Question

2 what do the sound waves from a lions roar and a mouses squeak have in common? a speed b volume c frequency d amplitude

Explanation:

Sound waves' speed in a given medium (like air) is constant, regardless of the source (lion's roar or mouse's squeak). Volume relates to amplitude (loudness), and lion's roar vs. mouse's squeak differ in volume (amplitude) and likely frequency. So their commonality is speed in the same medium.

Answer:

A. Speed
