The trombone's low B flat 2 is played with the slide in first position. What is its effective length, that is the length of an idealized closed tube with the same second mode frequency? Estimate how far the slide should be moved to reach second position in order to play A2...

The clarinet's lowest note is D3, 147 Hz. What is its effective length, that is, the length of an idealized closed pipe that has this frequency for its first mode? Explain why this is less than the actual length of the instrument?

Given that the oboe's lowest note is B flat 3 and its length approximately 64 cm, what length would you expect for the bassoon, whose lowest note is B flat 1? What length for the contrabassoon, lowest note b flat 0?

The mass of 1 cubic meter of air at sea level is about 1.3kg. Hoe much does it weight in newtons? How much would a stack of 8000 such cubes weigh? If this total weight were all applied to an area of 1m^2, how much pressure would it produce on that surface? The answer should lo...

A meteor streaking through the night sky is located with radar. At point A its coordinates are (5.20km,1.20km), and 1.16s later its has moved to point B with coordinates (6.08km, 0.900km ). a) find the x comonent of it average velocity between A and B. .759km/s b) y= .259 km/s...
