1) Two bodies made of the same material have the same external dimensions and appearance, but one is solid and the other is hollow. When they are heated, for the same change in temperature is the overall volume expansion the same or different? 2) Two bodies made of the same material have the same external dimensions and appearance, but one is solid and the other is hollow.

Both the questions are different. Plz ans it fast

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.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
