Answer:
45°
Explanation:
I = Polarized light after 3 filter = 0.5 W/m²
= Initial light intensity = 4 W/m²
The intensity of polarized light is given by
Hence, the angle relative to the vertical was the light initially polarized is 45°

Answer:
v = 2 m/s.
Explanation:
From the given graph, it is clear that the position is bee is 8 m between 4 s to 6 s. It would mean that its displacement is equal to 0 because final position is equal to initial position.
Between 6 s to 8 s, its velocity is decreasing and it is calculated using slope. The slope of position time graph gives velocity of an object.
So, the velocity of the bee between 4 s to 8 s is 2 m/s.
