The lowest note on a grand piano has a frequency of 27.5 hz. the entire string is 2.00 m long and has a mass of 440g . the vibrating section of the string is 1.75m long. what tension is needed to tune this string properly?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
