A foam cooler of negligible mass contains 1.75 kg of water. Ice from a refrigerator at -15°C, is then added to the water in the cooler. When thermal equilibrium has been
reached, the total mass of ice in the cooler is 0.778 kg. Assuming no heat exchange
with the surroundings, what mass of ice was added? For water, L- = 334 x 103 J/kg,
and for ice, g = 2100 J/(kg • K).

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.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
