Vector vector a has x and y components of -8.60 cm and 15.0 cm, respectively; vector vector b has x and y components of 12.4 cm and -6.80 cm, respectively. if vector a - vector b + 3vector c = 0, what are the components of vector c?

Vector C will be equal to

Explanation:

It is given two vector A has x and y component as -8.65 cm and 15 cm

So vector A can be represented as

And vector B has x and y component as 12.4 cm and -6.8 cm

So vector B can be represented as

According to question

So vector C will be equal to

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.
