oops i did the wrong question(4b)

2b(i)
yes you can write that the numbers are close enough, only 0.03 ohm difference between doubled resistance of circuit 1 and circuit 2.

2(b)(ii)
-repeats
-switch circuit off between readings.

1(b)
Find center using 2 blocks on the sideslike this --->
|()|
then extend it so that the diameter is seen, put half of the cylinder to make sure the marks match and than push it farther in.(you can draw a diagram for all of this)

1d) the volume of air = length of card * width of card * 2.5mm (2-3)

     vol = 6 * 5.8 * 0.25 = 8.7cm^3

@golden girl - yes its very important

@Vin- Yes u can, with a pin, u find the 10cm mark. mark the center of the cylinder and put it on the pin.
