Paper 1, Paper 2 5 marks Difficulty 4

Radiation power over area

Radiation intensity in a weather balloon sensor log is \(900\,\text{W m}^{-2}\) over area \(2.7\,\text{m}^{2}\). Calculate the total power. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
