To solve this problem it is necessary to apply the concepts related to frequency, wavelength and speed of sound.
The frequency is defined as,
Where,
Speed of sound
Calculating the values of the frequencies with the two wavelengths we have
And,
Therefore the frequency of the beat is
Finally we can get the wavelenght through the same equation, then
We can conclude that the frequency of the beats these musicians hear when they play together is 3.22 Hz and the out of tune guitarists should tighten his guitar string to correctly tune it.
According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.
Hope this helps.
Explanation:
It is given that,
Mass of the car 1,
Initial speed of car 1, (east)
Mass of the car 2,
Initial speed of car 2, (north)
(b) As the cars stick together. It is a case of inelastic collision. Let V is the common speed after the collision. Using the conservation of momentum as :
The magnitude of speed,
V = 12.22 m/s
(b) Let is the direction the wreckage move just after the collision. It is given by :
Hence, this is the required solution.
