because they only require 6v so closing the circuit in parallel would mean that they both get 12V which is way more than what they ned and they'll burst.
can anyone tell me what they got for the damp cloth question...i said that the cloth uses the heat from the milk to evaporate the water on it...and i didnt really explain the evaporation part as there was already a question about it...

you just rearrange the equation to hald of everything u had in a but without the mass.. and make the mass the subject..
it becomes 3750
it was just 1 mark or 2 u dnt need the working for it..
and many people did the winding thing and i dont think its correct cuz they sed they wanted specifically the measurment of only one of the peices..
u cudve used calipers or a micro meter
the last question i wrote from negative to positive (aint sure)

i said connect the electric field the other way round so that the +ve is on top and the -ve is on the bottm so that the repulsion of one cancels the attraction of one
AS girl:
I dont think micrometer is right!
Micrometer is used to measure the diameter of something not the thickness of 6 plastic plates!!!
Wahab09:
they wanted to know the thickness of ONE peice of paper not 6..

By the way micrometer is absolutly fine...u just had to mention divide by 10 and my teacher said u couldve used a ruler!!! the formality of the question just confused us all
