An Introduction to Thermal Physics 1
Problem 13P Use a Maxwell relation from the previous problem 1 and the third law of thermodynamics to prove that the thermal expansion coefficient ? (defined in Problem 2) must be zero at T = 0. Problem 1: Functions encountered in physics are generally well enough behaved that their mixed partial d

Sears and Zemansky's University Physics with Modern Physics 13
Problem 62E Two rods, one made of brass and the other made of copper, are joined end to end. The length of the brass section is 0.300 m and the length of the copper section is 0.800 m. Each segment has cross-sectional area 0.00500 m2. The free end of the brass segment is in boiling water and the fr

A physical pendulum consists of an 85-cm-long, 240-g-mass, uniform wooden rod hung from a nail near one end (Fig. 14-38). The motion is damped because of friction in the pivot; the damping force is approximately t proportional to d6/dt. The rod is set in oscillation by displacing it 15 from its equil

Krugman's Economics for AP® (High School) 2
A country can produce either 100 bushels of wheat or 150 units of textiles, as shown on the graph above. If an advance in technology affects only the production of textiles, what happens to the slope of the production possibilities curve and the opportunity cost of wheat? Slope Opportunity cost of wh
