A second class lever is used to lift a 500 lb. load, that sits 1.328 feet from the fulcrum of a wheelbarrow. How far from the fulcrum must you stand,
in order to lift the weight with only 275 pounds? Pretend that the simple
machine is 100% efficient. (Precision of 0.00)

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?
