Answer:
Explanation:
First of all, we can find the speed of the sound wave, which is given by:
where
f = 645 Hz is the frequency
is the wavelength
Substituting,
Now we can find the temperature of the air by using the following relationship:
where T is the temperature in Celsius degrees. Since we know v = 322.5 m/s, we can re-arrange the formula to find the temperature:
Only make changes to the experimental setup when the circuit power is turned off and all power sources read zero voltage and zero current, as applicable.
Answer:
The total permutation = nP2
The inversions = nC2

<span>Yes it is possible to distiguish between an element and a compound. An element is any one of the over 100 things you can see on the periodic table. like say .F or H. Those are element. Another example C or O. when you put CO together you would get Carbon monoxide and that would be an element. Just know that if you see one of the symbols just as how they would look on the periodic table then it is not a compound. It has to be with another element</span>
Rutherford's model did not completely reimagine Thomson's. Like Thomson, Rutherford still believed that atoms contained negatively charged electrons. Unlike the plum pudding model, where those atoms simply floated in "soup," Rutherford believed they orbited the central nucleus just as planets orbit the sun.
