A long, straight, horizontal wire located on the equator carries a current (conventional) toward the west. What is the direction of the force on the wire due to the Earth’s magnetic field?

Answer and Explanation: To determine the direction of force, use Right Hand Rule:

Thumb is directed to the current. In this case, to the left;

Palm of the hand towards magnetic field. In this case, since it is Earth's magnetic field, it is pointing towards south;

Then, fingers are in the direction of Force, which is downward.

In conclusion, Force on the wire is directed Downward.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
