Could someone please remind me of the relay question, I attempted the last question but did not see anything related to reed switches or relays.
i did the diagram of a relay, i 4gt the question too but there was no mention of reed switch, just "draw the diagram of a relay and explain how it can be used to switch on the motor"
even i wrote pretty much the same thing about the pressure question, the molecules had to apply a bigger force per unit area to counteract the bigger pressure due to the depth

But there was no motor part on the last question. I did the question where we had to predict the direction of the wire PQ.

The motor question was the last question is section B. did you do paper 21 or 22?
