Question

5. В емкость длиной 60 см и шириной 30 см налита ртуть до высоты 40 см. Определите массу налитой ртути. Плотность ртути составляет 13600 кг/м³

Answer 1

Ответ:

979 200 кг

Объяснение:

находим объем: 60•30•40=72 000 (см³)=72 м³

находим масу через формулу р(ро)=m/V; m=p•V:

m=13 600 кг/м³• 72 м³=979 200 кг

Answer 2

I will answer in detail. 5. A container with a length of 60 cm and a width of 30 cm is filled with mercury to a height of 40 cm. Determine the mass of the mercury poured. The density of mercury is 13600 kg/m³.

To solve this problem, we need to find the volume of the mercury in the container, and then multiply it by the density of mercury to get the mass. The volume of the mercury is equal to the product of the length, width, and height of the container, since it is completely filled. Therefore, the volume of the mercury is:

V = 60 cm * 30 cm * 40 cm = 72000 cm³

To convert the volume from cubic centimeters to cubic meters, we need to divide it by 1000000, since 1 m³ = 1000000 cm³. So, the volume of the mercury in cubic meters is:

V = 72000 cm³ / 1000000 = 0.072 m³

Now, we can multiply the volume by the density of mercury to get the mass:

m = V * ρ = 0.072 m³ * 13600 kg/m³ = 979.2 kg

Therefore, the mass of the mercury poured into the container is 979.2 kg.
