Examine the scenario.

1)Two different objects are brought close to one another. The objects pull, or attract, each other.

Which choice correctly identifies the pole(s) that could be interacting?

The poles must be the same, either north and north, or south and south. Like poles attract each other.
One of the objects must have its north pole directed toward a non-magnetic object. A north pole always repels non-magnetic objects.
One of the objects must have its south pole directed toward a non-magnetic object. A south pole always repels non-magnetic objects.
The poles must be opposite, such as north and south. Opposite poles attract each other.

2) Which of the following correctly describes a step-down transformer?
(Select all that apply)

has a higher voltage on the secondary than the primary
used to decrease the voltage that comes out of the transformer
has greater number of windings on the secondary than the primary
has a higher voltage on the primary than the secondary

3) Which of the following choices correctly identifies the process created by moving a magnet through a conducting loop?

conduction
transformation
electromagnetic induction
magnetic field generation

4) Examine the scenario.

A charged particle is placed in Object A’s electric field.

Which choice correctly describes a factor that would strengthen the force the particle experiences in the electric field?

Decrease the magnitude of the charge of Object A.
Increase the distance between the particle and Object A.
Increase the mass of the particle.
Bring the particle closer to Object A.

5) Which choice is correctly defined as a field surrounding an object that is directed away from the north pole and towards the south pole?

matter field
electric field
magnetic field
gravitational field

1. 1. I assume the question has to do with magnets since all of the answers are for magnets. D is correct.
2. B and D

Those are the only freebies I'm willing to give you on these. Frankly I think this material is in your notes/lectures/textbook. Telling me you're not very good at science won't get it. You could be good, at least better, if you would read and answer these yourself. Please go through the text/notes/etc and answer. Someone will be happy to check your work.
