Its 1.0*10^-7M its considered a concentration because hydrogen ion is exactly equal to hydroxide ions produced by dissociation of water
Answer:
E = 5291.00 N/C
Explanation:
Expression for capacitance is
![C = \frac{\epsilon A}{d}](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%7B%5Cepsilon%20%20A%7D%7Bd%7D)
where
A is area of square plate
D = DISTANCE BETWEEN THE PLATE
![C = \frac{\epsilon\times(19\times 10^{-2})^2}{1.5\times 10^{-3}}](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%7B%5Cepsilon%5Ctimes%2819%5Ctimes%2010%5E%7B-2%7D%29%5E2%7D%7B1.5%5Ctimes%2010%5E%7B-3%7D%7D)
![C = 24.06 \epsilon](https://tex.z-dn.net/?f=C%20%3D%2024.06%20%5Cepsilon)
![C = 24.06\times 8.854\times 10^{-12} F](https://tex.z-dn.net/?f=C%20%3D%2024.06%5Ctimes%208.854%5Ctimes%2010%5E%7B-12%7D%20F)
![C =2.1\times 10^{-10} F](https://tex.z-dn.net/?f=C%20%3D2.1%5Ctimes%2010%5E%7B-10%7D%20F)
We know that capacitrnce and charge is related as
![V = \frac{Q}{C}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7BQ%7D%7BC%7D)
![= \frac{2\tiimes 10^{-9}}{2.\times 10^{-10}}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2%5Ctiimes%2010%5E%7B-9%7D%7D%7B2.%5Ctimes%2010%5E%7B-10%7D%7D)
v = 9.523 V
Electric field is given as
![E = \frac{V}{d}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7BV%7D%7Bd%7D)
= ![\frac{9.52}{1.8*10^{-3}}](https://tex.z-dn.net/?f=%5Cfrac%7B9.52%7D%7B1.8%2A10%5E%7B-3%7D%7D)
E = 5291.00 V/m
E = 5291.00 N/C
K = 1/2mv^2 of kinetic energy. The change in the object's kinetic energy is equal to the net work performed on it.
<h3>What causes the kinetic energy to change?</h3>
Equations. Mass and the square of the velocity are directly related to translational kinetic energy. The difference between the end and starting kinetic energies is known as change in kinetic energy.
<h3>In solar panels, is there kinetic energy?</h3>
employing semiconductor-cell-based panels. technique that uses solar thermal systems to store solar energy. This heat is used directly or transformed into concentrated solar power, or the sum of the potential energy and kinetic energy of an object or system, and electricity.
