Consider an ideal gas being heated at constant volume, and let cv be the gas's molar heat capacity at constant volume. if the gas's infinitesimal change in temperature is dt, find the infinitesimal change in internal energy du of n moles of gas. express the infinitesimal change in internal energy in terms of given quantities.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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
