Answer:
half-life=T= 36.9 years
Explanation:
As we know that
N

=

^(t/

N

=the number of atoms you start with=20 gram
and N
(
t
)= the number of atoms left=0.625 grams
after a certain time=t=184.5 years
T=half life of a nuclide=?
Putting value in above equation we get
half-life=T= 36.9 years

The subsurface process is composed of a series of complex geologic processes, hence, it's modeling can only best be undertaken by a team of professionals from each of the relevant majors.
Modeling the earth's interior requires the expertise of geophysicsts in using geophysical techniques to obtain subsurface readings at various depths, seismologist obtains and interpretes arrival <em>times of seismic waves</em>, petrophysicst evaluates subsurface properties using log data and so on.
Therefore, the complexity of the subsurface makes it imperative that professionals collaborate in other to come up with an accurate model.
