Unformatted text preview: hinojosa (jlh3938) oldhomework 41 Turner (58185) 1 This printout should have 7 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points A simple Utube that is open at both ends is partially filled with a heavy liquid of density 1000 kg / m 3 . A liquid of density 349 kg / m 3 is then poured into one arm of the tube, forming a column 14 cm in height, as shown. h 14 cm light liquid 349 kg / m 3 heavy liquid 1000 kg / m 3 What is the difference in the heights of the two liquid surfaces? Correct answer: 9 . 114 cm. Explanation: Let : = 14 cm , = 349 kg / m 3 , and h = 1000 kg / m 3 . Because the liquid in the Utube is static, the pressure exerted by the heavy liquid col umn of height  h in the left branch of the tube must balance the pressure exerted by the liquid of height h poured into the right branch, so P + (  h ) h g = P + g . h = parenleftbigg 1 h parenrightbigg = (14 cm) parenleftbigg 1 349 kg / m 3 1000 kg / m 3 parenrightbigg = 9 . 114 cm ....
