Every chemical element goes through natural exponential decay, which means that over time its atoms fall apart. The speed of eac
yKpoI14uk [10]

Answer:

t = ln (N/N°)/(-0.0239)

Explanation :

The decay law is represented as

N = N°e^-kt

Where N is the final number of atom,

N° is the initial number of atoms

k is the decay constant

t is the half-life.

From the above we have,

N/N° = e^-kt

take ln of both sides

ln (N/N°) = -kt

t = ln(N/N°)/-k

At half life, N/N° = 1/2

Therefore, t = (ln 1/2)/-k

t = -0.693/-k

But t = 29 sec

29 = -0.693/-k

k = 0.0239 s^-1

Therefore,

The formula will be

t = ln (N/N°)/(-0.0239)
