The answer would be 27,000 Joules because (1/2) m v^2 =30*900 which equals 27,000 J
Explanation:
i hope this helps, its not the same person but its the same equation.
When you say full valence shell, are you talking about a valence electron shell?
I am learning about atoms and i know a little bit
Answer:
Potential difference = 245 V
Explanation:
First, we have to find velocity at which ionized molecules are accelerated into a magnetic field. Here, magnetic force acts as a centripetal force due to circular path of molecules towards detector slot.
- B= 0.25 T,d= 12 cm
- mass = (12+16+16)×1.67×10-27kg
Now, the magnetic force to the centripetal force equates as:
qvB =
= ![\frac{mv2}{d/2}](https://tex.z-dn.net/?f=%5Cfrac%7Bmv2%7D%7Bd%2F2%7D)
For Velocity (v) :
v = ![\frac{qBd}{2m}](https://tex.z-dn.net/?f=%5Cfrac%7BqBd%7D%7B2m%7D)
According to law of conservation of energy, we know that the initial potential energy of the molecules is converted into kinetic energy as they enter into the magnetic field. So,
![qV=\frac{1}{2}mv2](https://tex.z-dn.net/?f=qV%3D%5Cfrac%7B1%7D%7B2%7Dmv2)
Substitute the value of v in above equation:
qV =
m ![\frac{q2B2d2}{4m2}](https://tex.z-dn.net/?f=%5Cfrac%7Bq2B2d2%7D%7B4m2%7D)
V = ![\frac{qB2d2}{8m}](https://tex.z-dn.net/?f=%5Cfrac%7BqB2d2%7D%7B8m%7D)
V= 245 V
