The left arm of the tube has a cross-sectional area of A1=10 cm2, and the right arm has a cross-sectional area of A2=5 cm2. One hundred grams of water are then poured into the right arm.
(a) Determine the length of the water column in the right arm of the U-tube.
(b) Given that the density of mercury is 13.6 g/cm3, what distance, h, does the mercury rise in the left arm?
