You are entering the sea, lake or river. How does the Archimedean force acting on you change?

The buoyancy force acting on a submerged body in a liquid, according to Archimedes’ law, is equal to the product of the density of the fluid and the acceleration of gravity and the volume of the submerged part of the body. In our case, when entering water, the volume of the body and the acceleration of gravity on Earth are constant, while the density of fresh water in a lake or river (= 1000 kg / m ^ 3) is less than the density of seawater (= 1300 kg / m ^ 3) , from the directly proportional dependence of the Archimedes force on the density of the liquid, it follows that when entering the sea, the buoyant force acting on a person will be greater.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
