translucent
Material with low conductance such as rubber, plastics and so forth.
Sound can travel through all matter. The speed at which it travels depends on the density of the material.

It reflects off of the object, and this is the light we see when we view opaque objects; it can be absorbedby the object, and we do not see this light; or the light can pass through the object in such a way that we can clearly 'see through' the object, such as transparent glass, or light can pass through the object and only appear as a glow, not an image, as is the case with some types of translucent plastic, frosted glass or other kinds of material.

Small objects that can be carried in the magnetic current.

That has a few names. It can be a clogged artery, blocked artery, and other names. The material that blocks the artery is usually fat, though blood clots can form in arteries. This is very dangerous. It can cause all kinds of problems, and not just heart problems. If an artery in your brain is blocked, you can die within minutes because of lack of oxygen to the brain. If it happens in the artery leading to the lungs, the same may happen. This can be prevented by eating less junk food and exercising.
If the other material is magnetized, then yes.
