Answer:
The person has been dead for approximately 15,300 years
Explanation:
<u>Available data</u>:
- The half-life of carbon 14 is 5,600 years
- The human skeleton level of carbon 14 is 15% that of a living human
To answer this question we can make use of the following equation
Ln (C14T₁/C14 T₀) = - λ T₁
Where,
- C14 T₀ ⇒ Amount of carbon in a living body at time 0 = 100%
- C14T₁ ⇒ Amount of carbon in the dead body at time 1 = 15%
- λ ⇒ radioactive decay constant = (Ln2)/T₀,₅
- T₀,₅ ⇒ The half-life of carbon 14 = 5600 years
- T₀ = 0
- T₁ = ???
Let us first calculate the radioactive decay constant.
λ = (Ln2)/T₀,₅
λ = 0.693/5600
λ = 0.000123
Now, let us calculate the first term in the equation
Ln (C14T₁/C14 T₀) = Ln (15%/100%) = Ln 0.15 = - 1.89
Finally, let us replace the terms, clear the equation, and calculate the value of T₁.
Ln (C14T₁/C14 T₀) = - λ T₁
- 1.89 = - 0.000123 x T₁
T₁ = - 1.89 / - 0.000123
T₁ = 15,365 years
The person has been dead for approximately 15,300 years
<h2>Answer</h2><h3>1)</h3>
<em>The business owners’ personal assets are protected from liabilities, but the business is not a separate tax entity </em>Limited liability corporation.<em> </em>
Limited liability corporation is not considered separate from its owners for tax purposes.
<h3>2)</h3>
<em>A single individual is personally responsible for all liabilities incurred by the business </em>Sole Proprietorship.
The business is owned and run by one person, and owner and business are considered as a same entity.
<h3>3)</h3>
<em>One business owner may contribute less time and effort than the other, leading to disputes and bitterness </em>Partnership.
The business is owned and run by more the one person which means there is more than one owner.
<h3>4)</h3>

Answer:
As the length of a complete turn of a double helix is 3.4 nm long and each of them contains 10 base pairs, we can determine the distance between two consecutive pairs by simply dividing the length of the complete turn by the number of base pairs in it. The distance 3.410nm i.e. 0.34 nm. Note: Even though E.
