An electric generator is when a magnet is rotated through a coil of wire to produce an electric current.
Answer:
The amount of carbon dioxide is little in deionized water.
Explanation:
Deionized water is a water with little or no impurities. Impurities are in waters are not able to boil below or above the boiling point of water,and in this case are been retained in the original container.
Evaporation (or another word to use is water vapor.)
I believe an Atom is a very powerful source, the basic unit of a chemical element. An atom is a source of nuclear energy.
But a molecule on the other hand isn't so different.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
I hope that helps, have a fantastic day!
Answer:
![Potential\ Energy=Work \ Done=2.301*10^{-18} J](https://tex.z-dn.net/?f=Potential%5C%20Energy%3DWork%20%5C%20Done%3D2.301%2A10%5E%7B-18%7D%20J)
Work done to bring three electrons from a great distance apart to 3.0×10−10 m from one another (at the corners of an equilateral triangle) is ![2.301*10^{-18} Joules](https://tex.z-dn.net/?f=2.301%2A10%5E%7B-18%7D%20Joules)
Explanation:
The potential energy is given by:
U=Q*V
where:
Q is the charge
V is the potential difference
Potential Difference=V=![\frac{kq}{r}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq%7D%7Br%7D)
So,
![Potential\ Energy=\frac{Qkq}{r} \\Q=q\\Potential\ Energy=\frac{kq^2}{r}](https://tex.z-dn.net/?f=Potential%5C%20Energy%3D%5Cfrac%7BQkq%7D%7Br%7D%20%5C%5CQ%3Dq%5C%5CPotential%5C%20Energy%3D%5Cfrac%7Bkq%5E2%7D%7Br%7D)
Where:
k is Coulomb Constant=![8.99*10^9 Nm^2/C^2](https://tex.z-dn.net/?f=8.99%2A10%5E9%20Nm%5E2%2FC%5E2)
q is the charge on electron=![-1.6*10^-19 C](https://tex.z-dn.net/?f=-1.6%2A10%5E-19%20C)
r is the distance=![3.0*10^{-10}m](https://tex.z-dn.net/?f=3.0%2A10%5E%7B-10%7Dm)
For 3 Electrons Potential Energy or work Done is:
![Potential\ Energy=3*\frac{kq^2}{r}](https://tex.z-dn.net/?f=Potential%5C%20Energy%3D3%2A%5Cfrac%7Bkq%5E2%7D%7Br%7D)
![Potential\ Energy=3*\frac{(8.99*10^9)(-1.6*10^{-19})^2}{3*10^{-10}}\\Potential\ Energy=2.301*10^{-18} J](https://tex.z-dn.net/?f=Potential%5C%20Energy%3D3%2A%5Cfrac%7B%288.99%2A10%5E9%29%28-1.6%2A10%5E%7B-19%7D%29%5E2%7D%7B3%2A10%5E%7B-10%7D%7D%5C%5CPotential%5C%20Energy%3D2.301%2A10%5E%7B-18%7D%20J)
Work done to bring three electrons from a great distance apart to 3.0×10−10 m from one another (at the corners of an equilateral triangle) is ![2.301*10^{-18} Joules](https://tex.z-dn.net/?f=2.301%2A10%5E%7B-18%7D%20Joules)
