A U-Tube with a Cross-Sectional Area of 1

question 83

Short Answer

A U-tube with a cross-sectional area of 1.00 cm² 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 cm³ of oil is poured into one end. As a result, the top surface of the oil ends up 0.550 cm higher than the water surface on the other side of the U. What is the density of the oil?
