Discuss ways of altering the rate of decay
WebThe decay rate formula can be expressed mathematically as: A= -dN/dt= λ N. The decay rate algorithm can be expressed as: y = a ( 1-r)t. here y= final amount of the radioactive element left. a= initial amount of the radioactive element. r= rate of … WebMar 21, 2016 · Analysing the chemical composition of the soil can determine if it is acidic or alkaline, or if the pH levels are unusual. The type of soil a body is buried in can alter its rate of decomposition—acidic soil can cause a body to …
