Answer:
850.8480103 feet
Explanation:
First you take the diameter and find the circumference, which is (2)(pi)(r) plug in your r which is 26/2= 13 so 2(13)(pi) and multiply taht by 125 after that take your answer and divide by 12which is 850.8480103
Answer:
the sun gives off light while at the same time gives off heat. the shoe box cooker takes that heat and light and reflects it around the shoe box. then the heat settles down into whatever is in the shoe box. the heat after being reflected around the shoe box is magnified by the foil wrapped in the box thus allowing the food or drink to be heated. the foil is a conductor of heat because it is metal .

Answer:
![2.9\times 10^{-6}](https://tex.z-dn.net/?f=2.9%5Ctimes%2010%5E%7B-6%7D)
Explanation:
= Energy for defect formation = 1.86 eV
T = Temperature = ![573^{\circ}\text{C}=573+273.15=846.15\ \text{K}](https://tex.z-dn.net/?f=573%5E%7B%5Ccirc%7D%5Ctext%7BC%7D%3D573%2B273.15%3D846.15%5C%20%5Ctext%7BK%7D)
k = Boltzmann constant = ![8.62\times 10^{-5}\ \text{eV/K}](https://tex.z-dn.net/?f=8.62%5Ctimes%2010%5E%7B-5%7D%5C%20%5Ctext%7BeV%2FK%7D)
The fraction of lattice sites that are Schottky defects is given by
![\dfrac{N_s}{N}=e^{-\dfrac{Q_s}{2kt}}\\\Rightarrow \dfrac{N_s}{N}=e^{-\dfrac{1.86}{2\times 8.62\times 10^{-5}\times 846.15}}\\\Rightarrow \dfrac{N_s}{N}=2.9\times 10^{-6}](https://tex.z-dn.net/?f=%5Cdfrac%7BN_s%7D%7BN%7D%3De%5E%7B-%5Cdfrac%7BQ_s%7D%7B2kt%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BN_s%7D%7BN%7D%3De%5E%7B-%5Cdfrac%7B1.86%7D%7B2%5Ctimes%208.62%5Ctimes%2010%5E%7B-5%7D%5Ctimes%20846.15%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BN_s%7D%7BN%7D%3D2.9%5Ctimes%2010%5E%7B-6%7D)
