Anyone know how to solve this? a houndred grams of iron (at a temperature of 90°c) gets in contact with 300g of aluminum (at a temperature of 25°c). determine the balance temperature cfe=0.11 cal/g.°c ,cal=0.22 cal/g.°c

the answer is c.)

explanation:

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

where is the circuit diagram ?

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
