It was an accident the stove was left on and she left to work, nothing actually burned just a little smoke damage but now she is a little sad and depressed. :(
We'd fall out of orbit, but nothing much more, and also there's no such thing as gravity speed.
I did the following to resolve this problem: 1) Take down all the smoke detectors. If you have a CO monitor also hard wired, take it down as well. 2) For each detector, open the battery compartment so that there is no power to the detector. Hold down the test button until all beeping stops to drain the capacitor. The detectors usually have a capacitor that holds some charge even after disconnected from power and battery. 3) Close the battery compartment so that the detector is running on battery alone. If it starts to chirp, repeat with a new battery. If it chirps with a new, good battery, try blowing dust out of the detector and repeating. If it still chirps, get a new detector. 4) Once all detectors are working on battery power, connect them to power one by one. If the detector starts to chirp, then try a different detector in that location. If both chirp you probably have a wiring problem or connector issue at that location. If one chirps but the other does not, you probably have a wiring or connector problem on the chirping detector. I hope this helps. Most of this came from First Alert customer support. They were very helpful.
nope, the acceleration of gravity is 9.81 m/s.
I'm going to disagree with the other answers provided. As far as we can tell, gravity propagates at the speed of light. Certainly our current theories of gravity require/expect this, and it is also an outcome of relativity. In standard current theories, gravity represents the distortion of space-time by large masses. The image provided is usually that of a rubber sheet with masses deforming it, but that raises as many questions as it answers. Nonetheless, you could think of gravity waves rippling through the sheet based on changes in positions and orbits of objects. If you removed the sun via some instantaneous process, the flattening of the sheet would ripple our way for 8 minutes, just like the tail end of light from the sun, and we would discover our loss with the earth becoming dark and moving along a straight line when the light and gravity waves reach us. My only unease with this is that we have not yet successfully measured gravity waves propagating through space-time. We might be able to measure them from various phenomena, like stars orbiting black holes, but we have not yet gotten our instruments sensitive enough to do this.
