The following data were obtained in an Atwood machine experiment. Time of Fall (sec) M1 M2 R1 R2 R3 0.20 kg 0.10 kg 0.535 0.539 0.932 Distance of fall 0.455 m 1. Explain why the third reading R3 should be discarded or repeated? 2. On repeating the experiment, R3 was found to be 0.531 sec. Find the average value of the time of fall. 3. Find the value of acceleration 'a' from the above data. 4. Calculate the value of 'g' from the above data.

Answer to 5)1.96

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…
