Answer:
option D= 50°
Explanation:
When sunlight passes through the first polarizer, the intensity reduces to its half
that is
.........(1)
let the angle between the polarizers be θ
then we know that the intensity of light after passing through second polarizer is
![I_2=I_1 cos\theta](https://tex.z-dn.net/?f=I_2%3DI_1%20cos%5Ctheta)
⇒
............(2) from (1)
also given that
..............(3)
equating 2 and 3 we get
![0.2I_o=0.5I_ocos^2\theta](https://tex.z-dn.net/?f=0.2I_o%3D0.5I_ocos%5E2%5Ctheta)
on solving the above equation we get
θ= 50.75°≅50°
hence the angle between polarizers is 50°
option D is correct
I don't see any answers, but I do know that machines help for example: make chocolate bars. people do not have to cut the bars or another example: salt or season chips. or washing laundry. or electric cutters help so we do not have to do it by hand or with a knife.
Does this Help?
Drag Force = bv^2 = ma; a = g = 9.81 m/s^2
b = mg/v^2 = (0.0023×9.81)/(9.4^2)
b = 0.000255
