Its alos why ammonia is great fro cleaning greasy stoves. Hope I could be of help! :)
Answer:
![V =-7221.43 \ V](https://tex.z-dn.net/?f=V%20%3D-7221.43%20%5C%20V)
Explanation:
<u>The Electric Potential</u>
The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.
To calculate the electric potential of a point charge Q at a distance r, we use the formula:
![\displaystyle V=\frac{kQ}{r}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7BkQ%7D%7Br%7D)
Where
![k=9\cdot 10^9\ N.m^2/c^2](https://tex.z-dn.net/?f=k%3D9%5Ccdot%2010%5E9%5C%20N.m%5E2%2Fc%5E2)
We are given the following data:
![Q=-3.37\cdot 10^{-6}\ c](https://tex.z-dn.net/?f=Q%3D-3.37%5Ccdot%2010%5E%7B-6%7D%5C%20c)
r = 4.20 m
Calculating:
![\displaystyle V=\frac{9\cdot 10^9*(-3.37\cdot 10^{-6})}{4.2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7B9%5Ccdot%2010%5E9%2A%28-3.37%5Ccdot%2010%5E%7B-6%7D%29%7D%7B4.2%7D)
![\mathbf{V =-7221.43 \ V}](https://tex.z-dn.net/?f=%5Cmathbf%7BV%20%3D-7221.43%20%5C%20V%7D)
KE = 1/2mv²
= 1/2(100)(4.0²)
KE = 800 J
hope this helps :)
Answer:
25 percent
Explanation:
The missing corner would be ' TT '
homo recessive would be the 'tt square
one out of four = 25 percent
