Today we...

Had another substitute teacher!!!

The first thing that occurred was that he gave us the answers to the Universal Law of Gravitation worksheet.
Afterwards he gave us a few handouts and assignments.
We got an information sheet called, "Mass of a Central Object and Radius of Motion of a Satellite". According to the sheet itself, we can determine the mass of our sun by knowing the mean radius of orbit and period of motion of our own earth.
From the Green Textbook, we are to do problems number 6, 7, 11, 13, and 18 on page 172.
We also got a review sheet where we have to do questions 1, 2, 3, 5, and 6 only.

That is it, that is all. Remember, no classes tomorrow afternoon. Have fun on your day off and don't forget to do your homework!
