Hello, hello. I hope everyone had a great Thanksgiving long weekend. But here we are back in school.. go figure. I'm fairly new to this whole blog thing, so please.. be gentle.

In class we read over pages 3 to 6 in our yellow booklet, Sound Unit.

We also worked on the sound worksheet given to us in class and corrected it.
Here are the answers to the worksheet (only because I am soo nice)

1. longitudinal
2. pitch
3. 2.5 cm
4. long
5. a) behind b) 9 seconds
6. solids
7. 4 seconds
8. will not.. every other push will oppose the motion of the swing
9. 220 hertz
10. slightly different frequencies
11. 4 hertz
12. 332 m/s + (0.6)(20) = 344 m/s

Homework: Do questions 3, 4, 5, 7, 8, 9 and 10 in the yellow booklet.

Alrighty then, later days.
