A student is trying to design an artificial eardrum for their science fair project. They made their eardrum hollow to cut down on cost and weight. When they tested how long it took their test subject to hear a beep, they found that their control eardrum made out of wood did better than their created one. The temperature that day was 98°F. Determine which statement supports the student’s findings. A.
The created eardrum did not perform well because sound travels faster in solids due to the large distance between the particles.

B.
The created eardrum did not perform well because sound travels faster in solids due to the small distance between the particles.

C.
The created eardrum did not perform well because sound travels slower through the air in high temperatures due to the particles moving slower.

D.
The created eardrum did not perform well because sound travels slower in the air due to the small distance between the particles.
