equations and solve for density: - Setting the two volume equations equal to each other, we have: 4 N / Density = 2.4 N / Density. - Since the densities are the same, we can cancel out the densities on both sides of the equation. - Simplifying the equation, we have: 4 N = 2.4 N.

Solution

Based on the given information, it seems that there is an error in the provided values. The weight of the metal detail in the air cannot be greater than the weight of the detail when fully submerged in water. Therefore, it is not possible to calculate the density of the metal detail accurately with the given information.

Please double-check the provided values and provide accurate information to calculate the density of the metal detail.
