Unpolarized light is passed through three successive polaroid filters, each with its transmission axis at 32. 8° to the precedin
Oliga [24]

The percentage of light gets through three successive polarized filters is 24.9 %

From the question,

Given that,

Angle of transmission axis = 32.8°

The intensity of light emerging from the first polarizer is determined by the equation

I₁ = I₀ / 2

where I₀ ⇒ intensity of unpolarized light

The light emerging from the second polarizer can be mathematically represented by,

I₂ = I₁ x cos²θ

Substituting the values,

I₂ =( I₀/2) x cos²θ

  = (I₀/2) x cos² (32.8 )

  = (I₀/2) x 0.706

  = (0.706 / 2 ) x I₀

The light emerging from the third polarizer is represented as,

I₃ = I₂ x cos²θ

Substituting the values in the above equation,

I₃ = ( 0.706 / 2 ) I₀ x cos² (32.8)

  = (0.706 / 2 ) I₀ x 0.706

  = 0.249 I₀

The percentage of intensity of light  that gwts through with respect to the intensity of unpolarized light is given by the equation,

(I₃ / I₀) x 100

Substituting the values

[(0.249 x I₀) / I₀ ] x 100 = 24.9 %

Hence the percentage of light gets through is 24.9%

A 30 gram piece of iron is heated to 100°C and then dropped into
Hitman42 [59]

Q= calories

m = mass

c = specific heat

∆t = temperature difference

Also, Qin = Qout

(as in the amount of energy lost by the iron equals the energy gained by water. the water) so the calories lost is as stated in pict.

In two or more complete sentences, explain how you can prove that the number of degrees that the Moon rotates around the Earth e
PolarNik [594]

Answer:

Follows are the explanation to this question:

Explanation:

In this solution, it is defined that there are two principal motions for the moon, which are its revolution as well as rotation. In such a movement called revolution, its Moon is relocating around the Earth, in which the approximate movement of the moon from around earth has an average movement of about 13.2° per day, or 92 degrees every week, that's once in 27.3 days.

Ben climbs a tree to retrieve a lost football. If he does 2,400 J of work to climb 8 m, how much force is he using?
krok68 [10]
Work = Force * distance.
d = 8 m
W = 2400 J
F = ???

2400 = 8 * F
F = 2400/8
F = 300 N
