Question

which factors affect the speed of sound?
type and volume of medium
temperature and type of medium
volume and temperature of medium

Explanation:

To determine the factors affecting the speed of sound, we recall the physics principles: The speed of sound depends on the type of medium (e.g., solid, liquid, gas) and the temperature of the medium. Volume of the medium does not affect the speed of sound. So the correct option is the one with temperature and type of medium.

Answer:

B. temperature and type of medium (assuming the second option is labeled B; if not, the option "temperature and type of medium")
