In a spectral line from a rotating body such as a star, some of the matter emitting the line is moving toward you and has a part of its line shifted slightly to the bluer end of the spectrum, some is moving away and has a slight shift toward the red end, and the rest is moving more or less across your line of sight and the shift is normal.

What makes some paper towels absorb more water than others?
some paper towls are thicker
How might the difference in the brightness of spectral lines be explained?
either a) "jump" from a lower energy level to a higher energy level. -=NOT THIS ONE=- b) "jump" from a higher energy level to a lower energy level. c) "jump" from a ground state to an excited state. d) None of the Above
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.
If solubility is a propety of a substance explain why some substance will dissolve in some substasnce but no others?
because the solubility is a propety of a substance and some substance will dissolve in some substasnce but no others
Why is it more important to recycle some materials than others?
It is important because some materials take longer to decompose than others
Does Every element and compound in nature have a unique set of spectral lines?
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
What are the dark lines in a stellar spectrum are called?
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
How was helium identified on the sun with a spectroscope?
Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.
What makes some paper towels absorb more water than others?
some paper towls are thicker
What does Neptune's rings do?
The particles bunch up in some areas so they are thicker in some places than others
Are some pennies thicker than others?
yes; if you look closely it is very easy to tell
Why do people have monobrows?
Some people just have eyebrows that tend to grow more thickly in the center than others do, just as some have thicker hair on their head than others do.

How can I see an line spectrum from a cloud of gas?
If there is a star shining through the gas then some of the starlight will be absorbed by the gas to deliver spectral lines of the "stuff" making up the gas.
Why are some power cords thicker than others?
It has to do with current requirements of whatever you plug into it. Things that heat up require a thicker cord to transport the current. A thinner cord may overheat.
Is a hoop earring thicker than a lip ring?
It depends how large it is, some of them are and others aren't Hoped I helped.<3
How thick were castle walls?
Some were thicker than others. It also depended on how protected you want your castle to be. Also if you had enough money.
