Question

Кубик из жести с ребром 10 см весит 4.ньютона.Какова толщина жести?

Answer 1

Зная вес, найдём массу кубика:

P = mg

m = P / g = 4 / 10 = 0.4 кг

Найдём затем объём кубика. Это можно сделать, зная плотность жести. По таблице смотрим и : p = 7800 (жесть - это сталь вроде бы).

V = m / p = 0.4 / 7800 = 0.00005 м³

Объём кубра расчитывается по формуле:

V = abc

Отсюда b = 0.00005 / 0.01 = 0.005 м

 

Answer 2

Calculating the Thickness of the Metal Cube

To calculate the thickness of the metal cube, we can use the formula for the weight of an object:

Weight = Volume × Density × Acceleration due to gravity

Given: - Weight = 4 Newtons - Side length of the cube = 10 cm

First, we need to calculate the volume of the cube, which is given by:

Volume = Side length × Side length × Side length

Let's calculate the volume of the cube: ``` Volume = 10 cm × 10 cm × 10 cm Volume = 1000 cm³ ```

Next, we can calculate the density of the metal cube using the given weight and volume: ``` Density = Weight / (Volume × Acceleration due to gravity) Density = 4 N / (1000 cm³ × 9.8 m/s²) # Converting cm³ to m³ Density ≈ 0.00040816326531 kg/cm³ ```

Now, we can calculate the thickness of the metal cube using the density of the metal: ``` Thickness = Weight / (Area × Density) ```

However, the area of the cube's face is needed to calculate the thickness. Unfortunately, the search results provided do not contain the specific information required to calculate the thickness of the metal cube. Therefore, without the area of the cube's face, it is not possible to calculate the thickness with the given information.

If you have the area of the cube's face, please provide it, and I can help you calculate the thickness using the given weight and density.
