Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years

Where, k is rate constant
So,


The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





So,
<u>The rock is 3.75 billion years ago.</u>
There are ADVANTAGE of legalizing baby bins or baby hatches which are typically used to leave the newborn babies by their parent who do not want them for certain reasons and abandon them there.
This can save many lives of the newborns as the other way people might choose is killing the babies or abandoning them at places where no one might ever find them.
The baby left there will have a positive opportunity to flourish in the society unlike the one left at street as the hatches are monitored by law.
There can be some DISADVANTAGES as well to the scheme as it might help promote immoral behaviors in society. A key factor in stopping immoral activities is the fear of society, and baby bins remove that fear. Another risk can be of an increasing tendency of rapes where people might think its OK to give birth to children and then leave them to baby bins.
