Nothing good. Go to the vet immediately.
''That protruding metal rod could impale someone''
No, stomach acid cannot melt metal. Stomach acid, or hydrochloric acid, is strong enough to break down food for digestion, but it is not powerful enough to melt metal. Metal requires much higher temperatures to melt.
A metal object designed to cut flesh, such as a knife or blade, could be considered a "flesh-eating" object. These objects are typically sharp and capable of causing injury or harm to living tissue.
A thumbtack is a small metal object that consists of a parabola with a short, pointy metal spike protruding from its vertex. It is used to temporarily affix paper to an appropriate surface, especially a bulletin board. It recent years, its popularity has waned and it has largely been replaced by pushpins, which are similar objects with a different shape that use more plastic than metal.
Metal has a metallic luster and is a conductor.
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
Not in its body but in its "hardware stomach" the reticulum. In short, yes. Hardware disease can result with metal in the reticulum; Hardware disease happens when a sharp foreign object such as wire or a nail penetrates the gut lining, resulting in infection as the bacteria from the digestive tract gets into this wound in the gut. The only way to prevent this is to orally insert a strong magnet into the cow's stomach to collect the metal that has collected there and keep the metal away from the stomach lining. The magnet is in the stomach throughout the cow's life. To prevent any hardware disease or any cattle swallowing any pieces of metal it is best to go through the pasture on walks and pick up any nails, pieces of wire, or any other scrap of metal that the animals could swallow. Purchasing hay with no metal in it helps too.
all of the answers are correct
[object Object]
The electrons in the metal object are repelled by the negatively charged object and will move away from it. This redistribution of electrons can create a temporary separation of charges on the surface of the metal object.
You could burnish any metal object, like a trophy or cutlery, a door knob or anything like that.
In order to know what a metal object is on a dorm wall one would need more information. If a description of the metal object is given one may be able to determine what the object is.
