Eliza starts from a house and skateboards 10 meters towards the north, then turns back and skateboards 4 meters back to the south. What is Eliza 's displacement from the house?

6m

Explanation:

If Eliza starts from a house and skateboards 10 meters towards the north, her distance will be +10m (moving towards positive y direction)

If she then turns back and skateboards 4 meters back to the south, her distance will be -4m (along the negative y direction)

The displacement from the house is 10m - 4m = 6m

it is easily magnetized.

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.
