I got that too! What should the answer have been?
I got it aswell!
The Moment question ranges between 0.725 and 0.760. My teacher did this problem and he told us this was the answer

A lot of people around me said 2.7mm. I spent the whole night learning how to read a caliper so if I really did get it wrong I'll be really angry lol
Did you get 1.7?

for the number of components did anyone get 4?
At first i somehow got somewhere in the thousands, but after a little recalculation i got 4 as well.

I dont know if thats right but i put that aswell
I think it was lambda divided by 4. Because an alpha particle has 4 times the mass, so lambda = p/mv. Timesing mass by 4 makes lambda 4 times smaller.

The answer was 5 since if the number of resistors was 4 the wattage will exceed 100W so it had to be 5 since the resistance will therefore decrease... only one mark will be lost for stating 4 though.
If it had to be five rather than four then why couldn't there be an even greater number of resistors (i.e. 6 or 7 - this would surely cause total resistance to decrease even further??)
