Academics

Gold which has a density of 19.32g/cm³,is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber

(a) If a sample of gold with a mass of 6.400gm is pressed into a leaf of 4.720µm thickness, what is the area of the leaf.

(b) If instead the gold is drawn out into a cylinder fiber of radius 2.8µm, what is the length of the fiber?
