Question

Тело массой 500 г при полном погружении вытесняет 600 см3 жидкости. Будет ли оно плавать в воде? В керосине? Срочно

Answer 1

Если тело при полном погружении вытесняет 600 см^3 жидкости, значит, что тело имеет такой же обьем.

Находим плотность по формуле плотность=масса/обьем

$p = m \div V= 500 \div 600 = \dfrac{5}{6}$

(p - плотность, размерность г/см^3).

Плотность воды 1 г/см^3, поскольку тело имеет плотность меньше, следовательно, он будет плавать.

А вот плотность керосина 0,8 г/см^3, поскольку у тела плотность больше, оно будет тонуть в керосине

Answer 2

Ответ:

В воде да.

Объяснение:

В керосине нет т.к. m=500 гр, V=600 см 3, p=m/V=500/600=0,833 гр/см 3. плотность воды 1 гр/см 3> 0,833 плавает, плотность керосина 0,8 гр/см 3 < 0,833 (он не поплывет).

Answer 3

Will the 500g body float in water?

To determine if the 500g body will float in water, we need to compare the density of the body with the density of water. If the density of the body is less than the density of water, it will float; if it is greater, it will sink.

The density of an object can be calculated using the formula:

Density = Mass / Volume

Given that the mass of the body is 500g and it displaces 600cm3 of liquid, we can calculate its density as follows:

Density = 500g / 600cm3

To determine if the body will float in water, we need to compare its density with the density of water, which is approximately 1g/cm3.

If the density of the body is less than 1g/cm3, it will float in water. If it is equal to or greater than 1g/cm3, it will sink.

Let's calculate the density of the body:

Density = 500g / 600cm3 = 0.83 g/cm3

Since the density of the body (0.83 g/cm3) is less than the density of water (1g/cm3), the body will float in water.

Will the 500g body float in kerosene?

To determine if the 500g body will float in kerosene, we need to compare the density of the body with the density of kerosene. If the density of the body is less than the density of kerosene, it will float; if it is greater, it will sink.

The density of an object can be calculated using the formula:

Density = Mass / Volume

Given that the mass of the body is 500g and it displaces 600cm3 of liquid, we can calculate its density as follows:

Density = 500g / 600cm3

To determine if the body will float in kerosene, we need to compare its density with the density of kerosene, which is approximately 0.8g/cm3.

If the density of the body is less than 0.8g/cm3, it will float in kerosene. If it is equal to or greater than 0.8g/cm3, it will sink.

Let's calculate the density of the body:

Density = 500g / 600cm3 = 0.83 g/cm3

Since the density of the body (0.83 g/cm3) is greater than the density of kerosene (0.8g/cm3), the body will sink in kerosene.

Please note that these calculations assume that the body is a solid object and that there are no other factors, such as surface tension or buoyancy forces, affecting its ability to float.
