A backsight reading of 2.56 was obtained with rod at A and a foresight reading of 7.45 was obtained with the rod at the trial point B. If B is located 37.00 feet from the center line of a planned 50-foot wide road, is the catch point located uphill or downhill from B? What would the side slope of the cut be if the catch point is located at B? Given: Elevation of A is 251.20 feet. Road bed is to be at the 240.0 foot elevation with 2:1 side slopes.

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?
