Let us situate this on the x axis, and let our uniform line of charge be positioned on the interval <span>(−L,0]</span> for some large number L. The voltage V as a function of x on the interval <span>(0,∞)</span> is given by integrating the contributions from each bit of charge. Let the charge density be λ. Thus, for an infinitesimal length element <span>d<span>x′</span></span>, we have <span>λ=<span><span>dq</span><span>d<span>x′</span></span></span></span>.<span>V(x)=<span>1/<span>4π<span>ϵ0</span></span></span><span>∫line</span><span><span>dq/</span>r</span>=<span>λ/<span>4π<span>ϵ0</span></span></span><span>∫<span>−L</span>0</span><span><span>d<span>x/</span></span><span>x−<span>x′</span></span></span>=<span>λ/<span>4π<span>ϵ0</span></span></span><span>(ln|x+L|−ln|x|)</span></span>
Answer:
Hydroelectricity is a renewable energy source.
Hydroelectricity increases the stability and reliability of electricity system
Hydroelectricity helps fight climate changes.
Explanation:
If we use hydroelectricity our country would be in good climate and not a bad one. And the best facts it is renewable.
Answer:
the air within our bodies (in our lungs and stomachs, for example) is exerting the same pressure outwards so there's no pressure difference and no need for us to exert any effort.
Explanation:
-happiness
Explanation:
- Happiness is a result of desires.
- People are known to feel happy when some of their most important desires are fulfilled.
- If desire is not important, people feel only greater or less satisfaction. But at one level, desires and happiness are excluded because when some desires are fulfilled they are extinguished, and only the feeling of happiness slowly fades.
- Happiness should not be waited passively, it should not be expected that it will come from the outside through some happy event or that other people will make us happy through great love.

<h2>
Answer: Its pressure is also increased</h2>
Explanation:
The expression for an Ideal Gas is:
Where:
is the pressure of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
As we can see, <u>there is a direct proportional relation between the temperature and the pressure</u>, which means that if the temperature increases the pressure of the gas increases as well.
