Final answer:
The frequency of the rotation of a generator is given as 79 Hz, which is also the frequency of the output voltage, unrelated to other parameters such as magnetic field, number of turns, or output voltage and current.
Step-by-step explanation:
The frequency of the rotation of a generator is simply the rate at which it spins, which is given in the problem as 79 Hz. None of the other details provided about the generator (the magnetic field, number of turns, voltage, or current) affect this frequency. Therefore, the frequency of rotation of the generator is the same as the given rotation rate.
In fact, a generator converts mechanical energy into electrical energy through electromagnetic induction. The frequency of the electricity produced is directly related to the rotational speed of the generator's coil within the magnetic field. In this case, the rotational frequency provided (79 Hz) is also the frequency of the output voltage.
