Question

what two factors affect the speed of a sound wave as it travels through a medium?
the energy transferred by the wave and the density of the medium
the type of medium and the energy transferred by the wave
the type of medium and the temperature of the medium
the temperature of the medium and the energy transferred by the wave

Explanation:

The speed of sound depends on the type of medium (e.g., solid, liquid, gas) as particles are arranged differently in each. Temperature also affects it as higher - temperature mediums have more energetic particles that can transmit sound waves faster. Energy transferred by the wave affects amplitude, not speed. So the correct factors are the type of medium and the temperature of the medium.

Answer:

the type of medium and the temperature of the medium
