You have four 35-ton, off-highway trucks hauling from apit to an airfield job. The haul road is maintained by a patrolgrader and has a rolling resistance of 80 lb/ton. The road isessentially level and the distance one-way is 2.1 miles. Thegross weight of the truck when loaded is 70 ton

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?
