Answer:
2.345 would be the most precious because you have more numbers to work with and exact numbers
Answer:
D. It represents a very large, complex system.

I just did it on a p e x...
Answer:
![B= 7.5*10^{-15}T](https://tex.z-dn.net/?f=B%3D%207.5%2A10%5E%7B-15%7DT)
Explanation:
The magnetic field strenght on the z-axis at a distance d from the center is,
![B= \frac{\mu_0 Q\omega R^2}{8\pi d^3}](https://tex.z-dn.net/?f=B%3D%20%5Cfrac%7B%5Cmu_0%20Q%5Comega%20R%5E2%7D%7B8%5Cpi%20d%5E3%7D)
Our values are:
![R=20cm\\Q=30mc\\w=5rad/s\\d=2*10^3cm=20m](https://tex.z-dn.net/?f=R%3D20cm%5C%5CQ%3D30mc%5C%5Cw%3D5rad%2Fs%5C%5Cd%3D2%2A10%5E3cm%3D20m)
Replacing,
![B= \frac{(4\pi*10^{}-7)(30*10^{-3})(5)(0.2)^2}{8\pi(20)}](https://tex.z-dn.net/?f=B%3D%20%5Cfrac%7B%284%5Cpi%2A10%5E%7B%7D-7%29%2830%2A10%5E%7B-3%7D%29%285%29%280.2%29%5E2%7D%7B8%5Cpi%2820%29%7D)
![B= 7.5*10^{-15}T](https://tex.z-dn.net/?f=B%3D%207.5%2A10%5E%7B-15%7DT)
Answer:
Explanation:
The name of the article from which the quote "Physicists speak of the continuous dance of sub-atomic matter which goes on all the time. They have actually used the words dance of creation and destruction or energy dance." was taken from is Carl Sagan Fritjof Capra on The dance that reveals the mysteries of the universe-Part ll
If you have a string that is fixed on both ends the amplitude of the oscillation must be zero at the beginning and the end of the string. Take a look at the pictures I have attached. It is clear that our fundamental harmonic will have the wavelength of:
![\lambda_1=\frac{L}{2}](https://tex.z-dn.net/?f=%5Clambda_1%3D%5Cfrac%7BL%7D%7B2%7D)
All the higher harmonics are just multiples of the fundamental:
![\lambda_n=n\lambda_1\\ \lambda_n=n\frac{L}{2}](https://tex.z-dn.net/?f=%5Clambda_n%3Dn%5Clambda_1%5C%5C%20%5Clambda_n%3Dn%5Cfrac%7BL%7D%7B2%7D%20)
Three longest wavelengths are:
