2.38×10^-3
Explanation:
from the question,the we calculate the latent heat of vaporization with the difference in temperature being put into consideration
Answer:
![Precision = 2.70 \± 0.1\ cm](https://tex.z-dn.net/?f=Precision%20%3D%202.70%20%5C%C2%B1%200.1%5C%20cm)
Explanation:
Given
The data in the table
Required
Follow the steps appended to the question;
Step 1: Calculate the Mean or Average
Mean = Summation of lengths divided by number of teams;
![Mean = \frac{2.65 + 2.75 + 2.80 + 2.77 + 2.60 + 2.65 + 2.68}{7}\ cm](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B2.65%20%2B%202.75%20%2B%202.80%20%2B%202.77%20%2B%202.60%20%2B%202.65%20%2B%202.68%7D%7B7%7D%5C%20cm)
![Mean = \frac{18.9}{7}\ cm](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B18.9%7D%7B7%7D%5C%20cm)
![Mean = 2.70\ cm](https://tex.z-dn.net/?f=Mean%20%3D%202.70%5C%20cm)
Step 2: Get The Range
![Range = Highest - Lowest](https://tex.z-dn.net/?f=Range%20%3D%20Highest%20-%20Lowest)
![Range = 2.80cm - 2.60cm](https://tex.z-dn.net/?f=Range%20%3D%202.80cm%20-%202.60cm)
![Range = 0.2\ cm](https://tex.z-dn.net/?f=Range%20%3D%200.2%5C%20cm)
Step 3: Divide Range by 2
![Approximate\ Range = \frac{1}{2}Range](https://tex.z-dn.net/?f=Approximate%5C%20Range%20%3D%20%5Cfrac%7B1%7D%7B2%7DRange)
![Approximate\ Range = \frac{1}{2} * 0.2\ cm](https://tex.z-dn.net/?f=Approximate%5C%20Range%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%200.2%5C%20cm)
![Approximate\ Range = 0.1\ cm](https://tex.z-dn.net/?f=Approximate%5C%20Range%20%3D%200.1%5C%20cm)
Step 4: Determine the Precision
![Precision = Average \± Approximate\ Range](https://tex.z-dn.net/?f=Precision%20%3D%20Average%20%5C%C2%B1%20Approximate%5C%20Range)
Substitute 2.70 for Average and 0.1 for Approximate Range
![Precision = 2.70 \± 0.1\ cm](https://tex.z-dn.net/?f=Precision%20%3D%202.70%20%5C%C2%B1%200.1%5C%20cm)

Answer:plz brainly me;)
Your answer is "A" Conductors
Nonmetals include common gasses that are found in the atmosphere, such as nitrogen and oxygen, as well as sulfur (S) and carbon too. Nonmetals are usually not good conductors of heat and electricity.
A trustable source was above to say that the first experiments will decide how many isotopes of this element exist. Isotopes are atoms of an element which bear chemically the identical but have dissimilar physical properties. One adaptable property among isotopes is their atomic mass.
