Aflat, rectangular coil measuring 0.10 m by 0.20m and containing 100 turms of wire is rotating at a constant speed of 100m rad/s in a magnetic field of 0.20 t. the maximum emf induced in this coil is approximately: a) 126 v b) 63 v c) 1.0 v d) 10 v e) 44 v

probably not if net force is zero

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
