The field lines around one end of a bar magnet are shown below.
a vertical box labeled with a question mark. curved lines with arrowheads point into the top of the box from the top and sides.
based on the diagram, what can you conclude about the pole of the magnet?
it is a south pole because the field lines spread out from this end.
it is a north pole because the field lines spread out from this end.
it is a south pole because the field lines enter the magnet at this end.
it is a north pole because the field lines enter the magnet at this end.

Identify the balanced chemical equation that represents a decomposition reaction. p4 + 3o2 ⟶ p2o3 2fe(oh)3 ⟶ 2feo3 + h2o cuso4 ⟶ cuo + 2so3 2fe(oh)3 ⟶ fe2o3 + 3h2o

Type the letter that represents the correct location for each particle type below.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
