- An iceberg that floats with 88.5% of its volume submerged in seawater of density 1060 kg/m^3. if the iceberg were to drift to a region where the seawater was less salty and only had a density of 1020 kg/m^3, how much of the iceberg would be submerged?arrow_forwardSuppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.495 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05 × 103 kg/m3. Calculate the systolic pressure you would observe, in units of mm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the to (and greater) number is systolic pressure. Ps? Calculate the diastolic pressure you would observe, in unites of mm Hg, if the pressure at heart was 120 overc80cmm Hg.
