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:
8 m
Explanation:
Vertical component of the speed of the boat = 3.0 m/s
horizontal component of the boat = 4 m/s
the rowboat traveled the length of the river which = 6.0 m
time taken to travel across the 6 m wide river = 6 m / 3 m/s = 2 s
the distance far downstream of the starting point = horizontal speed × time = 4 m/s × 2 = 8 m
Answer:
25.2563 m/s
Explanation
This is the equation needed
So Just plug in!
