This figure shows an all-sky map of the cosmic microwave background recorded by the wmap telescope. how long did this light travel through space before it reached the telescope?

Light from the sky travels to a large concave mirror, where it reflects onto a small flat mirror. The small mirror reflects the light, sending it to a magnifying lens. The lens is part of the eyepiece, where the magnified light reaches the viewer’s eye.

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

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
