Final answer:
The SI unit for cycles per second is the hertz (Hz).
Step-by-step explanation:
The SI unit for cycles per second is the hertz (Hz). The hertz is the unit of frequency and is used to measure the number of cycles or oscillations of a periodic wave that occur in one second. One hertz is equivalent to one cycle per second.
The SI unit for cycles per second is the hertz (Hz). It is represented as 1/s and is used to measure frequency. For example, if an event repeats itself 10 times in one second, its frequency would be 10 Hz.
