The appropriate electrical analogy in electric systems to the difference in height of a fluid-flow system is:

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.

explanation:

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

overcharge is the right answer system

this would be about 43%
