Water has a specific heat of 4.184
J/Kg°C. Wood has a specific heat
of 1.760 J/Kg°C. What material
needs more energy to raise the
temperature 1°C
.

Water needs more energy to raise temperature by 1°C

Explanation:

Specific heat energy is the energy needed for a material to raise its temperature by a degree. A material with higher specific heat energy needs more energy and a material with lower specific heat energy needs less energy.

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
