Your college or university wishes to obtain reliable information about student perceptions of administra-tive communication. describe how to design a sam-pling plan for this situation based on your knowledge of the structure and organization of your college or university. how would you implement simple ran-dom sampling, stratified sampling, and cluster sam-pling for this study? what would be the pros and cons of using each of these methods?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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?
