As the band passed by, the beating drums and trumpets made Billy feel like his body was beating with the music. He could hear th
e music and he could feel it! How would a scientist explain this to Billy? A) Sound waves cannot travel through the air B) Sound waves transmit energy through all forms of matter. C) The marching causes the ground to move which Billy feels D) Sound waves are transmitted faster through gases than through solids.
Answer: B) Sound waves transmit energy through all forms of matter.
Explanation: Sound waves are longitudinal waves. These transmit energy by the vibration of particles of the medium. The sound waves can travel through air, liquid and solids. The medium particles oscillate in the direction of motion of the movement of the waves.
Billy felt that his body was also beating with the music when a band of musicians passed by because sound waves can transmit energy through all kind of mediums except vacuum. The sound travels fastest in the solids than in liquids and gases as the molecules are tightly packed in a solid.
Actually, iron, cobalt, and nickel ARE all in the same group of elements. If you look on this attachment, you will see iron, nickel, and cobalt are all medals. I circled it for you.
