Unpolarized light of intensity I=10 falls on two successive polarizer wheels with the angle between the polarizer wheels e-60°.
yan [13]

Answer:

I=\frac{10}{4}

Explanation:

A polarizer changes the orientation of the oscillations of a light wave.

I₀ = Intensity of unpolarized light = 10

θ = Angle given to the polarizer = 60°

Intensity of light

I = I₀cos²θ

⇒I = 10cos²60

\\\Rightarrow I=10\times \frac{1}{2}\times \frac{1}{2}\\\Rightarrow I=\frac{10}{4}

So, the after passing through the second polarizer is \mathbf{\frac{10}{4}}

Hot air balloon A is rising upward a rate of 5.0 m/s. A passenger aboard balloon A observes balloon B rising upward at a relativ
AnnZ [28]
Velocity B (relative to the A) = Velocity B (relative to the ground) - Velocity A (relative to the ground)

Velocity B (relative to the ground) = Velocity B (relative to the A) + Velocity A (relative to the ground)

Velocity B (relative to the ground) = 7.5 + 5 = 12 m/s

Since both go up in the same direction, we should use the minus sign for relative velocity.
