Answer:
This is a feverish body temperature.
Explanation:
hope it is okay.
It would be considered a Homogeneous Mixture. A mixture with two or more components mixed evenly is a Homogeneous mixture.
The correct way to write this number in scientific notation : 6.022 x 10²³
<h3>Further explanation
</h3>
Scientific Notation is a standard form of writing numbers used in mathematical operations
The rules:
1. Writing order : first digit, decimal point, next digit
2. Then followed by powers of 10 (the value can be +/-)
If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit
If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit
I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.
And the right ones are: 6.022 x 10²³
This question is dealing with the half-life of carbon-14 which can be used to determine the age of a substance according to the following equation:
t = [ln(N/No)/(-ln2)] · t1/2
N = # of carbon-14 atoms presently = 250 atoms
No = # of carbon-14 atoms initially = 1000 atoms
t1/2 = half-life = 5730 years for carbon-14
We can now input all of the information into the formula to find the age of the fossil:
t = [ln (250/1000)/-ln2] x 5730 years
t = 11460 years
The fossil should be found to be roughly 11,460 years old.
The answer for the first question is A. Iced Tea and C. Orange Juice. The answer for the second question is A. Heterogeneous mixture
A homogeneous mixture is a combination of 2 or more substances wherein its concentration is evenly distributed throughout the mixture. This means that you cannot identify the different components or properties of the mixture. A heterogeneous mixture, on the other hand, is a combination of 2 or more substances wherein its components are unevenly distributed. This means that its components can visibly be identified from each other.
