PLEASE HELP!!!!
refer to the diagram below, which of the following is the best predictor of what would happen if the distance across section 1 in the diagram were to decrease.
a. the energy would decrease
b. the frequency would increase
c. the amplitude would decrease
d.the wavelength would increase

Answer:

B

Explanation:

As the wavelengths get closer, the frequency increases.

ex: Ultra Violet has less frequency than xray's because the distance between the waves are longer.

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.

IF YOU GET GOOD GRADES ON SCIENCE TESTS PLEASE HELP ME!!!!!
