You strike a tuning fork and find that the first harmonic/fundamental resonance is produced when the air column length or height or depth
at 0.166 m. If the speed of sound is 340 m/s, what is the frequency of sound wave produced by the tuning fork in Hz?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
