I just discovered a 3.5 MSun main-sequence star orbiting a 2.5 MSun red giant. I'll bet that red giant was more massive than 2.5 MSun when it was a main-sequence star. Part A Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false) and choose the correct explanation. Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false) and choose the correct explanation. This statement is sensible. The 2.5MSun red giant had to be more massive than its companion at some point in the past in order for it to be more advanced in its evolutionary state than its companion. This statement does not make sense.

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

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)
