Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.

L = 15cm = 0.15m

A = 0.15 × 0.15 = 0.0225

Sradiation is transfered from bottom

σ = 5.67 × 10⁻⁸ W/m²k

T = 605 c = 878k

Rate of energy transfer

Q = σ × A × E × T⁴

5.67 × 10⁻⁸ × 0.0225 × 2 × 0.8 × 878⁴

1792.17 W

3.2x10^7

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.
