A block of wood floats in fresh water with 0.729 of its volume V submerged and in oil with 0.942 V submerged. Find the density of (a) the wood and (b) the oil.

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.

neither accurate nor precise.

it is a negative acceleration
