Check the Benjamin line of air guns at www.crosman.com. Benjamin make metal air guns. Also there is no such thing as BB bullets. BB's and pellets are fired from Air guns.
Gun powder or air
Airguns normally shoot metal pellets. A rifle cargridge has a built-in gunpowder charge to propel the bullet when the powder explodes. An airgun compresses air in a chamber, when you pull the trigger the air is released and takes the pellet with it.
air and gun powder are the most common.
No! they are powered bu Air or C02 that fires a Pellet or BB but NO gunpowder is involved. Hence they are called "air guns."
As a very general rule, bullets are propelled by burning powder, pellets by air or C02
White powder of aluminum oxide
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
A material that spontaneously ignites in air below 113°C (45°C), such as fine metal powder, alkali metal, partially or fully alkylated metal or nonmetal hydride, and metal carbonyl
I think you mean pellet gun. That is a gun that fires a small lead pellet but does not use gun powder. It uses compressed air or compressed gasses to push the pellet.
There is only one rifle described in the question and it travels 0 m. nice try. The whole question is shown below: An observer stands 26 m behind a marksman practicing at a rifle range. The marksman fires the rifle horizontally, the speed of the bullets is 790 m/s, and the air temperature is 20°C. How far does each bullet travel before the observer hears the report of the rifle? Assume that the bullets encounter no obstacles during this interval, and ignore both air resistance and the vertical component of the bullets' motion.
There are two types of air guns. One is a tool that is driven by a compressor rather than by hand. It is used to remove/install nuts and bolts on equipment. The other is an air gun like a real gun that fires a projectile, that is driven by gas or compressed air rather than gun powder.
