Answer to relevant QuestionsA rectangular steel column supports a load of 12.0 metric tons. If the column is 2.00 m in length before being stressed, what is the decrease in length? (a) Which of the liquids in Table 9.1 has the greatest compressibility? Why? (b) For equal volumes of ethyl alcohol and water, which would require more pressure to be compressed by 0.10%, and how many times more? If you dive to a depth of 10 m below the surface of a lake, (a) What is the pressure due to the water alone? (b) What is the absolute pressure at that depth? What is the fractional decrease in pressure when a barometer is raised 40.0 m to the top of a building? (Assume that the density of air is constant over that distance.) In 1960, the U. S. Navy’s bathyscaphe Trieste (a submersible) descended to a depth of 10 912 m (about 35 000 ft) into the Mariana Trench in the Pacific Ocean. (a) What was the pressure at that depth? (Assume that seawater ...
