Final answer:
The student's question involves calculating the torque factor, expressed as Nm/kg, in the context of Physics. The exact derivation of the stated torque factor of 0.3 Nm/kg is not determined from the information provided. Further clarification is needed to explain the student's specific calculation.
Step-by-step explanation:
The question relates to the concept of torque in Physics and involves the calculation of the torque factor, which is the ratio of the torque produced to the mass of the object (Nm/kg). We are given several scenarios where a torque is applied, and the moment of inertia is specified. To answer this question, we make use of the relationship T = I∗α, where T is the torque, I is the moment of inertia, and α (alpha) is the angular acceleration.
For example, if we consider an applied torque of 64.0 Nm and a moment of inertia of 4.352 kg⋅m², we can substitute these into the equation to find α. The student has mentioned a torque factor of 0.3 Nm/kg, suggesting they may have derived it by dividing a certain torque value by the mass. Without additional context or a specific procedure, it is difficult to determine how this value was derived. The details provided in the question do not include direct references to the division of torque by mass, therefore further clarification from the student would be necessary to provide an accurate and detailed explanation of their calculated torque factor.
