J8. over several cycles, a refrigerator compressor does work on the refrigerant. this work is equivalent to a constant pressure of 413 × 105 pa compressing a circular piston with a radius of 0,.019 m a distance of 25.0 m. if the change in the refrigerant's internal energy is 0 j after each cycle, how much heat will the refrigerant remove from within the refrigerator?

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

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.

conduct current i mean it makes sense
