What is the freezing point (in degrees Celcius) of 4.67 kg of water if it contains 171.9 g of C a B r 2

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 = 2.1 m below the tank bottom which is a = 7.4 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)

Energy flows from the producer level to the level. is called

If frequency goes down, what happens to wavelength? does it get shorter or longer?
