A beam of light of fixed intensity is directed at a linear polarizing filter whose transmission axis is at an angle of 45∘ above the positive ‑axis. For which incident polarization does the filter reduce light intensity the most?

(A) The incident light is unpolarized.

(B) The incident light is polarized parallel to the ‑axis.

(c) The incident light is polarized at an angle of 45∘ below the positive ‑axis.

b.a device that inputs heat into a cool object

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

i think the answer would be reserve.
