Answer:
answer is A corresponding to 60 W
Explanation:
The polarization phenomenon is descriptor Malus's law
I = I₀ cos² θ
Where I and Io are the transmitted and incident intensities, respectively, θ is the angle between the direction of polarization of the light and the polarizer.
Unpolarized light strikes the first polarizer and half of it is transmitted, which has the polarization direction of the polarizer
I₁ = ½ I₀
I₁ = ½ 300
I₁ = 150 W
The transmission by the second polarizer (P2) is
I₂ = I₁ cos² θ
1
I₂ = 150 cos² 45
I₂ = 75 W
The transmission of the third polarizer (P3)
I₃ = I₂ cos² θ
2
I₃ = 75 cos² 30
I₃ = 56.25 W
This is the light transmitted by the 56 W system, the closest answer is A corresponding to 60 W

Answer: The box was moving with a velocity of 0.256m/s when it hit the spring
Explanation: Please see the attachments below
No, aluminum has a density near 2.7 g/cm^3
<span>7.8 g/cm^3 is near the density of iron (or in the case of a fork, steel).
this is it
