1) 1.7mm maybe 2.7mm
b)
highest emf was 1456 or something
value of alpha was 10
100000 was the highest voltage reading
unsuitable to use because its smallest measurement was 2000 but highest reading was 1456 so the resolution was not great enough and equipment not sensitive enough
4 resistors required
power 110W (114)
Order of area 1x10^-1 maybe just be 10^0
0.51mm was the diameter
1.65x10^11 I think was young modulus
moments was 0.73Nm
MCQ:
phase differene pi/4
diffraction grating one was D
velocity was 0 and speed 2.4m/s
the refraction one was optical density
antiproton was uud all with bars above
annihiliation was p + pbar => 2 gamma phorons
Any other questions you can remember or answers please post and I'll see if I can remember the answers
