Assume the elevator is moving upward at increasing speed. Rank the magnitude of the forces. Rank from largest to smallest. To rank items as equivalent, overlap them.
1. the force of the 3kg block on the 2kg block, F3on2
2. the force of the 2kg block on the 3kg block, F2on3
3. the force of the 3kg block on the 1kg block, F3on1
4. the force of the 1kg block on the 3kg block, F1on3
5. the force of the 2kg block on the 1kg block, F2on1
6. the force of the 1kg block on the 2kg block, F1on2
7. force of the 1kg block on the floor, F1onfloor
8. force of the floor on the 1kg block, Fflooron1

would be false hope this out

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

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
