My Kidde hardwired smoke and carbon monoxide detector just recently has started chirping/beeping every minute or so. I have done extensive research, and I'm not getting any answers that are applicable.I replaced the battery several times, and the beeping continued. The detector was installed last year, so is not too old, and I even flicked the breaker switch on and off Nothing works. Please help me out here.
Leave the safety pin or needle in there a while, or you might have the earring right behind your earlobe right as your taking the needle off. Hope it helped
You need a special compression fitting that has either a rubber o-ring or rubber gasket that is compressed around the old pipe as you tighten the fitting. You may have to special order it through your local hardware store.
Gravity distorts space and space is 3d not 2d so I never understood that analogy myself. Think of it like a ball inside of a sponge. The sponge is space and the ball is a planet, The sponge would be more compressed close to the ball and less compressed farther from it, the compressed area is the area were gravity is strongest. This turns out to be a very accurate representation of gravity.
The rubber sheet represents a 3-dimensional curvature in 2-dimensional space. Gravity is a curvature in 4-dimensional space-time. The 4th dimension is time. So what is a curve in space-time? First, imagine a straight line. It's 1-dimensional, and represents no change in direction. A curved line represents a change in direction, into additional dimensions. If that curvature extends into the 4th dimension, which is time, that inherently involves a change in speed, since speed is a function of both space and time. A change in speed is acceleration. So by accelerating, as when pressing the gas pedal in a car, you are tracing a curvature through space-time. With that in mind, gravity is a curvature in space-time itself. Anything that enters a gravitational field must follow that curve, and accelerate. It's analogous to trying to draw a straight line on a curved or bent piece of paper. You can't. Accelerating in a car is like drawing a curved line on a straight piece of paper. Falling into a gravitational field is like trying to draw a straight line on a curved piece of paper. In this way, gravity and acceleration are equivalent, according to Einstein's general theory of relativity. Both are curvatures in 4-dimensional space-time.
