Apotential difference of 1.47 v will be applied to a 22.6 m length of 18-gauge copper wire (diameter = 0.0400 calculate (a) the current, (b) the magnitude of the current density, (c) the magnitude of the electric field within the wire, and (d) the rate at which thermal energy will appear in the wire.

So we can now calculate the area of the wire

We need also the resistivity specific of cupper, that is:

a) We have to calculate the current that is given by,

b)

c) current density

d) Rate of thermal energy

radiation warms things up temp rises convection currents air circ windy weather

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.
