oxides of iron are formed
Yes
Should Earth ever collide with a black hole, it would get destroyed.
A blackhole is formed in our universe when matter falls onto the black hole and that forms an accretion disk that is heated by friction. The black hole does not allow anything to escape it.
Material in a quasar is ejected away from the black hole, but that material never crosses the event horizon. Nothing that crosses the event horizon can ever escape.
Yes.
The sheet expands outwards as well
The hole decreases due to metal expansion.

A plasma cutter.
drill small hole in old seal use sheet metal screw drill small hole in old seal use sheet metal screw
use a punch press or drill it
Blanking and punching are both shearing operation. The difference is only in the scrap. In blanking what you cut out is of interest.In punching what you cut from is of interest.For example: You cut a hole in a sheet metal. If you are interested in the disc that is cut out, then the process is called blanking. The sheet metal with a hole through it is the scrap. If you are interested in the sheet metal that now has a hole through it, then the process is called punching. The disc is the scrap.
A fusible plug is a metal cylinder that has been threaded with a hole drilled throughout it. The plugs can be found in a variety of metals. Heated metal is used to seal the hole.
If the hole is very small the material you are brazing with should fill it. A small piece sheet metal can be brazed in place to cover larger holes.
If a hole has been drilled in a metal sheet, the round file is used in the created hole to remove rough edges.
Only if you can cut a hole in the sheet metal.
