IB Physics SL E 3 2 Binding Energy and Mass Defect Topic Practice

This question is in two parts. Part 1 is about renewable energy. Part 2 is about nuclear energy and radioactivity.

A small coastal community decides to use a wind farm consisting of five identical wind turbines to generate part of its energy. At the proposed site, the average wind speed is $8.5 \mathrm{~m} \mathrm{~s}^{-1}$ and the density of air is $1.3 \mathrm{~kg} \mathrm{~m}^{-3}$. The maximum power required from the wind farm is 0.75 MW . Each turbine has an efficiency of 30 %.

State what is meant by the binding energy of a nucleus.
