In the old west, a cowboy would put their ear on the railroad track to determine if a train was coming. Using this method, they could tell if the train was coming sooner than just listening for the train. A good explanation for this would be that A) sound and vibrations travel faster through gases than solids. B) sound and vibrations travel faster through solids than gases. C) sound and vibrations dissipate faster in solids than in liquids or gases. D) sound and vibrations are more concentrated in solids than in liquids or gases.

The cowboy could tell if the train was coming sooner than just listening for the train because sound and vibrations travel faster through solids than gases.

What is the speed of sound?

Speed of sound is the rate by which the sound wave travels. The speed of sound depends on the medium by which the sound wave is travelling.

In air, the speed of sound in dry air at 20 degree Celsius is equal to the 343 m/s. The speed by which the sound is travel is more in solid than the gases.

In the old west, a cowboy would put their ear to the railroad track to determine if a train was coming.

Using this method, they could tell if the train was coming sooner than just listening for the train.

Let's check all the options.

A) sound and vibrations travel faster through gases than solids.
B) sound and vibrations travel faster through solids than gases.
C) sound and vibrations dissipate faster in solids than in liquids or gases.
D) sound and vibrations are more concentrated in solids than in liquids or gases.

As the speed by which the sound is travel is more in solid than the gases. Thus, the option B is correct.

Hence, the cowboy could tell if the train was coming sooner than just listening for the train because sound and vibrations travel faster through solids than gases.
