A series RCL circuit has a resonant frequency of 2200 Hz. When operating at a frequency other than 2200 Hz, the circuit has acapacitive reactance of 5.50 Ohms and an inductive reactanceof 35.0 Ohms. What are the values of (a) L and(b) C? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.
A system receives 107 joules in the form of heat energy in a specified process and it produces work of 4*10^6 joules. The system velocity changes from 10km/s to 25 km/s and its elevation changes from 20m to 12m. The mass of the system is 50 kg. Deter..
