A beam of unpolarized light with a power of 1.0 mW passes through two ideal linear polarizers in series. An ideal polarizerabsor

bs100% of the light perpendicular to itspolarization axis, and none of the light parallel to itspolarization axis. What should the angle between the polarization axes of the two polarizers be if you want the power emerging from the second polarize?

Answer:

the axes of the two polarizers are aligned, the angle between this axis must be zero

Explanation:

Polarizers are anisotropic systems where absorption is selective in each axis, in this case they indicate that on an axis they let 100% pass and perpendicular to this axis no light passes.

  The first polarizer defines a direction of light that of its axis, it is said that the light is polarized, when this light reaches the second polarized, so that it can pass the axis must be in the direction of the polarized beam.

In summary, the axes of the two polarizers are aligned, the angle between this axis must be zero

Does the rankine degree represent a larger or smaller temperature unit than the kelvin degree
zvonat [6]
The best and most correct answer among the choices provided by the question is the first choice, larger.

Rankine is Fahrenheit + 460 , while Kelvin is Celsius + 273. We all know that Fahrenheit has larger number compared to kelvin , thus rankine is much larger.
Hope my answer would be a great help for you.    If you have more questions feel free to ask here at Brainly.

The redshift of a star means that _____.
Gelneren [198K]
The correct answer is D. the star is getting farther away.

When the light has red-shifted, it shows that everything is moving away from a certain point. This is known as the Doppler effect and proves the Big Bang (which would be the center point that everything is moving away from). Just as a 'for your information', blue shift is when the star is moving towards us.

Hope I helped :)

Two streams merge to form a river. One stream has a width of 8.9 m, depth of 3.8 m, and current speed of 2.3 m/s. The other stre
SpyIntel [72]
<h2>Depth of river is 4.48 m</h2>

Explanation:

Discharge = Area x Velocity

Discharge of river = Discharge of stream 1 + Discharge of stream 2

A_rv_r=A_1v_1+A_2v_2

Area of stream 1 = w₁ x d₁ = 8.9 x 3.8 = 33.82 m²

Area of stream 2 = w₂ x d₂ = 6.5 x 3.9 = 25.35 m²

Velocity of stream 1 = 2.3 m/s

Velocity of stream 2 = 2.6 m/s

Velocity of river = 3 m/s

\texttt{Area of river = }w_r\times d_r=10.7\times d_r

Substituting

             A_rv_r=A_1v_1+A_2v_2\\\\10.7\times d_r\times 3=33.82\times 2.3+25.35\times 2.6\\\\d_r=4.48m

Depth of river = 4.48 m
