Problem 1: a small disk 5 mm in diameter is positioned and the center of an isothermal hemispherical enclosure aperture the disk is at 900 k, and has a diffuse gray surface with an emissivity of 0.7. the hemispherical adiabatic enclosure has a radius of r 100 mm and an emissivity 450 of 0.85. the enclosure has a small aperture of 2mm diameter. by radiative network analysis, determine the radiant power leaving the enclosure through the aperture outside the aperture the environment is at 300 k. (let the disk be surface 1, the hemispherical enclosure is surface 2, and the aperture be surface 3)

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

it is the second option.

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.
