Problem 11CQ In very humid climates where there are numerous bodies of water, such as in Florida, it is unusual for temperatures to rise above about 35C(95F) . In deserts, however, temperatures can rise far above this. Explain how the evaporation of water helps limit high temperatures in humid clim

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
