Hello everyone.
00:01
So here we have the five parts of a question.
00:04
So first part we'll see like first part is asking for that what is the pedal like wheel in an engine that transformed rotational motion into a mechanical energy.
00:15
So we have to tell the what is a pedal like wheel.
00:21
So pedal like wheel is we can say like that is turbine that is turbine that converts or that transform the rotational motion into a mechanical energy.
00:35
So that is the first answer.
00:37
Now moving to the second part.
00:38
Second part is asking for what is the spin? what spins the turbine in a nuclear power plant? so here is the nuclear power plant.
00:47
So in nuclear power plant we feed up the water and we generate the steam.
00:52
And that steam close to the turbine.
00:54
So here is the answer to steam.
00:57
That is d part.
01:01
This is c part.
01:03
Now moving to the third part...
