if an object producing sound is moving away from you, you would observe a wavelength than an object moving toward you. group of answer choices

Answers

If an object producing sound is moving away from us, the wavelength of the sound heard is longer than the actual wavelength. The conclusion is from the concept of Doppler effect.

What is the Doppler effect?

The Doppler's effect is a phenomenon when the source of a wave and an observer move relative to each other, the frequency heard is not the same with the actual frequency.

The equation of the Doppler effect is

f₀ = [(v ± v₀)/(v ± vs)] × fs

Where

f₀ = observer frequency of soundv = speed of sound waves (340 m/s)v₀ = observer velocityvs = source velocityfs = actual frequency of sound waves

Note:

v₀ (+) if the observer moves closer to the sound source.vs (+) if the sound source moves away from the observer.

When an object producing sound is moving away from us, the frequency of the sound we heard changed.

Let's say we are at rest, it means v₀ = 0. The sound source is moving away makes vs (+).

With the Doppler's effect, we get

f₀ = [(v+0) / (v+vs)] × fs

f₀/fs = v/(v+vs)

v < v+vs

f₀ < fs

The frequency of sound we heard is lower that the actual frequency.

The wavelength is inversely proportional to the frequency. It is described in the equation:

λ = c/f

It means that the lower the frequency, the longer the wavelength.

Hence, the phenomenon which the wavelength of the sound we heard is longer than the actual wavelength when the sound source is moving away from us is called the Doppler's effect.

Here is the group of answer choices:

(a) Band width

(b) Doppler's effect

(c) Sound refraction

(d) Vibrations

show that the probability density for the ground state solution of the one dimensional coulomb potential energy in the schrodinger equation has its maximum at x=a0

Answers

Through Schrodinger equation probability, we can prove that the probability density for the ground state solution of the one dimensional coulomb potential energy in the Schrodinger equation has its maximum at x=a₀.

Given wave function is Ψ(1s) = 1/√π{1/a₀}^(3/2) e ^(x/a₀)

Probability refers to potential.  The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means.

The Schrödinger equation is a linear partial differential equation that describes the wave function or state function of a quantum-mechanical system.

To find the most probable distance, differentiate the equation |Ψ(1s)|²x² with respect to x and equating to zero, we get

d / dr | 1/√π e(1/a₀)^3 / 2e^(-x/a₀) |² x² = 0

1 / π(1 / a₀)³ d / dr (e^-2x / e₀) (x²) = 0

[2e^(-2Zx / a₀) x + e^(-2Zx / a₀) {-2 / a₀} x²] = 0

2 + (-2 / a₀) x = 0

This gives x = a₀

Therefore, through Schrodinger equation probability, we can prove that the probability density for the ground state solution of the one dimensional coulomb potential energy in the Schrodinger equation has its maximum at x=a₀.

which of the following sequences lists methods for determining distance in the correct order from nearest to farthest?

Answers

Parallax, main-sequence fitting, cepheid variables, Tully-Fisher relation, and Hubble's law are the sequence lists methods for determining distance.

Parallax is the closest method for determining distance. This method uses the principle of triangulation to measure the distance of a nearby star relative to Earth. Main-sequence fitting is another method used to measure the distance of stars. This method compares the brightness of a star to other stars of known distance and luminosity to determine its distance.

Cepheid variables are stars whose brightness varies in a predictable way over time. This method uses the period of the star's brightness to determine its intrinsic luminosity, and then its distance. The Tully-Fisher relation is a method for measuring the distance of galaxies. This method uses the rotation speed of the galaxy and its brightness to calculate its distance.

Finally, Hubble's law is the most distant method for determining distance. This law states that the farther away a galaxy is, the faster it moves away from us. This allows us to calculate the distance of galaxies by measuring their rate of recession.

What happens to the magnetic field when the length of wire increases?

The formula  F = IL x B calculates the magnetic force acting through a magnetic field on a current-carrying wire. The magnetic field acts on a wire when a current is conducted through it in a direction that is perpendicular to both the magnetic force.

By increasing the amount of current flowing through the wire, the magnetic field's strength can be enhanced. As you get further from the wire, the strength gets weaker. If the amount of current flowing through it stays constant, its length and thickness have no bearing.

Therefore, the length of the wire in the magnetic field has an impact on the magnetic force's strength as well. The force acting on a wire increases with wire length in a magnetic field.

Calculate the internal energy of 1.2moles of steam at 177degree

Answers

Answer:

18447 J

Explanation:

To calculate the internal energy of steam at a given temperature, we need to know the specific heat capacity of steam and the enthalpy of vaporization. The specific heat capacity of steam at a constant pressure is approximately 2.08 J/g*K, and the enthalpy of vaporization (latent heat) at 100°C is 2257 kJ/kg.

We can use the following equation to calculate the internal energy of steam at a given temperature:

U = m * Cp * (T - T_b) + m * L

Where U is the internal energy, m is the mass of the steam, Cp is the specific heat capacity of steam, T is the temperature of the steam, Tb is the boiling temperature of the steam, and L is the enthalpy of vaporization.

