Madison and Oxford are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Madison compare to the air temperature of Oxford? Why?

The animation shows the circuit inside a speaker. The speaker cone vibrates as the current changes direction. This creates sound waves. Explain how the electromagnet causes movement back and forth as the electric current changes.

In a quasi-static process, the system remains infinitesimally close to equilibrium throughout the process. a) True b) False

Which of the following is required in order to make a protected left turn A. A left green arrow B. No oncoming traffic C. A left turn only lane D. A large enough gap

At steady state, a cycle develops a power output of 10 kW for heat addition at a rate of 10 kJ per cycle of operation from a source at 1500 K. Energy is rejected by heat transfer to cooling water at 300 K.

Consider a steady-state experiment in which the observed current due to reduction of Ox to R is 85 mA/cm2.
