how far can sound go on for
There is no limit to how far sound can go, as long as there is a matter-containing "medium" for it to pass through. It just gets weaker as it goes farther from the source. It cannot leave the atmosphere, because there is no matter beyond it.
waht is cell ? how is it place in human body ? n use of it?