Since we are given the amount of steam in moles (1.2 moles) and the temperature (177°C), we can convert the moles of steam to mass using the molar mass of water (18 g/mol). The boiling temperature of water at standard atmospheric pressure is 100°C, so we can use this value for Tb.

First, we need to convert the temperature from degrees Celsius to kelvins:

T = 177°C + 273 = 450 K

Then, we can calculate the mass of the steam:

m = 1.2 moles * 18 g/mol = 21.6 g

Substituting these values into the equation for internal energy, we get:

U = 21.6 g * 2.08 J/g*K * (450 K - 273 K) + 21.6 g * 2257 kJ/kg

Solving for the internal energy, we get:

U = 18,447 J

Therefore, the internal energy of 1.2 moles of steam at 177°C is approximately 18,447 J.

ω_r=1/sqrt(LC)
where ω_r is the resonant frequency in rad/s, L is the inductance in Henries, and C is the capacitance in Farads.
Given the resonant frequency of 5000 rad/s and the inductance of 10 mH, we can calculate the capacitance as follows:
C=1/(ω_r^2*L)
C=1/(5000^2*0.01)
C=4.00μF

The mass of soccer player will be 120kg.  Writing down 1/2 m1 will help us remember that KE = 1/2 mv2 (v1i) 2 + 1/2 m2(vi) (vi) 2 = 1/2 m1(v1f) (v1f) 2 + 1/2 m2 (v2f) (v2f) 2.

How to solve ?

According to Newton's third law,

Given that a soccer player runs at 10m/s and plows into a 80kg referee standing on the field causing the referee to fly forward at 56m/s. Let

mass of the player = ?

initial velocity of the player = 10m/s

Final velocity of the player

mass of the referee = 80 kg

Initial velocity of the referee = 0 ( since he is at rest )

Final velocity of the referee = 6 m/s

Since it is a perfectly elastic collision,

U1 =V2 - V1 ........ (1)

M1U1 = M2V2 + M1V1........ (2)

Substitute all the necessary parameters into the equation (1)

10 = 6 - V1

V1 = 10 - 6

V1 = 4 m/s

Now, Substitute all the necessary parameters into the equation (2)

10M1 = (80 x 6) + (4M1)

10 M1- 4 M1 = 480

4M1 = 480

M1 = 480/4

M1 = 120kg

Therefore, the mass of soccer player will be 120kg

what is the length of the y component shown below?

Answers

The length of the y component shown is C. 2.0.

How to find the length ?

We are given the angle of the vector, and the length of one of the components of the vetor. Given the angle we have, the available component is the hypotenuse. The y component that we are to find, will then be the opposite or perpendicular component.

To solve for the length of the y - component therefore, the useful operation would be the Sin function.

The length of the y - component would be:
Sin 42 ° = Opposite / Hypotenuse

Sin 42 ° = y component / Hypotenuse

y - component = Sin 42 ° x Hypotenuse

y - component = Sin 42 ° x 3

y - component = 0. 6691 x 3

y - component = 2. 0

In conclusion, the y - component is 2.0.

In the figure, a climber leans out against a vertical ice wall that has negligible friction. Distance a is 0.945 m and distance L is 1.95 m. His center of mass is distance d = 0.89 m from the feet-ground contact point. If he is on the verge of sliding, what is the coefficient of static friction between feet and ground?

Answers

The coefficient of static friction between feet and ground is 0.2522.

What is static friction?

Static friction is defined as when there is no motion between the two surfaces, the force that one surface applies to another. The friction that exists between two or more objects when they are not moving relative to one another is referred to as static friction.

The coefficient of static friction between his feet and the ground, denoted by the symbol s, determines how to express the frictional force as

fs =μsFN1

The μs can be calculated as

μs = a / √L² - a² x d / L

μs = 0.945 / √(1.95)² - (0.945)² x 0.89 / 1.95

μs = 0.945 / √2.91225 x 0.89 / 1.95

μs = 0.2522

Thus, the coefficient of static friction between feet and ground is 0.2522.

compare the time it takes for light to travel 1000 m on the surface of the earth and in outer space.

Answers

Since light is faster in space, it takes less time for light to travel a distance of 1000m, a time difference of 0.977ns.

Light travels more slowly in a transparent medium than in the vacuum of empty space. The speed of light in any medium (air, water, glass) is determined by the refractive index of the medium. However, this exponent itself may be wavelength dependent (ie different colored rays travel at different speeds). In fact, this is why a prism splits white light into the colors of the rainbow.

The main reason that a light beam slows down in a medium has to do with the fact that the photons, or 'raw light beams', are excited by an electromagnetic field. When the field is in the ground state (vacuum), these excitations actually propagate at the vacuum speed of light. However, when there are positively charged atoms and negatively charged electrons, the electromagnetic field does not go to the ground state. There are many virtual photons. Yes, some of the photons of the passing light beam can be absorbed. After all, no material is completely transparent. But even those who aren't are moving in an environment so different from the vacuum that their paths will be different. It also depends on the structure that the molecule forms.
