Find (a) the amplitude, (b) the wavelength, (c) the period, and (d) the speed of a wave whose displacement is given by y= 1.5 co

leonid [27]

Answer with Step-by-step explanation:

We are given that displacement of wave

$y=1.5cos(0.68x+37t)$

Where y in cm and t in sec.

a.Compare it with

$y=Acos(kx+\omega t)$

Amplitude of wave=A

We get A=1.5

Amplitude=A=1.5 cm

b.k=0.68

$\frac{2\pi}{\lambda}=0.68$

$\lambda=\frac{2\times 3.14}{0.68}=9.2 cm$

Using $\pi=3.14$

Wavelength of the wave=9.2 cm

c.Period= $\frac{2\pi}{T}=\omega$

$\frac{2\pi}{T}=37$

$T=\frac{2\times 3.14}{37}=0.17 s$

The period of the wave=0.17 s

Speed of the wave= $\nu \lambda=\frac{\lambda}{T}=\frac{9.2}{0.17}$

Speed of the wave=54.1 cm/s

By using the listing method, the number of possible uniforms that Brilliant Spa can choose from is equal to 9 uniforms.

<h3>What is a listing method?</h3>

In Mathematics, a listing method can be defined as a technique which is used to list all the elements or members of a data set, while separating each of them with a comma and enclosing the data set within curly braces.

From the information provided above, we have the following points:

Polo shirts come with color yellow, red, and green.

The pants come with color black, blue, and white.

By using the listing method, a list of all the elements in this data set is given by:

List = {(yellow, black), (yellow, blue), (yellow, white), (red, black), (red, blue), (red, white), (green, black), (green, blue), (green, white)}

Number of possible uniforms = 9 uniforms.
