exam questions i have gotten wrpng Flashcards
Explain which fundemental interaction is responsable for potassium to decay into argon by electron capture realising an electron neutrino
[2 marks]
Weak interaction because it involves leptons AND hadrons
K-40 decays to form Ca-40.
Suggest how the emissions from a nucleus of decaying potassium can be used to confirm which decay process is occurring.
[3 marks]
The emission is beta minus
- electron released from nucleus
- antineutrino released
can be detected through cloud chamber
Explain why a force is required to hold nucleons together in the nucleus
2marks
Due to electrostatic repulsion between protons, the protons and neutrons would not remain stable in the nucleus hence a force is required
