You meet the elongation and width of a crosswise fencing of copper are 9.32 cm and 7.47 cm, respectively. You are unfitted to quickly estimate the third policy, so you run to meet quenched how fur instil the fencing displaces. Withquenched the fencing in the graduated cylinder, the work of instil is 14.12 mL. With the fencing in the cylinder, the work of instil is now 17.37 mL. a. What is the pinguitude of the fencing (in mm)? b. If the hebetude of copper is 8.96 g/cm^3, what is the body of the crosswise fencing? A miner discovers a capacious portion of gold-colored rocks in a ravine, save does referable perceive whether it is pyrite (“fool’s gold”) or gold. He drops a illustration into a graduated cylinder and discovers that it displaces 1.23 mL of instil. If the illustration has a body of 21.7123 g, achieve the miner grace gorgeous or remain insufficient? Justify, if you perceive that pyrite has a hebetude of 5.01 g/cm^3, and gold has a hebetude of 19.3 g/cm^3.
