Question

Почему тело всплывает?​

Answer 1

Ответ:

Тело всплывает в воду, если сила Архимеда уравновешивает силу тяжести тела.

Answer 2

Why Do Bodies Float?

When an object, including the human body, floats in water, it's due to a principle known as buoyancy. Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. This force is the result of the difference in pressure between the top and bottom of the object.

The reason why some objects float while others sink is determined by their density. If an object is less dense than the fluid it's placed in, it will float. Conversely, if it's denser, it will sink.

In the case of the human body, it generally contains a significant amount of air in the lungs and various internal spaces. This air increases the body's overall volume and decreases its density, making it more likely to float.

The Archimedes' principle provides a more detailed explanation. This principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. When the weight of the displaced fluid is greater than the weight of the object, the object will float.
