Moving a wire through a magnetic field created by two stationary permanent magnets will...: cause the magnets to move.

create a current through the wire.

produce no visible effect.

cause the magnetic field to flow in the opposite direction.

B.

Explanation:

Given that a Moving a wire through a magnetic field created by two stationary permanent magnets will...:cause the magnets to move.

create a current through the wire.

produce no visible effect.

cause the magnetic field to flow in the opposite direction.

According to faraday's law, the EMF will be induced. And the induced EMF will definitely create electric current through the wire.

Therefore, option B is the best answer.

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
