Early cameras were little more than a box with a pinhole on the side opposite the film. (a) what angular resolution would you expect from a pinhole with a 0.36-mm diameter? (assume light with a wavelength of 520 nm.)
(b) what is the greatest distance from the camera at which two point objects 29 cm apart can be resolved?

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

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
