The rube goldberg device included in the lab is, an example of a closed system because all of the matter (such as the string, the ball and the books) stayed in the area. however the potential energy, that was stored in the ball on the high shelf and suspended weights as well as the stored mechanical energy of the sling shot, had left the system in the form of sound, motion and heat. now, take a look at the device you created and explain what type of energy system (open, closed or isolated) is represented by the lab device and why?

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)
