Half-Life Formula It is the time requires to decay in half. Half-life is the time required for the amount of something to fall to half its initial value. The mathematical representation of Half life is given by, (Half life time) = (Napierian logarithm of 2)/(disintegration constant) The...
Example 4 Solving the Doubling Time Formula World population doubled in the 40 years from 1960 to 2000. What was the average percentage growth rate during this period? Contrast this growth rate with the 2000 growth rate of 1.4% per year. Now...

Half-life formula We can determine the number of unstable nuclei remaining after time tt using this equation: N(t)=N(0)×0.5(t/T),N(t)=N(0)×0.5(t/T), Where: N(t)N(t) –Remaining quantity of a substance after time tt has elapsed; N(0)N(0) –Initial quantity of this ...
Half life formula- The time taken for half of reactions to complete or the time at which the concentration of the reactant is reduced to half of its original value is called the half life period of the reaction. To learn more about the half life formula

Half life formulas Use the appropriate half life formula for the case described below. Discuss whether the formula is valid for the case described. Poaching is causing a population of zebras to decline by 8% per year. What is the half life of the population? If there are 10,000 zebras to...
The formula for half – life is given as Here, N(t)= quantity of substance remaining No= initial quantity of an element λ= decay constant t1/2= half life t = mean life time Mean Life The mean-life of radioactive elements is expected to be slightly more than half-life. If, for a...
