A rectangular slab of glass with unknown index of refraction is on top of the surface of a liquid that also has an unknown index of refraction. A light beam is incident from air into the glass such that the part of the beam that strikes at the glass/liquid boundary is incident at the critical angle which is 65 degrees. The angle of incidence between the air/glass boundary is 40 degrees. Required:
a. Determine the index of refraction of the glass.
b. Determine the index of refraction of the liquid.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
