5-6. An engineer tried to weld a highly conductive   gold film (0.250 cm thick) to a silicon substrate to make a mother board that can survive high-impact forces.
Assuming the gold has a density of 19.3 g/cm
3, silicon has a density of 2.33 g/cm3, and the structure has a uniform thickness of 1.00 cm into the page, calculate (a) the centroid of the component relative to the coordinate system shown. (b) the center of mass of the component relative to the coordinate system shown. [10 marks]
