Parallel-plate capacitor has there fore formula is
<span>C=(<span>ϵ0</span>A)/d
putting values</span>C=(8.85*10^-12*pi*.05^2)/.00063
=1.1*10^-10F
then Q=CV=1.1*10^-10*1000=1.1*10^-7C
as
<span>η=Q/A</span><span>therefore
(1.1*10^-7)/(pi*.05^2)
=1.4*10^-5C/m^ our answer
hope this helps</span>
Answer:
Here is the solution hope it helps:)
There are two main points that should be emphasized about the different types of electromagnetic radiation. The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy
hope this helps you!✌
Answer: The angle of incidence at which the light will fully be polarized is 60°
Explanation:
To find out the angle of incidence θB for which reflected light is fully polarized we use the equation
n1 sinθB = n2sin(90°− θB) = n 2cosθB
Since n1 is the index of refraction for medium 1 and n2 is the medium of refraction for medium 2 we then solve the equation to get
θB = tan −1 (n2/n1)
= tan −1 (2.22/1.28)=60.0°
