What did everyone put for why the meter wasnt suitable
I got that each division would be worth 2000 μV so all of the values would lie between 0 and the first small line, so you could not take accurate enough readings... But it don't know if thats right.
seeing as no one got the same I'm guessing it was wrong, but for the zero error one I got 0.37 as it was minus 0.07😭 can someone explain it to me please

I said something along those lines and how range is not enough meaning you cant get a precise and accurate measurement but i forgot to mention 2000

If you've got a scale and it when it's closed it reads -0.07, and then when you are taking a reading it is 0.44, then the reading is how far it's moved, i.e. 0.44 - - 0.07 = 0.44 + 0.07 = 0.51mm

I don't know if you would have to mention it for the marks, but I just thought since we had just worked out the maximum value, and it said how many divisions there were, I would include it just in case.
Yo, you worked out hours, when Power is energy transferred per second. So I did divided by (365x24x60x60) but I'm not sure now. Is energy also written as kWh?
Does kWh=J or does it =kJ
I though you have to find it per second , it says kWh so 1000 x 10^3 W divided by 3600 And i got 277

how ever it could've been that when the clips were closed the student might have closed it tightly. so they said at roughly 20mm the reading was 0.2(something) so by using that it was a value of 0.4398... for the string

I think that the roughly 20mm was just to give you an example of how to read the scale. I don't think that you were supposed to use that value to calculate anything else.

Yes i said that. I said that cos of that the readings wont be precise enough and the range too large

It was kWh so i thought it was kW multipled by hours as the units said so i divided by hours ti just get kW on its own
So pissed off I forgot to add the ball's diameter to the measurement to it's surface in the moments question. I swear if error carried forward in this paper isn't nice I'm gonna do so bad.
