Answer:
A generator
Explanation:
A generator is a machine that converts mechanical energy into electrical energy. Mostly they are used a power sources for other machines. There are various sources of mechanical energy that can be used to spin the wire coils in a magnetic field in a generator depending on the type of power plant. The wire coils have to be spined so as to induce electric potentials in the coil. it works on the principle of electromagnetic induction.
Answer:
We know that all petrol engines are works on Otto cycle.Otto cycle have four process out of four two are constant volume process and others two are isentropic processes.
There are lots of limitations for practical Otto cycle these are as follows
1.In practical cycle heat can not add at constant volume.
2.In practical cycle there is a gap between combustion of two set of fuel.
3.Lots of heat is dissipated by cylinders.
4.Valve opening and closing is not a sudden process it requires some time.
5.There is a limitations of cylinder material ,it means that temperature of cycle can not rise after a specified limit of material.
Due to these above limitations practical cycles have low efficiency as compare to ideal cycle.

Explanation:
The question is basically asking you to build a 2-bit asynchronous counter.
What the counter does is it increase it's value by 01₂ every clock pulse. So at 0₂, nothing happens, but at 1₂ it'll count up by 1. It then reset to 00₂ when it overflows.
The design for it is pretty much universal so I kinda did this from memory.
a.) A count-up counter (from 00-11) is simply made by connecting Q' to D, and the output of the previous DFF to the clock of the next one.
b.) A count-down counter (from 11-00) is simply made by using the same circuit as the count-up counter, but you connect Q' to the clock instead of Q.
