yeh i got the exact same answers

What was Q11?

[catweazle]

I got

BBCCCDCCBCBAA

[krzysiek]

Q11 was a question about pressure variation in an open ended tube, where it was vibrating at its fundamental frequency. It asked, at the midpoint P, what the standing wave looked like. It gave two choice of straight lines (for the midpoint P) and two choices of what looked like just normal looking sinusidal waves... I chose the one with a straight line as I thought at the point P there is a flat line, but hey.. who knows

[Slappo]

11 was the presure variation one on for first harmonic..
what was Q7?

[dekoyl]

I'm scared as heck. I turned my MC answers into a chant (so I can compare it on VN). Although I can't remember it correctly, my chant only comes up with 12 letters.. so if I were stupid enough to skip one MC and wrote question X in question (X-1)'s box... oh shit. Haha.

Why didn't u just write them down on your data sheet or your cheat sheat?

crap... yeh P is a node so it wont move, thus i am also wrong (N)

i dont reckon it was a straight line
im going with option A (fingers crossed)

[chelo]

i got the same aswell

[methodsboy]

^yeah chose A.
Since there's pressure changes at anti-nodes

[avram_grant]

wait... it is A... yes!

What was Q4?
