Homework Help: PHYSICS

A) As a wind instrument warms up, the resonant frequencies of the instrument tend to slightly decrease.
B) If the air in a concert hall warms up, the resonant frequencies of the string instruments will change precisely the same as the resonant frequencies of the wind instruments.
C) If you pluck a string one third of the way along its length, you tend to suppress the third harmonic (n=3).
D) If the slide of a trombone is pushed outwards (making the effective tube length longer), all the resonant frequencies of the instrument increase.

I thought the answer was TTFF, but it was wrong. Any idea?

speed sound decreases when air is warmed. If speed goes up, frequency decreases A)T
B. strings slightly expand, reducing tension, so f goes down,but not at the same rate, F
C. T. The third homonic would a node at that position, you are forcing a vibration there.
D. length longer, wavelength longer, Freq decrease. F

Check my thinking.

Its actually FFTF, thanks for the help
