11. (5 points) Figure 4 shows a U-tube is filled with water, and the two arms capped. The tube is cylindrical, and the right arm has twice the area of the left arm. The caps have negligible mass, are watertight, and can freely slide up and down the tube. A 1-kg block is placed on each cap. (A) (B) Figure 4 What is the mass of the water m located in the right arm between the dashed line and the right cap? (A) 1 kg (B) 9 kg (C) 8 kg (D) 2 kg (E) 3 kg 12. (5 points) Two liquids, Liquid 1 with density p₁ = 1000 kg/m³ and Liquid 2 with density p2, are in equilibrium in a U-tube that is open at both ends, as shown in Figure 5. The liquids do not mix, and Liquid 2 rests on top of Liquid 1. Liquid H (P1 = 1000 kg/m³) |hi = 0.08 m h₂ = 0.10 m Liquid 2 (P₂ = ?) Figure 5 If the heights of Liquid 1 and Liquid 2 are as shown in Figure 5, the density of Liquid 2 is (A) 1000 kg/m³ (B) 1260 kg/m³ (C) 900 kg/m³ (D) 800 kg/m³
