The graph shows how binding energy per nucleon varies with nucleon number for atomic nuclei. The arrows w, x, y and z represent changes in binding energy per nucleon and nucleon number.
Fission and fusion of nuclei may result in the release of energy.
Which row of the table gives the arrows representing energy release by fission
The diagram shows binding energy per nucleon against nucleon number for atomic nuclei.
Which line of the table correctly identifies the process that would increase stability for nuclei in the positions indicated by X and Y?

Nuclear fusion involves small nuclei joining to make larger nuclei. Nuclear fission involves large nuclei splitting to become smaller nuclei. Both of these processes release energy.
The graph shows how the binding energy per nucleon varies with nucleon number for a range of isotopes.
Use the binding energy per nucleon curve to explain how fusion and fission both release energy.
Explain the conditions required to bring about and maintain nuclear fusion.

Laugh now. Cry in the exam hall later. Then come back and do a past paper.

how's physics going sweetie?? 🥰
revising forces and motion rn
come and set the table 💖
