a studentistrying to design an artifical eardrum fo their science fair project. they made their eardrum hollow to cut down oncost and weight. when they tested howlong it took to test the subject tohear deep, they found that their control ear drum made outof 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.

they know that tsunamis,or ocean waves with a very large wave amplitude, happens after anther event, such as an earthquake or landslide has dramatically shifted the earths crust and therefore the water above that crust.while difficult to see the amplitude and wavelength of the individual waves while they are far out at sea, we can see how large they are as they get into shallower areas as they approach the shoreline. based on the model and explanation, how does an earthquake cause tsunamis?
A. an earthquake seismic wave provides mechanical energy to the ocean. as energy is added the amplitude of the wave is increased.
B. as the earthquake vibrates more waves are created. more waves means that there is less space between them decreasing the wavelength. because amplitude is inversely related to wavelength, this that the waves must be less energetic.
C. as the earthquake creates more waves the frequency is increased. because amplitude is directly related to frequency, the amplitude is also increased.
D. an earthquake seismic waves overlap and build upon each other as the earth continues to shake. as the earth shakes more, the amplitude of the wave increases.

A column is filled with four different liquids of different densities. A red liquid, a blue liquid, a green liquid, and a purple liquid are all added into the column. This chart shows the densities of the liquids.

A 2-column table with 4 rows titled densities of liquids. The first column titled Liquids has entries red, blue, green, purple The second column has entries 1.2 grams per centimeter cubed, 1.6 grams per centimeter cubed, 0.8 grams per centimeter cubed, 0.1 grams per centimeter cubed.

In what order would the liquids would arrange themselves, from top to bottom?

blue, red, purple, green.
purple, green, red, blue.
purple, green, blue, red.
blue, red, green, purple.
