Solution

A J-K flip-flop with J = 1 and K = 1 is in toggle mode. This means that the output will change state every time there is a clock pulse. Given that the clock input is 20 kHz, the output will be a square wave with half the frequency of the clock input. Therefore, the Q output is a 10 kHz square wave.
