Answer 1

The speed of sound is influenced by factors like density, elasticity, and temperature. Sound travels faster in denser, more elastic mediums and at higher temperatures.

Step-by-step explanation:

The speed of sound is affected by several factors including density, elasticity, and temperature.

I. Density: The speed of sound is inversely proportional to the density of the medium. In denser mediums, such as solids, sound travels faster compared to less dense mediums like gases.

II. Elasticity: Sound travels faster in more elastic mediums as the molecules can transmit the vibrations more easily. For example, sound travels faster in solids than in liquids or gases.

III. Temperature: The speed of sound is directly proportional to the temperature of the medium. As temperature increases, the particles move faster, leading to an increase in the speed of sound.

Based on the above information, the correct answer is option d. I, II, III, IV, and V.
