If you had two forces, one with a magnitude of 25 n and the other with a magnitude of 100n, what would be the maximum net force these forces could exert on an object? how would these forces have to be applied in order to exert this maximum net force?

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.
