Gold

Mixture

Explanation:

Density

The density of an object of mass m and volume V is given by:

We are given the following densities:

Gold: 19.3 gr/cm3

Silver: 10.5 gr/cm3

With the data provided in the table, we can confirm which of the three columns corresponds to gold, silver, or a mix of both.

Calculating the first density: m1=1,930 gr, V1=100 cm3

This crown is made of gold

Calculating the second density: m2=1,930 gr, V2=184 cm3

This crown is made of silver

Calculating the last density: m3=1,930 gr, V3=150 cm3

Since the value of the density is between gold and silver, this crown is a mixture.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
