The figure below shows the spectra of two galaxies A and B.  Please can i get help  with this questions below:  1. Which of these galaxies has ongoing star formation? How can you tell?2. One of these galaxies has Hubble type E3 while the other is SBb. Which is which? What does the 3 inE3 tell you about the galaxy? What does the SB in SBb tell you about the galaxy?3. What effects would dust have on the two spectra?4. Which galaxy would you expect to have more far-infrared emission? Expl
As we discussed, clouds are made of a great many small drops. Really - a great many. Imagine a liquid cloud that fills a volume of 1 km3. The clouds contains 100 drops per cubic centimeter; for the sake of argument assume that each is 10 microns (micrometers) in radius. A. How many drops does the cloud contain? Compare this to a big number - say, the number of stars in the galaxy. B. What mass of water does the cloud contain? Compare this to something big - elephants, trucks, that sort of thing. C. What fraction of the cloud volume is filled with condensed water? One way to approach this is to compare the density of the suspended liquid water to the density of the surrounding air. D. How many 1 mm drizzle drops could you make from all the cloud drops? E. How much energy was released when this water condensed from vapor to liquid? If the water condensed in 20 minutes (a reasonable lifetime for a small cloud), what was the (energy per time)? power
Which of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices   Most M stars end up as neutron stars or black holes.   The lifetime of M stars is longer than the age of the universe.   Most M stars are located near the edge of the universe, beyond the visible horizon.   Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion.   White dwarfs are too dim to be observed with currently available techniques.
