Homework Help: Physics

Posted by Victor on Monday, December 3, 2012 at 9:57pm.

Archimedes purportedly used his principle to verify that the king's crown was pure gold, by weighing the crown while it was submerged in water. Suppose the crown's actual weight was 14.0 N. The densities of gold, silver, and water are 19.3 g/cm^3, 10.5 g/cm^3, and 1.00 g/cm^3, respectively.

(a) What would be the crown's apparent weight if it were made of pure gold?

(b) What would be its apparent weight if it were made of 80% gold and 20% silver, by volume?
