Resolved Question: TONS OF SPACE QUESTIONS #2?
11. Why do we call dark matter “dark”?
a. It emits light of other wavelengths, but not at visible wavelengths.
b. We cannot detect the type of radiation that it emits.
c. It emits no or very little radiation of any wavelength and it doesn’t reflect light.
d. It blocks out the light of stars in a galaxy.

12. What evidence suggests that the Milky Way contains dark matter?
a. We observe clouds of atomic hydrogen far from the galactic center orbiting the galaxy at unexpectedly high speeds, higher speeds than they would have if they felt only the gravitational attraction from objects that we can see.
b. We see many lanes of dark material blocking out the light of stars behind them along the band of the Milky Way.
c. We see many dark voids between the stars in the halo of the Milky Way.
d. When we observe in different wavelengths, such as infrared or radio, we see objects that don’t appear in visible-light observations.
e. When we look at the galactic center, we are able to observe a large black hole that is composed of dark matter.

13. The distribution of the dark matter in a spiral galaxy is
a. approximately spherical and about the same size as the galaxy halo.
b. approximately spherical and about ten times the size of the galaxy halo.
c. flattened in a disk and about the same size as the stellar disk.
d. flattened in a disk but about ten times larger than the stellar disk.
e. predominantly concentrated in the spiral arms.

14. How do we determine the amount of dark matter in elliptical galaxies?
a. We measure the orbital velocities of star-forming gas clouds around the outer portions of the galaxy.
b. We measure the speeds of stars at different radii from the galactic center and determine how much mass is interior to the orbit.
c. We count the number of stars in the galaxy and determine its volume, so that we can calculate the galaxy’s density.
d. We search for dark lanes of dust and black holes within the galaxy.
e. We measure how fast the galaxy rotates as a whole.

15. Which of the following is not evidence for dark matter?
a. the flat rotation curves of spiral galaxies
b. the broadening of absorption lines in an elliptical galaxy’s spectrum
c. X-ray observations of hot gas in galaxy clusters
d. gravitational lensing around galaxy clusters
e. the fact that the universe is expanding

16. Dark energy
a. may be the missing piece that halts the cosmic expansion, causing it to re-collapse
b. is driving the expansion of the universe at an accelerating rate.
c. is known as a common form of energy created in particle accelerator laboratories.
d. None of the above is correct.

17. A universe that is more than critical density, that has a closed geometry will
a. continue to expand forever, but will always be at the threshold of collapse.
b. continue to expand forever at an accelerated rate.
c. collapse at some time in the future.
d. will settle into a static state where the expansion halts, but will not collapse.
e. None of the above.

18. Methods for detecting the composition of dark matter
a. involve attempts to detect machos through their gravitational lensing of more-distant starlight.
b. involve attempts at direct detection of wimps using cold germanium crystals.
c. involve attempts at indirect detection of very high energy neutrinos created by annihilating wimps inside massive bodies like the Sun.
d. show that only a very small percentage of dark matter, if any, can be attributed to machos.
e. All the above are true.

19. Based on recent findings, which of the following statements are false about the mass/energy budget of the universe?
a. 95% of the content of the universe is a complete mystery to us so far as what the nature of this stuff is.
b. Stars, galaxies, gas and dust, particles comprise less than 5% of the mass/energy budget of the universe.
c. Dark matter makes up about 23% of the mass/energy budget of the universe.
d. Dark energy makes up about 73% of the mass/energy budget of the universe.
e. All the above is correct.

20. Which of the following is not an important reason for understanding dark matter and dark energy?
a. Most of the universe is made of these two dark components.
b. Dark matter has the greatest influence on the motions of stars in galaxies and galaxies in clusters
c. Dark energy may have the greatest influence on the fate of the universe.
d. Learning what the nature of these components are may revolutionize our understanding of physics.
e. Dark energy is currently working to expand our solar system, which may result in the end of life on Earth in the next few bil

Resolved Question: Ketones? Chemists out there, help! Appreciated. ^-^?
So I’m an A level Chemistry student and I’m stuck.
Absolute despise the Methods of Analysis and Detection book, so no surprises there.
Basically, I’m given the graphs of; mass spectrometry, i.r (infrared) and n.m.r (nuclear magnetic resonance) spectrum and am meant to work out the compound given from those.
Thankfully, I’m not too hopeless so have figured out it’s a ketone compound with molecular mass of 86.
Also I’ve drawn a little table with the following information:

Chemical Shift
0.7 – 1.6
3.3 – 4.3

Number of Protons
6
4

Splitting pattern
triplet
quartet

So basically, it has 10 hydrogens and - O - CH3 OR -O-CH2-R somewhere in the compound.
Any ideas? Highly appreciated!
