Two concrete spans of a 290 m long bridge are placed end to end so that no room is allowed for expansion. 290 m T T + 20◦C y If the temperature increases by 20◦C, what is the height to which the spans rise when they buckle? Assume the thermal coefficient of expansion is 1.2 × 10−5 ( ◦C)−1 . Answer in units of m.

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.
