Planet z has diameter 1.8 × 107 m. on the planet's surface, the acceleration due to gravity is 19.5 m/s2. what is the mass of the planet? note: the constant of universal gravity (g) equals 6.674 × 10-11 n ⋅ m2/kg2.

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.
