Describe the direction of the acceleration and velocity vectors at point A and B

I don't have the answer, try scanning it to see if anyone else answered it.

la última respuesta, tanto a   y c.

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.
