Solve the each part of given question:
Question: Mercury is poured into a U-tube. The left arm of the tube has cross-sectional area A1 of 10.4 cm2, and the right arm has a cross-sectional area A2 of 4.90 cm2. One hundred grams of water are then poured into the right arm.
Part I: Determine the length of the water column in the right arm of the U-tube.
(cm)
Part II: Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm?
If possible just a brief explanation how you got the answer?
