Question

Another example of an exponential decay can be found when studying radioactive materials. These materials have the property that at some point in time their atoms will transform themselves spontaneously into different atoms. This means that if you have a sample of radioactive material that initially contains atoms, the number of original atoms in the sample will decay exponentially with time: for some time constant . Suppose you have a sample of radioactive material that decays with a time constant of 60 . If after 2.0 there are 3.4

Explanation / Answer

N(t)=No*e^(-Rt)
3.4×10^6=No*e^(-60*2)

No=3.4×10^6/e^(-60*2)then u will get ans
