Abrass cube, 10 cm on a side, is raised in temperature
by200c.
the coefficient of volume expansion ofbrass is
57x10-6/c.
by what percentage is anyone of the 10-cm edges increased
inlength?

Explanation:

Assuming that the thermal expansion of brass cube occurs isotropically (i.e. equal in all the directions).

Given:

Hence volume of the cube:

Now the volume of the cube after expansion:

Therefore,

Now the percentage change in the edges of the cube:

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.
