Answer:
they were in two places in flint and Birmingham and in Birmingham it is hot but flint of cold the Simi is they both have Sunday school for Joetta
Explanation:
use in your own words teachers know when your not trust me.
First of all, we can calculate the frequency of the photon, which is related to the wavelength by the following equation:
![f= \frac{c}{\lambda}](https://tex.z-dn.net/?f=f%3D%20%5Cfrac%7Bc%7D%7B%5Clambda%7D%20)
where c is the speed of light and
![\lambda=670.8 nm=670.8 \cdot 10^{-9} m](https://tex.z-dn.net/?f=%5Clambda%3D670.8%20nm%3D670.8%20%5Ccdot%2010%5E%7B-9%7D%20m)
is the photon wavelength. Substituting into the formula, we find the frequency
![f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{670.8 \cdot 10^{-9} m}=4.47 \cdot 10^{14} Hz](https://tex.z-dn.net/?f=f%3D%20%5Cfrac%7Bc%7D%7B%5Clambda%7D%3D%20%5Cfrac%7B3%20%5Ccdot%2010%5E8%20m%2Fs%7D%7B670.8%20%5Ccdot%2010%5E%7B-9%7D%20m%7D%3D4.47%20%5Ccdot%2010%5E%7B14%7D%20Hz%20%20)
Now we can find the energy of the photon with the following equation:
![E=hf](https://tex.z-dn.net/?f=E%3Dhf)
where h is the Planck constant. Substituting numbers, we find
Answer:
Coulomb, unit of electric charge in the metre- kilogram- second- ampere system, the basis of SI system of physics unit. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.
