iron pyrite is oftern called fools gold. Suppose you have a solid that looks like gold, but you belive it to be fools gold. The sample has a mass of 23.5g. WHen the sample is lower into the water in a graduated cylinder the water level rises from 47.5 mL to 52.2 mL. Is the sample fools gold with a density of 5.00g/cm3 or real gold with a density of 19.3 g/cm3?

(Figure 1) shows a container with a cross section area of 15 cm² in which a layer of water floats on top of a layer of mercury. A 1.0 kg wood block with a cross-section area of 10 cm² floats on the water. The water depth, measured from the bottom of the block, is 25 cm. A pressure gauge at the bottom of the container reads 20 kPa. Figure 1.0 kg 25 cm h 10 cm² 15 cm² 1 of 1 > Part A = What is the depth dm of the mercury? Use pw = 1000 kg/m³ as the density of water and pm density of mercury.

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A, of 9.8 cm², and the right arm has a cross-sectional area A, of 5.50 cm². Two hundred gra 8 ст of water are then poured into the right arm as shown in Figure b. Water A1 Ag A1 Mercury Densities: Mercury 13.6 g/cm³, Water 1.0 g/cm³ (a) Determine the length of the water column in the right arm of the U-tube. cm (b) What distance h does the mercury rise in the left arm? cm. (c) In figure b, at the level of the dashed line, which side of the u-tube has larger pressure? O Mecure side Water side Same
