Use 4 to 5 complete sentences, explain the concepts of beats and how beats are produces.

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature. the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system. the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system. the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.

Each plate of an air-filled parallel-plate air capacitor has an area of 0.0040 m2, and the separation of the plates is 0.080 mm. an electric field of 5.3 × 106 v/m is present between the plates. what is the energy density between the plates? (ε0 = 8.85 × 10-12 c2/n · m2)
