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!
Extra Credit (2 Points): Go to the class web page and explore the link Computer Programs located just below "Material to Help You Out". Use the "Astronomical Distances" program to help check your answer for P7 from the Preview. How fast can you make the spaceship travel? How quickly can you get to the nearest star?
Extra Credit (2 Points): Go to the class web page and follow the "What's My Grade Right Now?" link. Tell me how you are doing in ASTR100 so far! The "What's My Grade?" page will be updated continually throughout the semester.
Extra Credit (4 Points): Go to the
Computer Programs
link from the main class web page (under Material to Help You
out). Run the "Scientific Notation" program until you are sure that
you can do this type of problem in your sleep (or on a midterm!). What
happens when you get a problem right? Do the same for the "Working
with Equations" program. Who wrote this program? If you have trouble
doing either of these problems, be sure to talk to your TA about
it. These are the ONLY type of math problems that I will ask you to do on
a test.
Extra Credit (4 Points): Go to the
Supplementary Information link from the main class web page (under
Material to Help You out). Pick a few sections, look through the
material, and try at least one quiz. This is an excellent way to start
studying for a midterm! Tell me which section(s) you looked at, and
how many questions you got right and wrong. If you answered any
questions wrong, be sure to read the corrected quiz carefully!
Extra Credit (4 Points): Follow one of the
SOLAR SYSTEM links from the main class web page (under Material to
Help You out). 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 (4 Points): Feeling stressed? Slam some
asteroids and comets into the Earth and see what happens on the "Solar
System Collisions" webpage (Follow the
Computer Programs 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 (4 Points): Follow one of the STARS &
OUR GALAXY links from the main class web page (under Material to
Help You out). 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 (4 Points): Follow one of the
OTHER
GALAXIES links from the main class web page (under Material
to Help You out). Explore some of the sublinks, and write a paragraph
summarizing what you find, and a paragraph describing what you learned
(Use your own words!)
