Answer:
The intensity of the light that passes through a polarizer is 0.55I₀.
Explanation:
The intensity of the light that passes through a polarizer can be found using Malus's law:

<u>Where</u>:
I: is the intensity of the light that passes through a polarizer
I₀: is the initial intensity
θ: is the angle between the light's initial polarization direction and the axis of the polarizer = 42°

Therefore, the intensity of the light that passes through a polarizer is 0.55I₀.

Answer:
114.86%
Explanation:
In both cases, there is a vertical force equal to the sprinter's weight:
Fy = mg
When running in a circle, there is an additional centripetal force:
Fx = mv²/r
The net force is found with Pythagorean theorem:
F² = Fx² + Fy²
F² = (mv²/r)² + (mg)²
F² = m² ((v²/r)² + g²)
F = m √((v²/r)² + g²)
Compared to just the vertical force:
F / Fy
m √((v²/r)² + g²) / mg
√((v²/r)² + g²) / g
Given v = 12 m/s, r = 26 m, and g = 9.8 m/s²:
√((12²/26)² + 9.8²) / 9.8
1.1486
The force is about 114.86% greater (round as needed).
