An elephant exerts a clockwise torque on a merry-go-round of 5.3 Nm while a rhino exerts a counterclockwise torque of 2.8 Nm on the same merry-go-round. What is the net torque on the merry-go-round

2.5 Nm clockwise

Explanation:

Given

Torque exerted by Elephant

Torque exerted by rhino

Therefore Net torque is Algebraic sum of two torques

Considering Clockwise to be Positive

Therefore  net torque on Merry-go-round is 2.5 Nm clockwise

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
