Amodern-day zeppelin holds 9,650 m3 of helium. compute its maximum payload at sea level. (assume the helium and air to be at 0°c and 1 atm.)

10809.93 kg

Explanation:

= Density of air = 1.292 kg/m³

= Density of air = 0.1718 kg/m³

V = Volume of Helium = 9650 m³

g = Acceleration due to gravity = 9.81 m/s²

Net force on the zeppelin is given by

The maximum payload will be

answer: i pick a

explanation:

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
