The wave function for a traveling wave on a taut string is (in SI units)
weqwewe [10]
  1. The speed of travel of this wave is 3.333 m/s and the direction of the wave is in the positive direction (+x).
  2. The vertical position of an element of the string at t = 0, x = 0.100 m is equal to 5.5 meters.
  3. The wavelength of this traveling wave is equal to 0.667 meter.
  4. The frequency of this traveling wave is equal to 5 Hertz.
  5. The maximum transverse speed of any element of this string is equal to 11.0 m/s.

<h3>How to determine the speed and direction of travel of the wave? </h3>

Since the wave function for this traveling wave on a taut string is (in SI units) is given by y(x,t) = 0.350sin(10πt - 3πx + π/4). Thus, we can logically deduce that the wavelength and angular wave number are as follows:

Wavelength, ω = 10π rad/s.

Angular wave number, k = 3π rad/m.

Now, we can calculate the speed of travel of this wave:

Speed, v = ω/k

Speed, v = 10π/3π

Speed, v = 3.333 m/s.

Based on the wave function, we can logically deduce that the direction of the wave is in the positive direction (+x).

<h3>How to determine the vertical position of an element of the string?</h3>

The vertical position of an element of the string at t = 0, x = 0.100 m is given by:

y(x, t) = 0.350sin(10πt - 3πx + π/4)

y(0.100, 0) = 0.350sin(10π(0) - 3π(0.100) + π/4)

y(0.100, 0) = 0.350sin(-0.157)

y(0.100, 0) = 0.055 cm × 100 = 5.5 meters.

<h3>How to determine the wavelength?</h3>

Mathematically, the wavelength of a traveling wave is given by this formula:

ω = 2π/k

ω = 2π/3π

Wavelength, ω = 0.667 meter.

<h3>How to determine the frequency?</h3>

Mathematically, the frequency of a traveling wave is given by this formula:

Frequency, f = ω/2π

Frequency, f = 10π/2π

Frequency, f = 5 Hertz.

<h3>What is the maximum transverse speed of an element of this string? </h3>

Mathematically, the maximum transverse speed of any element of this string can be calculated by using this formula:

Vmax = ωA = 2πfA

Vmax = 10 × 3.142 × 0.350

Vmax = 10.997 ≈ 11.0 m/s.

A wave has a frequency of 15,500 Hz and a wavelength of 0.20 m. What is the
Hoochie [10]

Answer:

3100 m/s

Explanation:

The relationship between frequency and wavelength of a wave is given by the wave equation:

v=f\lambda

where

v is the speed of the wave

f is its frequency

\lambda is the wavelength

For the wave in this problem,

f = 15,500 Hz

\lambda=0.20 m

Therefore, the wave speed is

v=(15500)(0.20)=3100 m/s

A 1,70 atm, una muestra de gas ocupa 4,25 litros. Si la presión en el gas aumenta a 2.40 atm, ¿cuál será el nuevo volumen?
statuscvo [17]

At 1.70 atm, a gas sample occupies 4.25 liters. If the pressure in the gas increases to 2.40 atm, what will the new volume be?

Answer:

3.01L

Explanation:

Given parameters:

Initial pressure, P1  = 1.7atm

Initial volume, V1  = 4.25L

Final pressure, P2  = 2.4atm

Unknown:

Final or new volume, V2  = ?

Solution:

To solve this problem, we use Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".

            P1 V1  = P2 V2

P1 is the initial pressure

V1 is the initial volume

P2 final pressure

V2 final volume

        1.7 x 4.25  = 2.4 x V2

             V2  = 3.01L
