Homework Help: Physics _ Please please help

Posted by Sonya on Wednesday, August 10, 2011 at 3:14pm.

The cross-sectional area of the U-tube shown below is uniform and is equal to one square centimeter (1.00cm^2). One end is open to the atmosphere. Atmosphere pressure may be taken as P1=1.01 * 10^5 Pa. The other end of the U-tube is connected to a pipe in which a constant gas pressure of P2=1.25 atmospheres is maintained. The U-tube contains a liquid which has a density of 1.0*10^4kg/m^3.

(I) Calculate the difference in height, h, in centimeters, of the eater levels in the two arms of the tube.

(II) 10 cm^3 of a liquid which has a density of 0.85 times that of the first liquid are now poured into the arm which is open to the atmosphere (assume that the liquids do NOT mix) What is the new difference between the liquid levels in the two tubes, assuming the pressures p1 and p2 remain constant?

(III) What the second liquid still in the arm that is open to the atmosphere, the pressure p2 is now reduced until it is equal to atmospheric pressure. What now is the difference (if any) between the liquid levels in the two arms of the U-tube?
