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 wav

Explanation:

Sound, which is a mechanical wave, travels faster in solids than in liquids or gases. This is because the speed of the mechanical waves is determined by a relationship between the elastic properties of the medium in which they are propagated and the mass per unit volume of the medium (that is: density).  

In other words: The speed of sound varies depending on the medium through which the sound waves travel.  

In addition, it varies with changes in the temperature of the medium. This is because an increase in temperature means that the frequency of interactions between the particles that transport the vibration increases, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.  

For example, the higher the air temperature, the greater the velocity of propagation.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
