Answer:
Differential equation: , , , .
Solution:
Step-by-step explanation:
Let suppose that rate of change of the amount of Carbon-14 atoms are directly proportional to the current amount of Carbon-14 atoms. That is:
Where:
- Amount of Carbon-14 atoms, dimensionless.
- Proportionality constant, measured in .
must be negative as death rate is constant and birth rate is zero. (). Dimensionally, we can rewritte this constant as following:
Where is the time constant (), measured in years.
We can find the solution of the ordinary differential equation by separating each variable:
Where is the initial amount of atoms of Carbon-14.
The correct answer would be 7! Hope I helped!
Yes Kent Did beat the record. There are sixteen ounces in one pound. 16•8=128+3 sooooo..131
Each section of the tree diagram (in this case the branches that say vanilla chocolate and strawberry) must add up to 1
so to answer you should do 0.45+0.35= 0.8
then 1-0.8 =0.2
so Z is 0.2
