The frequency of the human ear canal is 2.92 kHz.
Explanation:
As the ear canal is like a tube with open at one end, the wavelength of sound passing through this tube will propagate 4 times its length of the tube. So wavelength of the sound wave will be equal to four times the length of the tube. Then the frequency can be easily determined by finding the ratio of velocity of sound to wavelength. As the velocity of sound is given as 339 m/s, then the wavelength of the sound wave propagating through the ear canal is
Wavelength=4*Length of the ear canal
As length of the ear canal is given as 2.9 cm, it should be converted into meter as follows:

Then the frequency is determined as
f=c/λ=339/0.116=2922 Hz=2.92 kHz.
So, the frequency of the human ear canal is 2.92 kHz.
Velocity, unlike speed, includes a direction.
Velocity is a vector quantity which is defined by magnitude and direction.
Speed is a scalar quantity. It is the rate at which an object moves regardless of which direction.
The plate that is covering most of the two continents
is the Eurasian plate.
The continents are
<span><span>
1. </span><span> Europe</span></span>
<span><span>
2. </span><span> Asia</span></span>
The Eurasian plate is a tectonic plate that amasses
the whole continent of what others call as “Eruasia”.
It takes part of the oceanic crust that starts from
the Mid-Atlantic Ridge and extends itself to northward of the Gakkel Ridge. The
size of this plate is for about 67,800,000 km according to statistics and
geography.
When 6210 bucks is converted to kilobucks, the result obtained is 6.21 kilobucks
<h3>Conversion scale </h3>
1000 bucks = 1 Kilobuck
Using the above convesion scale, we can express 6210 bucks in kilobucks
<h3>How to express bucks in kilobucks</h3>
1000 bucks = 1 Kilobuck
Therefore,
6210 bucks = (6210 × 1) / 1000
6210 bucks = 6.21 kilobucks
Thus, 6210 bucks is equivalent to 6.21 kilobucks
