If you take any pitch on the keyboard, the next occurrence of the same letter name going towards the left (down) will vibrate:

Select one:
A. Twice as slow
B. Twice as fast
C. At 256 Hz plus the harmonic of the first pitch
D. At twice the speed minus the square root of the first pitch.

Apossible explanation for a set of facts that can be tested by further investigation is called

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
