An aluminum calorimeter cup has a mass of 67.0 grams. it contains 22.9 grams of water. the cup
and water are in thermal equilibrium at 24.5 degrees celsius. a 147 gram piece of steel with a
specific heat of 452 j/kg/c at an original temperature of 119 degrees celsius is added to the water
and cup. if no heat is lost to the environment, what will be the final temperature of the cup, water,
and steel when the three have reached thermal equilibrium?

i believe the answer is a

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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
