Anybody have any answers?
I remember small questions like the one with the gears,I got that the number of turns was 8.I think the first question was nice except I forgot about the field lines so I put them in the wrong direction but it’s literally one mark.I loved the maths part of the paper,there were plenty of equation questions which was good.I remember that I put the student was incorrect because the k value kept changing.For the question on why the spray patterns are different,I said that the drops are given the same charge so they repel each other.My diagram for one of the middle questions was rubbish,but the 4 marker after that was good;I talked about the four things that affect the voltage.Hope this helps!

I think I did one about power and work done,but apart from that I don’t know lol,it was a hard hard question which confused me a lot!

I just calculated the upthrust force experienced by the block

Well i'm not sure if its right, but if the block is moving at a constant speed but the force increases when the block is being lifted out the water then we can tell that the upthrust force was helping the crane lift the block. The force the crane applied to lift the block when it was submerged in water was 102KN, and the force when the block was out of the water was 170KN (when upthrust force is no longer acting on the block). So i thought you can take away these forces the crane applied on the block to get the upthrust force. 170 - 102 = 68KN, which I think is the upthrust force experienced by the block when in the water

Ah of course. thanks. Hopefully I'l still pick up like 3 marks lol. Any idea how to calculate the weight of the block too, I guess this calculation probably isnt needed though is it?

Don't think that would be possible unless we knew the speed at which the block was being lifted at
