Which part of the ear receives the signal from the eardrum?​
Aleksandr [31]

Answer:

Ossicles

Explanation:

Sound causes eardrums to vibrate. These vibrations are then passed on to the ossicles, which is made up of 3 small bones-- the malleus, incus, and stapes. The stapes are connected to the inner ear, specifically to the cochlea which transforms sound waves into electrical signals that are sent to the brain.

Which wave characteristics is defined as the number of cycles of a periodic wave occurring per unit time?
Assoli18 [71]
<h3><u>Answer;</u></h3>

Frequency

<h3><u>Explanation;</u></h3>
  • <em><u>Waves are disturbances that travel through a material medium. There are several characteristics of waves, which includes; wavelength, frequency, period and amplitude. </u></em>
  • Amplitude is the maximum displacement of wave particles, or simply the height of the wave, measured in meters.
  • Wavelength is the distance between adjacent crests or troughs in a transverse wave or between two successive rarefaction or compressions in a longitudinal wave, measured in meters.
  • Period is the time it takes for one complete wave to pass a given point, measured in seconds.
  • <em><u>Frequency is the number of complete waves or cycles that pass a point in one second, measured is inverse seconds, or Hertz (Hz).</u></em>

An object traveling at a constant speed but with a changing direction is accelerating.
prohojiy [21]

Strange as it may seem, that's true. (choice 'a'.)

"Acceleration" doesn't mean "speeding up".  It means ANY change in
the speed or direction of motion.  So a car with the brakes applied
and slowing down, and a point on the rim of a bicycle wheel that's
turning at a constant rate, are both accelerating.
