Carbon dating and logarithms

Did Australian industry “reduce” their emissions a year ahead of the carbon tax? In anticipation of the pointless expense and increased sovereign risk, they may have shut down or moved overseas. During the carbon tax period we “saved” something like 17Mt of CO2.That’s how much less we theoretically emitted compared to what we would have been produced if our emissions had stayed at the annual level they were at in June 2012 (subject to adjustment).If you have two identically functioning clocks, you can start them together, move them to different locations or along different paths, then when you physically bring them back together to compare, they will literally have registered different amounts of time. And , cosmologists are always talking about the age of the universe (a mere 13.80±0.02 billion years young).

Matter that has been in the middle of large galaxies since early in the universe’s history should be no more than on the order of 50,000 years younger than matter that has managed to remain in intergalactic space.Chemists are often interested in how fast a reaction will occur, and what we can do to control the rate.The study of reaction rates is called kinetics, and we will learn about average reaction rate, rate laws, the Arrhenius equation, reaction mechanisms, catalysts, and spectrophotometry.Natasha Glydon Exponential decay is a particular form of a very rapid decrease in some quantity.One specific example of exponential decay is purified kerosene, used for jet fuel.
