Atraveler first drives 18.6 km east, then 30.3 km southeast, and finally 10.7 km south. find the traveler's total displacement ?

i believe it is b. what was the cause of the big bang

hope this !

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.
