How are half life and radioactive decay related

Answer : Half life and radioactive decay are inversely proportional to each other.

Explanation :

The mathematic relationship between the half-life and radioactive decay :

             ................(1)

where,

N = number of radioactive atoms at time, t

= number of radioactive atoms at the beginning when time is zero

e = Euler's constant = 2.17828

t = time

= decay rate

when then the number of radioactive decay become half of the initial decay atom i.e .

Now substituting these conditions in above equation (1), we get

By rearranging the terms, we get

Now taking natural log on both side,

By rearranging the terms, we get

This is the relationship between the half-life and radioactive decay.

Hence, from this we conclude that the Half life and radioactive decay are inversely proportional to each other. That means faster the decay, shorter the half-life.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
