A vertically polarized beam of light of intensity 100 W/m2 passes through two ideal polarizers. The transmission axis of the fir
TEA [102]

To solve the problem it is necessary to apply the Malus Law. Malus's law indicates that the intensity of a linearly polarized beam of light, which passes through a perfect analyzer with a vertical optical axis is equivalent to:

I=I_0 cos^2\theta

Where,

I_ {0} indicates the intensity of the light before passing through the polarizer,

I is the resulting intensity, and

\theta indicates the angle between the axis of the analyzer and the polarization axis of the incident light.

Since we have two objects the law would be,

I=I_0cos^2\theta_1*cos^2(\theta_2-\theta_1)

Replacing the values,

I=100*cos^2(20)*cos^2(40-20)

I=100*cos^4(20)

I=77.91W/m^2

Therefore the intesity of the light after it has passes through both polarizers is 77.91W/m^2

What is your acceleration while sitting in your chair. the latitude of corvallis is 44.4˚.?
marta [7]
 <span>You can start with the equations you know 

a=v^2/r = (2pi*r/T)^2/r = 4pi^2r/T^2 

Radius of earth (R) = 6378.1 km 
Time in one day (T) = 86400 seconds 
Latitude = 44.4 degrees 

If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r. 

r=Rcos(44.4) 
r=6378.1cos(44.4) 
r= 4556.978198 km or 4556978 m 

Now you can plug this value into the acceleration equation from above... 

a= 1.8*10^8/7.47*10^9 
a= .0241 m/s^2 </span>
