a studentistrying 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 to test the subject to hear deep, they found that their control ear drum made out of wood did better than their created one. the temperature that day wa 98 fahrenheit.
determine which statement supports the students findings.
a. the created eardrum performed worst because sound travels faster in solids due to large distance between the particals
b. the created eardrum performed worst because sound travels faster in solids due to the small distance between the particles.
c. the created eardrum performed worst because sound travels slower in air due to the small distance between the particles.
d. the created eardrum performed worst because sound travels slower through air in high temperatures due to the particles moving slower.
