Questions I can remember:
1. Proton , Neutron
2. The second equation can't happen -lepton number not conserved
3 X is a baryon as a to conserve baryon number
4. Specific charge was 4.79x10^7 Ckg-1
5. 6 marker on excitation of atoms
6. Ionisation is min energy required to remove electron from atom in a gaseous state
7. Internal resistance was 0.488ohms
8. Power was 0.355W
9. 5ohms was total resistance
10. Proof that resistors were 3
11. 1.33A
12. 2V
13 emf=1.52V
14. Neutrino needed to preserve lepton number
15. Electron capture
Any more?
