Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730
Largest energy found in the lowermost portion of the trophic level near "Producers" 'cause as it passes through the higher trophic levels, it get decreased by 10% at each step, according to Lindmann's 10% law!!
Hope this helps!!
The three parts that make up paint are pigments, binders and solvents. Pigments consist generally of organic and non-organic compounds and materials that are added to paint to produce a particular color.<span> Binders are substances that provide support or structure for the pigment and solvents to work. Solvents work to dissolve or disperse these substances into liquid form.

Answer:
When energy flows out of a system, it must all flow into the surroundings.
When energy flows out of a system, ΔEsystem is negative.
When energy flows into the surroundings, ΔEsurroundings is positive.
Therefore,
─ ΔEsystem= ΔEsurroundings
