Consider 3 polarizers. Polarizer 1 has a vertical transmission axis and polarizer 3 has a horizontal transmission axis. Taken to
kirill [66]

Answer:

Option D.) 0.09 I₀

Explanation:

The intensity, I, of a polarized light after passing through a polarizing filter is given by I = I_{0} cos^{2}  \theta

I_{0} = Original Intensity

\theta = Angle between the direction of polarization and the axis of filter

After passing through the first polarizer, the initial intensity, I_{o} is halved, i.e I_{1} = \frac{I_{0} }{2}

After passing through the second polarizer, the angle of polarization, θ = 30⁰

I_{2} = I_{1} cos^{2} \theta

I_{2} = \frac{I_{0} }{2} cos^{2} 30\\I_{2} =\frac{3}{8} I_{0} \\I_{2} = 0.375 I_{0}

After passing through the third polarizer, the angle of polarization, θ = 90⁰-30⁰ = 60⁰

I_{3} = I_{2} cos^{2} \theta

I_{3} = 0.375I_{0} cos^{2} 60

I_{2} =0.09 I_{0}

A hydraulic lift consists of two pistons that connect to each other by an incompressible fluid. If one piston has an area of 0.1

You have:
 
 A1= 0.15 m²
 A2=6.0 m²
 F1=130.0 N
 
 To solve this problem you must use the pressure formula, as below:
 
 P1=P2
 F1/A1=F2/A2
 
 Then, you have:
 
 m2=A2xF1/A1xg
 
 g=9.81 m/s² (This is the acceleration of gravity)
 
 When you substitute the values in m2=A2xF1/A1xg, you obtain:
 
 m2=(0.60 m² x 130.0 N)/(0.15 m² x 9.81 m/s²)
 
 The answer is:
 
 m2=530 Kg
