A person hums into the top of a well (tube open at only one end) and finds that standing waves are established at frequencies of 29.2, 48.6, and 68.1 Hz. The frequency of 29.2 Hz is not necessarily the fundamental frequency. The speed of sound is 343 m/s. How deep is the well

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
