Answer:
![50.91 \mu C](https://tex.z-dn.net/?f=50.91%20%5Cmu%20C)
Explanation:
The magnitude of the net force exerted on q is known, we have the values and positions for
and q. So, making use of coulomb's law, we can calculate the magnitude of the force exerted by
on q. Then we can know the magnitude of the force exerted by
about q, finally this will allow us to know the magnitude of ![q_{2}](https://tex.z-dn.net/?f=q_%7B2%7D)
exerts a force on q in +y direction, and
exerts a force on q in -y direction.
![F_{1}=\frac{kq_{1} q }{d^2}\\F_{1}=\frac{(8.99*10^9)(25*10^{-6}C)(8.4*10^{-6}C)}{(0.18m)^2}=58.26 N\\](https://tex.z-dn.net/?f=F_%7B1%7D%3D%5Cfrac%7Bkq_%7B1%7D%20q%20%7D%7Bd%5E2%7D%5C%5CF_%7B1%7D%3D%5Cfrac%7B%288.99%2A10%5E9%29%2825%2A10%5E%7B-6%7DC%29%288.4%2A10%5E%7B-6%7DC%29%7D%7B%280.18m%29%5E2%7D%3D58.26%20N%5C%5C)
The net force on q is:
![F_{T}=F_{1} - F_{2}\\25N=58.26N-F_{2}\\F_{2}=58.26N-25N=33.26N\\\mid F_{2} \mid=\frac{kq_{2}q}{d^2}](https://tex.z-dn.net/?f=F_%7BT%7D%3DF_%7B1%7D%20-%20F_%7B2%7D%5C%5C25N%3D58.26N-F_%7B2%7D%5C%5CF_%7B2%7D%3D58.26N-25N%3D33.26N%5C%5C%5Cmid%20F_%7B2%7D%20%5Cmid%3D%5Cfrac%7Bkq_%7B2%7Dq%7D%7Bd%5E2%7D)
Rewriting for
:
![q_{2}=\frac{F_{2}d^2}{kq}\\q_{2}=\frac{33.26N(0.34m)^2}{8.99*10^9\frac{Nm^2}{C^2}(8.4*10^{-6}C)}=50.91*10^{-6}C=50.91 \mu C](https://tex.z-dn.net/?f=q_%7B2%7D%3D%5Cfrac%7BF_%7B2%7Dd%5E2%7D%7Bkq%7D%5C%5Cq_%7B2%7D%3D%5Cfrac%7B33.26N%280.34m%29%5E2%7D%7B8.99%2A10%5E9%5Cfrac%7BNm%5E2%7D%7BC%5E2%7D%288.4%2A10%5E%7B-6%7DC%29%7D%3D50.91%2A10%5E%7B-6%7DC%3D50.91%20%5Cmu%20C)
The melting of polar ice is one effect of the greenhouse effect, or also global warming.
The greenhouse effect, as defined by Merriam-Webster, is "the <span>warming of the surface and lower atmosphere of a planet (as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases".
In short, "</span>the warming of the surface and lower atmosphere of a planet".
Answer:
The average speed of the earth in its orbit is ![29.86km/s](https://tex.z-dn.net/?f=29.86km%2Fs)
Explanation:
The average distance between the Earth and the Sun is
.
The average speed of the earth in its orbit can be found by the next equation :
(1)
Where r is the radius and T is the period.
In this case, the orbit of the Earth can be considered as a circle
(
) instead of an ellipse.
It takes 1 year to the Earth to make one revolution around the Sun. Therefore, its period will be 365.25 days.
Notice that to express the period in terms of seconds, the following is needed:
⇒ ![31557600s](https://tex.z-dn.net/?f=31557600s)
Then, equation 1 can be used:
![v = \frac{2 \pi (1.50x10^{8}km)}{31557600s}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B2%20%5Cpi%20%281.50x10%5E%7B8%7Dkm%29%7D%7B31557600s%7D)
![v = 29.86km/s](https://tex.z-dn.net/?f=v%20%3D%2029.86km%2Fs)
Answer:
800 mL
Explanation:
D*V=M
You pick out the numbers as well as what it is they represent from the word problem/explanation, then from there plug them in to the equations. Once you do that, you get your product and have the answer.
10*80= 800
