Is there a law stating that all personal residences have to at least have one fire extinguisher? I am in Texas. I know businesses have to, but does a personal home? I realize that it's always a good idea to have one for safety purposes. If there isn't a law about it, then I wonder why not. What do you think?
she sounds like she really is into you. but at the same time she is very well balanced by trying to handle work and school. if you really like this girl, then you might have to move at her speed for awhile until she makes more time for you
We don't always use dielectric materials in telescopes. In the reflector type telescope, the light is actually reflected off a mirror that's a thin layer of metal spattered on a glass surface. One can also manufacture mirrors made of solid metal (look at your car's bumper). If you are talking about a refractor type telescope (with lenses), the reason is that metals are opaque for practically all frequencies of electromagnetic radiation (including light). If you mean other parts of the telescope, they are not necessarily dielectric at all.
