You, archimedes, suspect that the king’s crown is not solid gold but is instead gold-plated lead. to test your theory, you weigh the crown, and find it to weigh 60.0 n, and to have an apparent weight of 56.4 n when it is completely submerged in water. take the density of gold to be 19300 kg/m^3, the density of lead to be 11340 kg/m^3, and the density of water to be 1000 kg/m^3. also, use g = 9.80 m/s^2. what percentage (by weight) of this crown is made of gold? the rest, by the way, is lead.
(a) what is the average density of the crown?
correct: your answer is correct. kg/m3
(b) what percentage (by weight) of this crown is made of gold? the rest, we assume, is lead.
incorrect: your answer is incorrect. %
