Answer:
I think it's 2 the photo is hard to tell what they are exactly talking about.
You would convert from grams to
moles by using the molar mass of the substance. The answer is letter B. for
example, the molar mass Carbon dioxide is 44.01 g/mol. It means that for 1 mole
of carbon dioxide, it contains 44.01 grams of Carbon dioxide.
Answer:
12.0 V
Explanation:
Data :
Potential difference due to a single charge (+Q), E = 3.0 V
The Electric potential for the system of charges is given as:
![E=\frac{1}{4\pi \epsilon_o}[\Sigma\frac{Q}{r}]](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B1%7D%7B4%5Cpi%20%5Cepsilon_o%7D%5B%5CSigma%5Cfrac%7BQ%7D%7Br%7D%5D)
for single charge, E = 3.0 V = ![\frac{1}{4\pi \epsilon_o}[\frac{Q}{r}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%5Cpi%20%5Cepsilon_o%7D%5B%5Cfrac%7BQ%7D%7Br%7D%5D)
->eq(1)
And for 4 charges:
![E=\frac{1}{4\pi \epsilon_o}[4\frac{Q}{r}]](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B1%7D%7B4%5Cpi%20%5Cepsilon_o%7D%5B4%5Cfrac%7BQ%7D%7Br%7D%5D)
-eq(2)
from eq(1) and (2) we have
E = 4 × 3.0 V = 12 V
Answer:
His fight or flight is being activated making the adrenaline go through him making him alert and ready for what's coming at him. Depending on what happens next Fight or Flight will take place. If the body feels in danger he will flee and if the body thinks it's not as big of a threat he can fight it off.
