I have a front wheel drive Toyota Matrix, 2005. Every winter my car fishtails all over the place no matter how slow I go, and hills are pretty much impossible. I've been told to put my snow tires in the back I've been told to put them in the front Where should I put my snow tires? Is it possible I need 4 snow tires? Or just the 2? If 2, where should they go???
That's what's known as a lens flare. Usually happens when your taking a picture of someone too close or your too close to a wall, or reflective materials such as glass, so that when the light from the camera flashes it gets reflected back onto the camera lens or glass cover. Try moving farther away from the subject or wall. Try cleaning the glass covering the lens with cotton/soft cloth as moisture/oily substance like sweat can also cause this. Be careful not to scratch it.
Yes. It is safe or it would never have been permitted. Americium is the only synthetic element to have found its way into the household, where one common type of smoke detector uses 241Am in the form of americium dioxide as its source of ionizing radiation. This isotope is preferred against 226Ra because it emits 5 times more alpha particles and relatively little of harmful γ-radiation. The amount of americium in a typical new smoke detector is 1 microcurie (37 kBq) or 0.28 microgram.
