The diagram below shows the path of a comet around the Sun What is the most significant change in the comet's energy as it moves from point D to point A?

(Assume that total mechanical energy is conserved.)

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.

i believe the answer is electric potential.
