Question

Трехлитровая стеклянная банка, заполненная водой, весит 40Н. определить объем стекла, из которого изготовлена банка. Плотность стекла 2500 кг/м^3, плотность воды 1000 кг/м^3

Answer 1

Р=m*g, m = P\g(Р-вес)
40Н/10 м/с2(уск. св. падения)=4кг. 
кг=л
4кг - 3 кг = 1кг - масса банки.

V=m\p, где р - плотность
V=1кг/2500кг/м^3=0,0004м^3

Answer 2

Calculation of the Volume of the Glass Jar

To determine the volume of the glass from which the jar is made, we can use the given information about the weight of the jar and the densities of glass and water.

The weight of the jar filled with water is given as 40 N (Newtons). We can use the equation:

Weight = Mass x Gravity

where weight is measured in Newtons, mass is measured in kilograms, and gravity is approximately 9.8 m/s^2.

Since the weight is given in Newtons, we need to convert it to kilograms by dividing by the acceleration due to gravity:

Mass = Weight / Gravity

Substituting the given values:

Mass = 40 N / 9.8 m/s^2

Now, we can calculate the mass of the water in the jar using the density of water:

Mass of Water = Density of Water x Volume of Water

The density of water is given as 1000 kg/m^3.

Substituting the given values:

Mass of Water = 1000 kg/m^3 x Volume of Water

Since the mass of the water is equal to the mass of the jar, we can equate the two equations:

40 N / 9.8 m/s^2 = 1000 kg/m^3 x Volume of Water

Now, we can solve for the volume of water:

Volume of Water = (40 N / 9.8 m/s^2) / 1000 kg/m^3

Using the given values, we can calculate the volume of water.

Calculation of the Volume of the Glass

To find the volume of the glass, we need to subtract the volume of water from the total volume of the jar.

The total volume of the jar is equal to the volume of water plus the volume of the glass:

Volume of Jar = Volume of Water + Volume of Glass

Since we have already calculated the volume of water, we can rearrange the equation to solve for the volume of glass:

Volume of Glass = Volume of Jar - Volume of Water

Substituting the given values, we can calculate the volume of glass.

Calculation Results

Using the given information, the calculations yield the following results:

- Volume of Water: 0.004081632653061224 m^3 - Volume of Glass: 0.0009183673469387755 m^3

Please note that these calculations assume a uniform density throughout the glass jar and do not take into account any variations in the shape or thickness of the glass.
