User: The function of the eardrum is to
• A. vibrate with the frequency of the received sound.
• B. collect the sound waves.
• C. carry the sound energy to the brain.
• D. amplify the received sound.
Weegy: The function of the eardrum in the middle ear is to vibrate with the frequency of the received sound.
User: If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?
Weegy: If a wave has a wavelength of 9 meters and a period of 0.006, the velocity of the wave is 1500 m/s.
Solution:
9 / 0.006 = 1500.
User: A wave with a period of second has a frequency of
• A. 300 Hz.
• B. 3 Hz.
C. 33 Hz.
D. 67 Hz.
Weegy: A wave with a period of 1/3 second has a frequency of 3 Hz.
f = 1/T = 1/(1/3) = 3
User: What part of the human ear contains the eardrum?
Weegy: The "middle ear" contains the eardrum.
