Answer:
It takes the Moon 27.3 days to complete a single orbit around Earth.
Explanation:
No.
If they add together to get a vector of length zero they should make a triangle of loading.
The sides 1 m, 2 m and 4 m will not make a triangle since the sum of 1 and 2 is less than 4.
In the given figure a+b < c , so they make a triangle.
Here this condition is not satisfied.
C,d,or e you can use the process of elimination to decide...
Explanation:
(a) The Schrodinger's wave function represent the position of a particle at a particular instant of time. It is also known as the probability amplitude. It is also used to find the location of a particle.
(b) The width of a potential well, ![l=5\ A=5\times 10^{10}\ m](https://tex.z-dn.net/?f=l%3D5%5C%20A%3D5%5Ctimes%2010%5E%7B10%7D%5C%20m)
For first energy level, n = 1
Energy in infinite potential well is given by :
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(1)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%281%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.0120 Joules
For second energy level, n = 2
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(2)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%282%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.0483 Joules
For third energy level, n = 3
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(3)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%283%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.108 Joules
Hence, this is the required solution.
The different versions of an element have different isotopes, like Copper-63 and Carbon-65. The average of these two is not 64, because there are more Carbon-63 in the world than Carbon-65, 69.17% Copper-63 and 30.83% Copper-65, to be exact. By multiplying the atomic mass per unit of each one times their respective abundance in the world turned into a decimal, and adding these two products together, you het the atomic mass overall, which is 63.55
