Really? Would you mind scanning and uploading/taking photos, or even just writing the wording of some of the questions for us? I think everyone would find that really helpful and it would solve quite a few debates :P

only noobs do physics b :smile:
You could kinda work out the springs. If they are in parrallel then the extension is halved as the force is shared. In series it doubles the extension. I only knew this because i read it from the book and took notes. Lucky!

Everyone seems to be 'arguing' the stationary wave phase difference. I wrote 180 then 360. Is this right or wrong? Haha!

yeah!! you really should do the spring one please.
Does it matter how many sig figs we give answers to in questions where it didn't specify to put the answer to an appropriate number of sig figs? Cos I did that for quite a few questions and varied how many sig figs my answers were given to.

yea basically ignore my comment xD



Still valid input though thanks :smile:

Though, i can't even remember, did the question say that it must be a spring??

The spring one, the one about stationary waves, and maybe the last page as well. That would be wonderful, you're a doll. :P
