Maurice directs a beam of light on a sheet of glass at an angle of 51°. what is the angle of refraction in the glass? the refractive index of glass is 1.46. a. 22° b. 29° c. 32° d. 36°

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

In an experiment, how can i change human errors? be specific.
