Magnetic Induction Applications

The main application of magnetic or electromagnetic induction is its use in obtaining energy. Currently all power plants use induction studies as a way of working as it is an efficient way and has several ways to be put into practice. Another great use of this branch of physics is in the development of transformers and self-transformers, which are increasingly improved and their use is already fundamental in almost all major industries.

What floats and what sinks in water

Why do some bodies sink and others float in water? Let's look at some examples. Water and oil do not mix. When a ship leaks oil, it causes major damage to nature. This is because oil does not sink. It floats on water, not allowing the passage of light essential for marine life. If we put water in a container and inside it a piece of iron (nail), this iron will sink.

Factors that change the speed of chemical reactions (continued)

Catalyst Catalyst is a chemical that does not participate in the chemical reaction. Decreases activation energy and increases reaction speed. The catalyst accelerates the reaction but does not change the chemical composition of the reagents and products involved. The amount of substance produced in the reaction does not change with the use of catalysts.

Hydrostatic

Hydrostatic pressure Like solid bodies, fluids also put pressure on others because of their weight. To obtain this pressure, consider a vessel containing a liquid of density d that occupies the vessel up to a height h at a place on the planet where the acceleration of gravity is g.
