In air, a sound wave with a frequency of 196 hz has a wavelength of about 1.76 meters. what is the wavelength of a wave if the f

Aloiza [94]

The wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

Given the data in the question;

Frequency of sound wave a; $f_a = 196Hz = 196s^{-1}$

Wavelength of sound wave a; $\lambda _a = 1.76m$

Speed of sound wave; $v =\ ?$

Frequency of sound wave b; $f_b = 784Hz = 784s^{-1}$

Wavelength of sound wave b; $\lambda _b = ?$

<h3>Wavelength</h3>

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

$\lambda = \frac{v}{f}$

Where v is velocity and f is frequency.

First, we calculate the velocity of the sound wave in air from sound wave a.

$\lambda = \frac{v}{f}\\ \\1.76m= \frac{v}{196s^{-1}}\\\\v = 1.76m * 196s^{-1}\\\\v = 344.96m/s$

Now, we determine the wavelength of sound wave b using the velocity of sound wave in air calculated above.

$\lambda = \frac{v}{f}\\ \\\lambda = \frac{344.96m/s}{784s^{-1}}\\\\\lambda = 0.44m$

Therefore, the wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

A current trend is for employers to require _______ and ______ to establish job eligibility.

snow_tiger [21]

Answer:

b) job experiences; degrees

Explanation:

In recent times, the employers tend to require job experience and degrees from the people that apply for jobs. The reason for this is that the economy is extremely competitive, so the employers try to get people that are already qualified for the job, will not need training for it, and that can contribute directly. While this is good for the companies and their economic interests, it is actually very bad for the young people that try to find job, as they are required to have experience, but rarely who employs them so that they can gain that experience, sot he percentage of unemployed young people is on the rise unfortunately.
