On another planet that you are exploring, a large tank is open to the atmosphere and contains ethanol. A horizontal pipe of cross-sectional area 7.0×10−4m27.0×10−4m2 has one end inserted into the tank just above the bottom of the tank. The other end of the pipe is open to the atmosphere. The viscosity of the ethanol can be neglected. You measure the volume flow rate of the ethanol from the tank as a function of the depth hh of the ethanol in the tank. If you graph the volume flow rate squared as a function of hh, your data lie close to a straight line that has slope 2.09×10−5m5/s22.09×10−5m5/s2. What is the value of gg, the acceleration of a free-falling object at the surface of the planet? Express your answer with the appropriate units.

A proud yacht owner makes an anchor from 145 kg of pure gold. a) If gold has a density of 19,600 kg/m3, calculate the volume of this anchor. b) When the golden anchor is stored inside the yacht, the water's buoyant force must support the anchor. Calculate the volume of water that the anchor displaces when it is stored inside the boat. c) Based on your answers to parts a) and b), why do shipping companies struggle to transport large quantities of solid metal across oceans?
