Bullet works 1

🤔 How it works ……..

How a bullet works… 🔫

When you pull the trigger of a gun, a spring mechanism hammers a metal firing pin into the back end of the cartridge, igniting the small explosive charge in the primer. The primer then ignites the propellant—the main explosive that occupies about two thirds of a typical cartridge’s volume. As the propellant chemicals burn, they generate lots of gas very quickly. The sudden, high pressure of the gas splits the bullet from the end of the cartridge, forcing it down the gun barrel at extremely high speed (300 m/s or 1000 ft/s is typical in a handgun).

What adaptations allow the frog to live on land and in water?

Frogs start their lives as aquatic tadpoles with gills to breathe. As tadpoles grow into frogs, lungs replace the gills and allow frogs to breathe on land. Frogs’ skin is covered by a layer of slime that dissolves oxygen from air and water. Numerous blood vessels present in frogs’ thin skin absorb the oxygen.
