Answer:
![Ep=-2.3*10^{-19}J](https://tex.z-dn.net/?f=Ep%3D-2.3%2A10%5E%7B-19%7DJ)
Explanation:
The change in potential energy can be expressed as:
![Ep=K.\frac{q1.q2}{r}](https://tex.z-dn.net/?f=Ep%3DK.%5Cfrac%7Bq1.q2%7D%7Br%7D)
where K is a constant with a value of
, q1 and q2 are the charges of the proton and the electron and r is the distance between them.
The charge for the proton is
and the charge for the electron is
.
Converting r=1.0nm to m:
![1.0nm*\frac{1*10^{-9}m}{1.0nm}=1*10^{-9}m](https://tex.z-dn.net/?f=1.0nm%2A%5Cfrac%7B1%2A10%5E%7B-9%7Dm%7D%7B1.0nm%7D%3D1%2A10%5E%7B-9%7Dm)
Replacing values:
![Ep=9*10^{9}\frac{N.m^{2}}{C^{2}}.\frac{(+1.6*10^{-19}C).(-1.6*10^{-19}C)}{1*10^{-9}m}](https://tex.z-dn.net/?f=Ep%3D9%2A10%5E%7B9%7D%5Cfrac%7BN.m%5E%7B2%7D%7D%7BC%5E%7B2%7D%7D.%5Cfrac%7B%28%2B1.6%2A10%5E%7B-19%7DC%29.%28-1.6%2A10%5E%7B-19%7DC%29%7D%7B1%2A10%5E%7B-9%7Dm%7D)
![Ep=-2.3*10^{-19}J](https://tex.z-dn.net/?f=Ep%3D-2.3%2A10%5E%7B-19%7DJ)
Answer:
Human-driven changes in arrive utilize and arrive cover such as deforestation, urbanization, and shifts in vegetation designs moreover change the climate, coming about in changes to the reflectivity of the Soil surface (albedo), emanations from burning timberlands, urban warm island impacts and changes within the normal water cycle.
Explanation:
A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.
