If stretching a spring 3.50m causes a force of 20.0N, what is the constant of the spring? A. 16.5N/m
B. 23.5N/m
C. 5.71N/m
D. 70.ON/m ​

k = 5.71 N/m

Explanation:

k = F/Δx = 20.0/3.50 = 5.71 N/m   which is almost nothing as far as a spring goes.

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

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
