Sally works as an estimator for G&J Electric. She has determined that 550 Feet electrical cable will be needed to wire a new house. Later, Sally is told that the homeowner has decided to cut back from a three-car garage to a two car garage, which will eliminate two branch circuits, one of 23 feet, and the other of 34 feet. How many feet of wire will be needed now?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
