Why do stars form in groups instead of alone? Suppose a cluster of stars formed 3 million years ago. Why would you expect the H-R diagram of the cluster to show no stars on either the very high-mass end of the main sequence or its very low-mass end?
Calculate and compare the distance of two stars (absolute magnitude of -2) with apparent magnitudes of 6 and 12, respectively.

How can you determine the age of a star cluster in which all stars formed at the same time?

How can you determine the age of a star cluster in which all stars formed at the same time? (hint: think about the main sequence of stars and which stars evolve how quickly) Does the expanding universe expand into something? Is there a center from which the universe expands?

What are the advantages of a form being formed as a limited liability company (LLC) instead of a limited partnership? Any disadvantages? Three individuals recently created a LLC, with equal interest. One will be working in the business as manager and will receive a salary of $60,000; all will have substantial income from other sources. The LLC expects to be profitable and will earn approximately $30,000 of ordinary income and $30,000 or long-term capital gain. What tax issues should the...
