A u-tube with a cross-sectional area of 1.00 cm^2 is open to the atmosphere at both ends. WAter is poured into the tube until the water rises part way along the straight sides, and then 5.00 cm^3 of oil is poured into one end. As a result, the top surface of the oil ends up .550 cm higher than the water surface on the other side of the U. What is the density of the oil?Type your question here.
