Transcribed Image Text:Question 26 Out of curiosity, a physics student checks the mass of their favorite chocolate bar, the Newton bar, and compares it to its biggest rival, the Hooke bar. The student notes that both bars should have the same mass since the values stamped on the wrappers by the manufacturers are the same, which are both 80.0 0.2 g. Using a digital scale in one of the physics labs, the student weighed 10 chocolate bars for each brand, and averaged the results for both and recorded the results in their notebook as: the Newton bar: (79.6 ± 0.2) g the Hooke bar: (79.7 ± 0.1) g Which of the following statements best describes the comparison between the two different chocolate bars masses, as well as the stamped value? O There is not enough information given to compare the two chocolate bars with each other, or the stamped value. There is not enough information given to compare the two chocolate bars with each other but they can be compared to the stamped value on the wrappers. ) The values for the two bars agree with each other, and the stamped value. O Clearly, the digital scale the student used was not working correctly, throwing off the results, thus we can not compare the answer of the bars nor with their stamped value. O The values for the two bars agrees with each other, but neither bar agrees with the stamped value. ) The student clearly did something wrong since they did not get the same results as was stamped on the wrapper, thus they should redo the experiment to get the correct value for the mass.
