Question: King Hero ordered a new crown to be made from pure gold ( density = 1 9 2 0 0 k g m 3 )

King Hero ordered a new crown to be made from pure gold

(

density

= 19200 k \frac{g}{m} 3) .

When he received the crown he suspected that other metals may have been used in the construction. Archimedes discovered that the crown needed a force of

20.91

N to suspend when submersed in water and that it displaced

3.1 10 - 4 m 3

of water. He concluded that the crown could not be pure gold. Do you agree or disagree?
