Describe how the relative density of a salt solution can be determined using the hydrometer

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

The air that we breath is made mostly of which gaseous molecule

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.
