Now you should be easily able to work the following questions and
problems. Always put your name and section number at the top of your
homework!
Last Question. Go to the class web page and explore
the link Astronomy
Classroom located immediately below "The Astronomy Workshop". Run the
"Scientific Notation" program until you are sure that you can do the
"Convert" problems in your sleep (or on a midterm, so don't use a
calculator!). Now take the conversion quiz (you may retake it as many
times as you'd like),
Take a screenshot
of your results and hand it in with the rest of your homework.
Extra Credit (2 Points): Find the "Astronomical
Distances" program in the same area of the Astronomy Workshop. How
fast can you make the spaceship travel? How quickly can you get to the
nearest star?
Extra Credit (2 Points): Now check out the
"Working with Equations" program. What are all of the variables in the
two equations that contain "GM"? Check those two boxes and try the
program. If you have trouble doing either of these problems, be sure
to talk to your TA about it. This and Scientific Notation are the
ONLY type of math problems that I will ask you to do on a test.
Type your homework up in Microsoft Word, Mac's Pages or another text
editing program. Be sure to show all work for math problems. When
done, convert to PDF and submit
a single homework file
to
http://janus.astro.umd.edu/datadir/ed/15f/homework/ by
the 11:00am deadline. You may
submit your homework multiple times; the last of your submissions
before the deadline is the one that will count. All homeworks should
be prepared and submitted in this way. Converting to PDF is easy:
Extra Credit (2 Points):
Go to the
Astronomy Classroom link from the main class web page (under
"The Astronomy Workshop"). Run the "Scientific Notation" program with the
"Practice Multiply/Divide" until you are sure that you can do this
type of problem in your sleep (or on a midterm!). Now take the
Multiply/Divide quiz,
take a screenshot
and hand it in with the rest of your homework. Please submit your entire homework
assignment online as a single PDF file.
A Good Idea: Test Yourself! Do some of the Quick
Quizzes for the five chapters that will be on the midterm and see how
you do! This is an excellent way to start studying for a midterm! You
might also check out the
Supplementary Information link from the main class web page (under
"GENERAL"). Pick a few sections, look through the material, and
try at least one quiz. If you answered any questions wrong, be sure
to read the corrected quiz carefully!
Extra Credit (2 Points): Follow one of the
SOLAR SYSTEM links from the main class web page (under "Useful
Links"). Explore some of the sublinks, and write a paragraph
summarizing what you find, and a paragraph describing what you learned
(Use your own words!)
Extra Credit (2 Points): Feeling stressed? Slam some
asteroids and comets into the Earth and see what happens on the "Solar
System Collisions" webpage (Follow the
Explore the Possibilities link). Describe what happens -- and how often
-- for asteroids of several different sizes (small, medium, large,
HUGE!). Imagine a rocky asteroid moving at 20 km/s, how big does it
have to be to create a magnitude 9.5 earthquake?
Extra Credit (2 Points): Follow one of the STARS &
STELLAR REMNANTS links from the main class web page (under "Useful
Links"). Explore some of the sublinks, and write a paragraph
summarizing what you find, and a paragraph describing what you learned
(Use your own words!)
Extra Credit (2 Points): Follow one of the GALAXIES
links from the main class web page (under "Useful Links"). Explore
some of the sublinks, and write a paragraph summarizing what you find,
and a paragraph describing what you learned (Use your own words!)
Homework #1 (10 Points) Due Tuesday Sep. 22, by 11:00am
Before starting this homework, please
read chapters 1, 2, and 3. Be sure
to try the "Quick Quiz" at the end of each chapter (answers are on
page A-13 in the old textbook) - this is a great way to see if you are
absorbing the material. It is also an excellent way to practice for
the exams, which will include some multiple choice questions eerily
similar to these ones. I recommend doing this for each of the chapters
as you read them and again before exams.
