Acompass needle normally points toward earth’s magnetic pole, which is near the north pole. which best explains why the needle moves away from the pole when it comes close to a current-carrying wire? current within the wire weakens the magnetic force of the pole. magnetism surrounding the wire weakens the magnetic force of the pole. current within the wire draws the needle toward the wire. magnetism surrounding the wire draws the needle toward the wire.

Magnetism surrounding the wire draws the needle toward the wire.

Explanation:

As we know that the magnetic field due to current carrying long wire near a point of wire is given by

here we know that

i = current in the wire

r = distance from the wire

now when we place the wire near the compass then the magnetic field produced by the wire will attract the compass towards the wire and due to this the needle will come closer to the wire

so here correct answer will be

Magnetism surrounding the wire draws the needle toward the wire.

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
