Once the magnet moved closest to the loop in the forward direction, under normal magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was mA.

Once the magnet moved closest to the loop in the reverse direction, under normal magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was mA.

Once the magnet moved closest to the loop in the forward direction, under reversed magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was mA.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

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

answer(20) psi;
