A thin U-tube with a horizontal length of 25 cm contains water. In the right branch, a 10 cm column of oil is poured. Determine the horizontal acceleration with which the U-tube must move so that the liquid levels in the two vertical branches are the same. If at a certain moment the tube stops accelerating and maintains a constant velocity, determine the height difference between the oil level and the water level in the two vertical tubes. Assume that the 10 cm column of oil is always in the vertical tube. Consider: Pwater 1000 kg/m³ and Poil = 750 kg/m³. = 3
