Which statements are true about moving the compass around the wire? check all that apply.

with no current, the compass needle will not move.

if the light bulb is on, the compass needle will move.

if the circuit is on, compass needle movement will indicate a dead battery.

if current is flowing, the compass needle will not move unless the compass is touching the wire.

changing the battery terminals will change the current flow and the compass will point differently.

A, B, and E

Explanation:

i just took this

Explanation:

0.19 m/s and 0.45 m/s

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
