In Part 1 of the lab activity, you did not assume that the center of mass was at the 50 cm mark. Instead, you determined the location of the center of mass of the meter stick to eliminate this source of error. Let's say that the actual center of mass is at the 49 cm mark. If you did not measure this and assumed it was at 50 cm, what kind of error would have been introduced

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)

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?
