PLEASEE HELP A 30 kg wagon is accelerated across a level surface at 0.5 m/s2. What net force
caused this acceleration?

50 inches should be the resultant vector

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.

d eras and periods

i don't understand. explain it clearly
