Review CAIE IGCSE Physics geometry, measurement and unit conversion through density-based volume calculations and physical-context unit handling.

How this is tested

  • calculate volume from mass and density with correct units in a physical context

Question 3(c)

[Maximum number: 2]

Fig. 3.1 shows a model of a wind turbine used to demonstrate the use of wind energy to generate electricity. The wind is blowing towards the model, as shown.

The density of air is 1.3 kg/m31.3 \mathrm{~kg} / \mathrm{m}^{3}.

Calculate the volume of air passing through the circular area swept out by the turbine blades each second.
