Question

Как узнать вес тела в воде, зная, только вес тела в воздухе?​

Answer 1

Ответ:

Вес тела в воздухе: P = mg . Вес тела направлен вниз.

Архимедова сила: F А = m ж ⋅ g . Сила направлена вверх.

Вес тела в жидкости: P 1 = P − F А = mg − m ж g . Результирующая сил 1 и 2.

How to Determine the Weight of an Object in Water, Knowing Only its Weight in Air?

To determine the weight of an object in water, knowing only its weight in air, you can use the principle of buoyancy. When an object is submerged in a fluid, it experiences an upward force called buoyant force, which is equal to the weight of the fluid displaced by the object. By comparing the weight of the object in air to its apparent weight in water, you can calculate the weight of the object in water.

Here's the step-by-step process:

1. Measure the weight of the object in air using a scale. 2. Submerge the object in water completely. 3. Measure the apparent weight of the object in water using the same scale. 4. Calculate the weight of the water displaced by the object. This can be done by subtracting the apparent weight of the object in water from its weight in air. 5. The weight of the water displaced is equal to the weight of the object in water.

Example: Let's say the weight of the object in air is 50 grams and its apparent weight in water is 40 grams. The weight of the water displaced by the object would be 50 grams - 40 grams = 10 grams. Therefore, the weight of the object in water is 10 grams.

Please note that this method assumes that the density of the object is uniform and that there are no other factors affecting the buoyancy of the object.
