Question

Part II A U-shaped tube (height 0.5 meter) is partly filled with water, as shown at right. The right end of the tube is closed at the top, but the left end is open to the atmosphere. There is no air between the rubber stopper and the water surface on the right-hand side. Question 3. Rank the pressures at points W, X, Y, and Z from largest to smallest. If any of the pressures are equal, state that explicitly. (For example: W-X>Y-Z) Question 4. Explain the reasoning you used to answer the previous question Question 5. Is the pressure at point Z greater than, less than, or equal to atmospheric pressure? O Greater Than O Less Than O Equal To Question 6. Explain the reasoning you used to answer the previous question

Answer 1

P_A atmospheric pressure P_x = P_A = X (i) P_w implies P_A + rho_w g times h_1 < P_X II rho_w = water density P_y = P_x (Both are At same horizontal level) (III) P_z = P_y - rho_w gh_2 P_w > P_x = P_y > z W > X = Y > Z just Above written. X OR P_X = P_Atmosphere W implies X + rho_w gh_1 Y = X Z = Y - (rho_w) gh_2 compare all. \r\n As Z = P_A - rho_w gh_2 P_A - Atmospheric pressure so from here we see P_A > Z Lessthan As Reason Z = P_A - rho_w gh_2
