Not necessarily. If something brittle were to crash into something hard, it would shatter before it could pass through. On a related note, however, there is a small but non-zero chance that something can pass through something else through quantum tunneling.
Well, technically oxygen molecules do move through a plastic bag, just not fast enough for you to use it in a manner that will help you survive.
S waves can only pass through solids. They cannot pass through liquids (e.g. water, molten rock).
Fast enough.
Not yet. There are no known species that can eat fast enough to keep up with it, so a substrantial portion of the radiation always gets through.
Yes, it is spinning quite fast. Going round in five minutes under 10 hours is very fast for something with ten times the diameter of the Earth. It is not fast enough to make it break up, though.
If fired fast enough, it can either begin orbit (unless/until it hits something else that stops it), or escape Earth's gravity and begin travel through space (again, until it hits something).
Anything above 50 km/h is enough.
centrifugal force
Space junk travels as fast as all material that orbits the Earth or at about 17,500 miles per hour. This is fast enough to do damage to anything the junk encounters in orbit.
Anything but make sure its enough to keep you going the whole day.
Enough to propel the aircraft very fast through the air.
If you recoil your hand fast enough you can punch through glass without marks.
That would also depend on the length of the pipe, and on how fast you want the water to move. If you are in no hurry, even the slightest pressure will be enough to push the water through the pipe.That would also depend on the length of the pipe, and on how fast you want the water to move.

You'd have to stir it up fast enough so that it overflows, or burn it several times by not doing anything.
Fast enough.
