Homework Answers
None of the given sets of metals has Equal Density.
Options B,C,D,E are practically impossible to have an Equal Density, at First Sight, No Calculation needs to be done, for these 4 options. Only Option A seems to have an Equal Density and needs Calculation, but after Calculation, it's evident that Option A also contains the set of 2different Densities of Metals.

Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...

Bonus-1 point) According to Vitruvius, a new crown in the shape of a laurel wreath had been made for King Hiero lII, and Archimedes was asked to determine whether it was of solid gold, or whether silver had been added by a dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down. While taking a bath, he noticed that the level of the water rose as he got in. He realized...
