Hello everybody. This shall possibly be my last official scribe post for this blog. In addition, today is a big day. It is the day that marks the intervention of having a one month anniversary of blogging absences for this blog. It is also the day that precedes our Gravitational-Electric Fields Test. Good luck to everyone on that. As for what happened today in class, we went through a couple of worksheets and problems. Here is a concise summation of the essential bits gone through below.

We wholly went through Gravitation Fields Review - Worksheet. There exists three sample questions with answers at the very bottom of the last page. Be sure to check that out.

We went through Chapter 2: Motion - Exercise 2-1. Answers are as follows:
1. Greyhound speed=16m/s, Gazelle time=0.01s, and Turtle distance=30cm.
2. a) The BB is gaining distance and speed in each successive time interval.
b) Yes, distance is directly proportional to T^2 (time squared)
c) Distance Fallen: 1, 4, 9
d) Yes; 9cm, 11cm, 13cm. Distance Fallen: 1, 3, 5, 7
e) odd
3. a) 10, acceleration
b) time
c) 70m/s, 245, 10

Green Textbook Questions *forgot pages*
1) 20000 N/C
2) 7 x 10^-5 C
3) 4.44 x 10^-7 C
17. a) 1.6 x 10^-18 C
b) N = 10 electrons

In pre-conclusion, we received Chapter 24: Study Guide - 24.1 Magnets: Permanent and Temporary, The Earth's Magnetic Field, and 1.3 Magnetic Poles worksheets. Oh yeah, people need to scribe. I initially was just going to let the next scribe be anyone that needed to scribe, but seeing as how I took initiative after so many days, I shall choose a person so that they are obligated to scribe. Well hopefully they commit. Hmm. Roses are red, violets are blue, no available scribe name rhymes with blue, so Lynel I choose you :P
