Based on Figure 2, if an insulated wire segment
of length 6.6 cm and diameter 0.5 cm had been
tested at ΔT = 40 °C, the R value would most
likely have been:
the highest
in between the highest and the lowest.
the lowest
exactly as high as one other box.
The physics students tested an insulated wire
segment of length 6 cm at ΔT = 40 °C. Based
on Figure 3, if the students properly calculated
the R to be 89 W, the diameter of the wire
segment would most likely be in which of the
following ranges?
