Yes, they can only be stopped (even then not completely) by several centimetres of lead.
Try to spell properly next time, it's only 3 extra letters!
a grid is a device placed in front of the image receptor which only allows xrays to travel directly through from the tube and prevent xrays which have been "scattered" from passing through to the image. This gives a much clearer resulting image. Grids are generally only used on thicker body parts where scattered xrays are more of an issue
no.

Yes.
Yes, all xrays travel at the speed of light.
It can travel through things like: Water Wood Metal Hole (like in card board paper)
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
Sound waves need matter to travel through, and wood is matter, so yes, sound waves travel through wood. They travel through wood faster than they do through air, as wood is denser than air.
radiolucent allows x-ray pass through radiopaque does not allow it to pass through
Yes you can very clearly and its just so amazing!
Yes, because methylated spirits have a lower surface tension and viscosity compared to water, they are likely to travel through filter paper faster due to their ability to penetrate and absorb more easily.
No, X-rays do not travel at the speed of sound. X-rays are a form of electromagnetic radiation that travel at the speed of light, which is much faster than the speed of sound.
