Question

Когда тело опустили в мензурку с водой,часть его погрузилась.при этом уровень воды поднялся с отметки 20см в кубе до отметки 120см в кубе.чему равна масса тела?

Answer 1

120/20= 6(см) опустили

Answer 2

Calculation of the Body's Mass

To calculate the mass of the body, we can use Archimedes' principle, which states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. In this case, the body is submerged in water, so the buoyant force acting on it is equal to the weight of the water displaced.

According to the information provided, when the body was submerged in a measuring cylinder filled with water, the water level rose from 20 cm to 120 cm. This means that the body displaced 100 cm³ (or 100 mL) of water.

To find the mass of the body, we need to know the density of water. The density of water is approximately 1 g/cm³.

Therefore, the mass of the body can be calculated as follows:

Mass of the body = Density of water × Volume of water displaced

Mass of the body = 1 g/cm³ × 100 cm³

Mass of the body = 100 g

So, the mass of the body is 100 grams.

Please note that the accuracy of this calculation depends on the assumption that the density of water is constant and equal to 1 g/cm³. Additionally, the information provided does not specify the shape or composition of the body, which could affect the accuracy of the calculation.
