Question
(a) What thickness of cork would have the same R-factor as a $1.0 \mathrm{cm}$ thick stagnant air pocket?(b) What thickness of tin would be required for the same R-factor?
Step 1
0 cm thick stagnant air pocket. The formula for R-factor is: R = thickness / thermal conductivity The thermal conductivity of stagnant air is approximately 0.024 W/mK. Since the thickness is given in cm, we need to convert it to meters: 1.0 cm = 0.01 m Now we Show more…

Two conductors are made of the same material and have the same length. Conductor $A$ is a solid wire of radius $1.0 \mathrm{~mm}$. Conductor $B$ is a hollow tube of outside radius $2.2 \mathrm{~mm}$ and inside radius $1.0 \mathrm{~mm}$. What is the resistance ratio $R_{A} / R_{B}$, measured between their ends?
A sheet of paper has length $27.95 \mathrm{cm},$ width 8.5 in. and thickness $0.10 \mathrm{mm}$. What is the volume of a sheet of paper in cubic meters? (Volume $=$ length $\times$ width $\times$. thickness.)
