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.

The blue mass in the image is 10kg.


The red mass in the image is 10kg.


The blue mass is currently 4 meters away from the red mass.


If we change each mass to 20kg, what will happen to the gravitational force each mass puts on the other?? You have to pick a answer through A,B,C! The force of gravity will increase as the masses increase.



The force of gravity will not change as the masses increase.



The force of gravity will decrease as the masses increase.

Amy and Chris took different routes to travel from Point A to Point E. Amy took the route along A, B, C, D, and E and reached the destination in 2 hours. Chris took the route along A, G, F, and E and reached the destination in 3 hours. Their routes are shown.



Which conclusion is correct?


Amy's average speed is twice Chris's average speed.

Chris's average speed is twice Amy's average speed.

Amy's average speed is equal to Chris's average speed.

Chris's average speed is three times Amy's average speed.
