In 1990, a pizza with a radius of 18.0 m was made in South Africa. Suppose you make an air-filled capacitor with parallel plates

Mazyrski [523]

Explanation:

We have,

Radius of pizza, r = 18 m

Potential difference, V = 575 V

Stored electrical potential energy, E = 3.31 J

The area if an air-filled capacitor with parallel plates is equal to that of the pizza. It means, $A=\pi r^2=\pi (18)^2=1017.87\ m^2$

The stored potential energy in a capacitor is given by :

$E=\dfrac{1}{2}CV^2$

C is capacitance

$C=\dfrac{2E}{V^2}\\\\C=\dfrac{2\times 3.31}{(575)^2}\\\\C=2\times 10^{-5}\ F$

The formula of the capacitance of a parallel plate capacitor is given by :

$C=\dfrac{\epsilon_o A}{d}$

d is plate separation of this capacitor

$d=\dfrac{\epsilon_o A}{C}\\\\d=\dfrac{8.85\times 10^{-12}\times 1017.87}{2\times 10^{-5}}\\\\d=4.5\times 10^{-4}\ m$

What electron configuration has the greatest stability?

posledela

An atom is in a stable form when its outer electron shell is full and electronic configurations having duplet structure means two valence electrons and octet structure means eight valence electrons has the greatest stability. Mostly atoms of elements have not stable configuration and to acheive stable configuration they react with other atoms to transfer, share or receive electrons.
