### Step-by-Step Solution: 1. **Understanding the Coolidge Tube Experiment**: The Coolidge tube is an X-ray tube where electrons are emitted from a heated filament and accelerated towards a target material. When these high-energy electrons collide with the target, they produce X-rays. 2. **Electron Emission**: When the filament is heated, it emits electrons due to thermionic emission. These electrons are then accelerated towards the target material by the potential difference (V) applied across the tube. 3. **Energy Transfer**: Upon striking the target material, the kinetic energy of the electrons is transformed into different forms of energy. Approximately 99% of this energy is converted into heat, while about 1% is converted into X-rays. ...
