In the construction industry why are i beams generally used as support as opposed to solid rectangular beams?

i don't know that i agree with that but what's the question ?

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.

we need to know the time interval during which the force acts. impulse of force = momentum change
