Overcourse this is true.

Air pollution causes distortions to the air organisms breathe.
The type of pollution that is caused by particles in the air is called Particulates and it is a type of air pollution.These are highly deadly for all living beings. The minute solid or liquid particles that are present in the air or atmosphere can cause a great amount of damage to the lungs of humans. WHO or World Health Organization has designated Particulates as Group 1 carcinogen. The particulates are considered as the deadliest form of air pollution as it can mix with blood unhindered and create death, heart attack or heart ailment and even go as far as creating DNA mutation.

Explanation:

Function of distance w.r.t time :

$x(t) = \: y = \sqrt{2t}$

Differentiate w.r.t time to get velocity :

$\frac{dy}{dt} = v = \frac{1}{ \sqrt{2t} }$

Differentiate w.r.t time to get Acceleration :

$\frac{d^2y}{dx^2} = a \: = - \frac{1}{2t \sqrt{2t} }$

A 100 Ω resistor is connected in series with a 47 µF capacitor and a source whose maximum voltage is 5 V, operating at 100.0 Hz.

Pani-rosa [81]

Answer:

$X_c=-33.86275385\Omega$

$|Z|=105.5778675\Omega$

$I=0.04735841062A$

$\phi=20.78612878\°$

Explanation:

The electrical reactance is defined as:

$X_c=-\frac{1}{2\pi fC}$

Where:

$f=Frequency\\C=Capacitance$

So, replacing the data provided by the problem:

$X_c=\frac{1}{2\pi *100*(47*10^{-6} )} =-33.86275385\Omega$

Now, the impedance can be calculated as:

$Z=R+jX_c$

Where:

$R=Resistance\\X_c= Capacitive\hspace{3}reactance$

Replacing the data:

$Z=100-j33.86275385$

In order to find the magnitude of the impedance we can use the next equation:

$|Z|=\sqrt{(R^2)+(X_c^2)}=\sqrt{(100)^2+(-33.86275385)^2} =105.5778675\Omega$

We can use Ohm's law to find the current:

$V=I*Z\\I=\frac{V}{Z}$

Therefore the current is:

$I=\frac{5}{100-j33.86275385}=0.04485638113+0.01518960593j$

And its magnitude is:

$|I|=\sqrt{(0.04485638113)^2+(0.01518960593)^2} =0.04735841062\Omega$

Finally the phase angle of the current is given by:

$\phi=arctan(\frac{0.01518960593}{0.04485638113})=20.78612878\°$

A Panuto: Mahalagang kilalanin ang sarili at alamin ang sanling kahinaan at kakayahan bago gumawa

Kaylis [27]

Answer:

Ako ay isang simpleng tao hindi mapilit sa'king kagustuhan,marespeto sa kapwa,nagsasabi ng 'po' at 'opo' lalong lalo na Kung mas nakakatanda pa sa'kin yung kausap ko.Hindi porke mahirap ako ay marami ng mang-aapi o nambu_bully sa'kin ,,,pero wala akong napansing ganun kasi kapag marespeto ka ay bumabalik at bumabalik parin yun sayo yung kabutihan na ipanapakita mo sa ibang tao.Hindi ako isang tao na kung anuman ang nakikita ko sa nakakarami ay gagayahin ko,bibilhin ko,o magdedemand lang SA MGA magulang ko para mabili yung aking kagustuhan.Isang taong marunong makuntento sa anumang meron,isang taong may respeto sa kapwa,isang taong mabuti ang loob wag nyu lng unahan,isang taong hindi magastos sa mga walang kwentang bagay,masimple at palaban sa anumang hapon na hinaharap.
