Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the speed of sound in a gas with a bulk modulus of 1.4 × 10⁵ Pa and density of 1.2 kg/m³.

💡 Hint: Use the speed of sound formula directly.

Challenge 2 Hard

If the speed of sound in a particular metal is 5000 m/s, and the density is 8000 kg/m³, what is its bulk modulus?

💡 Hint: Remember to square the speed before multiplying by density.
