About half of most soils are inorganic materials, such as the products of weathered rock, including pebbles, sand, silt, and clay particles. The organic materials are necessary for a soil to be fertile. The organic portion provides the nutrients, such as nitrogen, needed for strong plant growth.
<u>Answer:</u> The sample of Carbon-14 isotope is 37056.3 years old
<u>Explanation:</u>
The equation used to calculate rate constant from given half life for first order kinetics:

where,
= half life of the reaction = 5720 years
Putting values in above equation, we get:

Rate law expression for first order kinetics is given by the equation:
![k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA_o%5D%7D%7B%5BA%5D%7D)
where,
k = rate constant = 
t = time taken for decay process = ? yr
= initial amount of the sample = 100 grams
[A] = amount left after decay process = (100 - 88.5) = 11.5 grams
Putting values in above equation, we get:

Hence, the sample of Carbon-14 isotope is 37056.3 years old

Answer:
C is the answer they are looking for but clearly the truth is D
Explanation:
3 zots = 7 wots
3 zots × (3 dooms/2 zots) = ⁹/₂ dooms
⁹/₂ dooms × (7 farzes/4 dooms) = ⁶³/₈ farzes
⁶³/₈ farzes × (4 bings/9 farzes) = ⁷/₂ bings
⁷/₂ bings × (2 wots/1 bing) = 7 wots
