Asolid sphere has a temperature of 614 k. the sphere is melted down and recast into a cube that has the same emissivity and emits the same radiant power as the sphere. what is the cube's temperature in kelvins?

581.87 K

Explanation:

Given

Sphere is melted to form a square

Let the radius of sphere be r and square has a side a

Therefore

Surface area of sphere

Surface area of cube

Total emmisive remains same

Thus

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.
