Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber.
a) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.300 m, what is the length of the fiber?
b) If a sample of gold with a mass of 1.475 g, is pressed into a leaf of 8.695 m thickness, what is the area of the leaf?
