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

O centroid

Step-by-step explanation:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has three medians, one from each vertex, and they all intersect each other at the triangle's centroid.
