While analyzing a sample of ore, a geologist finds that it weighs 2.00 N in air and 1.13 N when immersed in water. Calculate the density of the ore.

Five containers each hold the same volume of various liquids. Five blocks composed of various solids are fully submerged, one in each of the five containers. The blocks all have the same size and are all held at the same depth in the containers. The volume of each block is one-fourth the volume of the liquids in the containers. Container A has a block mass of 0.04 kg, and a liquid mass of 0.19 kg Container B has a block mass of 0.02 kg , and a liquid mass of 0.11 kg Container C has a block mass of 0.03 kg , and a liquid mass of 0.14 kg Container D has a block mass of 0.02 kg , and a liquid mass of 0.16 kg Container E has a block mass of 0.04 kg , and a liquid mass of 0.15 kg Which formula would I need to use in order to rank the buoyant forces from largest to smallest in this circumstance?

A block of wood floats in fresh water with 0.694 of its volume V submerged and in oil with 0.924 V submerged. Find the density of (a) the wood and (b) the oil.

A sphygmomanometer is a device used to measure blood pressure, typically consisting of an inflatable cuff and a manometer used to measure air pressure in the cuff. In a mercury sphygmomanometer, blood pressure is related to the difference in helghts between two columns of mercury. The mercury sphygmomanometer shown in the figure below contains air at the cuff pressure P. Po The difference in mercury heights between the left tube and the right tube is h= 109 mmtg - 0.109 m, a normal systolic reading. What is the gauge systolic blood pressure Poauge in pascals? The density of mercury is p 13.6 x 10 kg/m and the ambient pressure is Po1.01 x 10 Pa. HINT Pa
