Various chains were released from rest with their lower end touching a scale that measured the force, in newtons (N), of the chain on the scale pan. A newton is the force required to accelerate a 1-kilogram mass at a rate of 1.0m/s2 . The mass of the chain, its total length (L), the momentary length of the chain on the pan (x), and the momentary weight of the portion of the chain on the scale pan were also measured. The results are show in in Table 1.

In trials 5–8, as the momentary length of the chain on the pan increases, the momentary weight on the panCorrectIncorrect
Which of the following trials best supports the hypothesis that doubling the mass of the chain while keeping the mass of the weight on the pan constant doubles the force on the pan?CorrectIncorrect
Based on the data in Table 1, if a chain with a total mass of 1,250 g and a total length of 2.0 m were use, in which of the following ranges would the force on the pan be if x=1.5 m?CorrectIncorrect
Which of the following trials uses the chain with the largest mass per unit length?CorrectIncorrect
If, in trials 1–4 the entire length of the chain (0.5m) had been allowed to drop on the scale pan, the momentary weight on the pan for this new trial would have been approximatelyCorrectIncorrect
