How does the volume of an adult’s lungs, about 5.0 l at sea level (1.0 atm), change when he dives to a depth at which water pressure is 2.3 atm? assume that temperature is constant.
a)1.0 l
b)1.5 l
c)2.2 l
d)no change

b.

hope this : )

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

compass can be used day and night, cloudy or sunny
