A transverse mechanical wave is traveling along a string lying along the x-axis. The displacement of the string as a function of

kvv77 [185]

The wavelength of the wave is 1.16m and the velocity is 23.64m/s.

To find the answer, we have to know more about the Transverse waves.

<h3>How to find different parameters of a wave?</h3>

The displacement of the string as a function of position and time, y(x,t), when the wave traveling along a string lying along the x-axis is given as,

$y(x,t)=0.048sin(5.40x-128t)$

Comparing this with the general form of wave equation, we get,

$amplitude, a=0.048m\\wave vector, k=5.40\\angular frequency,w=128Hz$

We have to find the wavelength of the wave, for this, we have the expression as,

$k=\frac{2\pi }{wavelength} \\\\wavelength=\frac{2\pi }{k} =\frac{2*3.14}{5.40} \\\\wavelength=1.16m$

We have to find the velocity of the wave,

$v=frequency*wavelength\\2\pi f=w, thus,\\f=\frac{w}{2\pi } =\frac{128}{2*3.14}=20.38s^{-1}\\\\v=1.16*20.38=23.64m/s$

Thus, we can conclude that, the wavelength of the wave is 1.16m and the velocity is 23.64m/s

A car starts from rest with an acceleration of 5 ft/s. What is its velocity after it has gone 600 ft?

Soloha48 [4]

Answer:

First, let’s correct the question. Acceleration is the rate of change in velocity. Its unit therefore is ft/sec/sec. If S is the distance traveled for a given duration, S = Vot + (1/2)at^2 where Vo is the initial velocity, a is the acceleration and t is the time. For Vo = 0, a = 6m/sec/sec and t = 3 sec. The distance traveled is S = 0 + (1/2) x 6 x 3^2 = 27 meters

Snorkeling by humans and elephants. When a person snorkels, the lungs are connected directly to the atmosphere through the snork

fgiga [73]

Answer:

2354.4 Pa

40221 Pa

Explanation:

$\rho$ = Density = 1000 kg/m³

g = Acceleration due to gravity = 9.81 m/s²

h = Depth

The pressure difference would be

$\Delta P=\rho gh\\\Rightarrow \Delta P=1000\times 0.24\times 9.81\\\Rightarrow \Delta P=2354.4\ Pa$

The pressure difference in the first case is 2354.4 Pa

$\Delta P=\rho gh\\\Rightarrow \Delta P=1000\times 4.1\times 9.81\\\Rightarrow \Delta P=40221\ Pa$

The pressure difference in the second case is 40221 Pa
