Explanation:
I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
Surface area is 1.10 × 10^-5 .
Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature.All bodies radiate energy W depending on temperature T, according to the Stefan-Boltzmann law W = ε σT4 where emissivity ε is equal to 1 for black bodies and less than 1 for grey bodies, σ being the Stefan constant.
From Stefan's law, the power radiated by an object at absolute
temperature T and surface area A is POAT, where a=5.6696 × 10
W/m²K and e is the emissivity. Thus, the surface area of the filament
must be
A =75 W / (5.6696x10 )(1.0 )(3300) = 1.10 * 10^-5
