e = Charge of electron = ![1.6\times 10^{-19}\ C](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E%7B-19%7D%5C%20C)
k = Coulomb constant = ![8.99\times 10^{9}\ Nm^2/C^2](https://tex.z-dn.net/?f=8.99%5Ctimes%2010%5E%7B9%7D%5C%20Nm%5E2%2FC%5E2)
Z = Atomic number of water = 18
M = Molar mass of water = 0.018 kg/mol
m = Mass of person
The charge is given by
![q=imbalance\times n\times e](https://tex.z-dn.net/?f=q%3Dimbalance%5Ctimes%20n%5Ctimes%20e)
Total number of protons and electrons in each sphere
![n=\dfrac{mN_AZe}{M}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7BmN_AZe%7D%7BM%7D)
![q=imbalance\times \dfrac{mN_AZe}{M}](https://tex.z-dn.net/?f=q%3Dimbalance%5Ctimes%20%5Cdfrac%7BmN_AZe%7D%7BM%7D)
![q_1=0.0004\times \dfrac{96\times 6.022\times 10^{23}\times 18\times 1.6\times 10^{-19}}{0.018}\\\Rightarrow q_1=3699916.8\ C](https://tex.z-dn.net/?f=q_1%3D0.0004%5Ctimes%20%5Cdfrac%7B96%5Ctimes%206.022%5Ctimes%2010%5E%7B23%7D%5Ctimes%2018%5Ctimes%201.6%5Ctimes%2010%5E%7B-19%7D%7D%7B0.018%7D%5C%5C%5CRightarrow%20q_1%3D3699916.8%5C%20C)
![q_2=0.0004\times \dfrac{48\times 6.022\times 10^{23}\times 18\times 1.6\times 10^{-19}}{0.018}\\\Rightarrow q_1=1849958.4\ C](https://tex.z-dn.net/?f=q_2%3D0.0004%5Ctimes%20%5Cdfrac%7B48%5Ctimes%206.022%5Ctimes%2010%5E%7B23%7D%5Ctimes%2018%5Ctimes%201.6%5Ctimes%2010%5E%7B-19%7D%7D%7B0.018%7D%5C%5C%5CRightarrow%20q_1%3D1849958.4%5C%20C)
Electrical force is given by
![F=\dfrac{kq_1q_2}{r^2}\\\Rightarrow F=\dfrac{8.99\times 10^{9}\times 3699916.8\times 1849958.4}{30^2}\\\Rightarrow F=6.8370869499\times 10^{20}\ N](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7Bkq_1q_2%7D%7Br%5E2%7D%5C%5C%5CRightarrow%20F%3D%5Cdfrac%7B8.99%5Ctimes%2010%5E%7B9%7D%5Ctimes%203699916.8%5Ctimes%201849958.4%7D%7B30%5E2%7D%5C%5C%5CRightarrow%20F%3D6.8370869499%5Ctimes%2010%5E%7B20%7D%5C%20N)
The electrostatic force of attraction between them is ![6.8370869499\times 10^{20}\ N](https://tex.z-dn.net/?f=6.8370869499%5Ctimes%2010%5E%7B20%7D%5C%20N)
Answer:
The answer is the kinetic energy of sled B after it crash is 6439j.
Answer:
Atoms have protons and neutrons in the center, making the nucleus, while the electrons orbit the nucleus. The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different. What makes atoms of different elements different?

Explanation:
<span>To begin, the formula for finding frequency when wavelength is known is "f = c / w" when c is the constant velocity (3 * 10^8 m/s). To convert the wavelength into a common form (m/s), it will have to be multiplied by 10^-2. This leaves the equation as "f = 3.0 * 10^8 / (2.4 * 10^-5 * 10^-2), or 2.4 * 10^-7. This gives 1.25 * 10^15 m/s as the frequency.</span>
