Piano tuners use frequency differences and beat frequencies to tune pianos.

(a) The frequency of the third harmonic of A can be calculated by multiplying the fundamental frequency of A (440 Hz) by 3, resulting in a frequency of 1320 Hz. The frequency of the second harmonic of E can be calculated by multiplying the fundamental frequency of E (659 Hz) by 2, which is 1318 Hz. To find the frequency difference between the two, subtract the second harmonic of E from the third harmonic of A: 1320 Hz - 1318 Hz = 2 Hz.

(b) When the tuner strikes the A and E strings simultaneously, she listens for beats between the harmonics. The beat frequency indicates that the E string is properly tuned. The beat frequency is equal to the difference between the frequencies of the harmonics. In this case, the beat frequency would be 2 Hz.

(c) When the tuner hears four beats per second, it means there is a beat frequency of 4 Hz between the harmonics. To find the frequency of the E string, we can use the formula: Beat Frequency = Frequency of Higher Harmonic - Frequency of Lower Harmonic. Rearranging the formula, we get: Frequency of Higher Harmonic = Beat Frequency + Frequency of Lower Harmonic. Plugging in the values, we get: Frequency of Higher Harmonic = 4 Hz + 659 Hz = 663 Hz.

Opaque materials absorb all the light that shines on them.  None of it comes out the other side.  That's why they're opaque.

Opaque materials become warmer when light shines on them, because they absorb the energy carried by the light that shines on them.  (According to the law of Conservation of Energy, that energy has gotta go somewhere.)

Opaque materials become warmer when light shines on them due to the absorption of light energy by the atoms and molecules of the material.

Opaque materials become warmer when light shines on them due to the absorption of light energy. When light hits an opaque material, the photons from the light wave interact with the atoms and molecules of the material. These interactions cause the atoms and molecules to vibrate, generating heat energy and resulting in an increase in temperature.

For example, when sunlight shines on a black, opaque surface, the surface absorbs most of the light energy. The absorbed energy causes the atoms and molecules of the surface to vibrate, leading to an increase in temperature.

In contrast, transparent materials, such as glass, allow light to pass through them without significant absorption. As a result, they do not become as warm when light shines on them.

Explanation:

50/4 + 74/2

If a train travels 50 kilometers in 4 hours, and then 74 kilometers in 2 hours its average speed is 24.75 km / hr.

Explanation:

Speed is related to the ratio of distance and time. Speed = Distance / time.

Speed of the first train = 50 / 4 = 12.5 km / hr

Speed of the second train = 74 / 2 = 3 7 km / hr

Average speed = (12.5 + 3 7 ) / 2 = 24.75 km / hr

So the average speed of the train is 24.75 km / hr.

The photoelectric effect consists of the emission of electrons (electric current) that occurs when light falls on a metal surface under certain conditions.

If the light is a stream of photons and each of them has energy, this energy is able to pull an electron out of the crystalline lattice of the metal and communicate, in addition, a kinetic energy.

This is what Einstein proposed:  

Light behaves like a stream of particles called photons with an energy

[tex]E=h.f[/tex]  (1)

So, the energy [tex]E[/tex] of the incident photon must be equal to the sum of the Work function [tex]\Phi[/tex] of the metal and the kinetic energy [tex]K[/tex] of the photoelectron:

[tex]E=\Phi+K[/tex]  (2)

Where [tex]\Phi[/tex] is the minimum amount of energy required to induce the photoemission of electrons from the surface of a metal, and its value depends on the metal.

In the case of Copper [tex]\Phi=4.7eV[/tex]

Now, applying equation (2) in this problem:

[tex]E=4.7eV+1.10eV[/tex]  (3)

[tex]E=5.8eV[/tex]  (4)

Now, substituting (1) in (4):

[tex]h.f=5.8eV[/tex]  (5)

Where:

[tex]h=4.136(10)^{-15}eV.s[/tex] is the Planck constant  

[tex]f[/tex] is the frequency  

Now, the frequency has an inverse relation with the wavelength [tex]\lambda[/tex]:  

[tex]f=\frac{c}{\lambda}[/tex] (6)  

Where [tex]c=3(10)^{8}m/s[/tex] is the speed of light in vacuum  

Substituting (6) in (5):

[tex]\frac{hc}{\lambda}=5.8eV[/tex]   (7)

Then finding [tex]\lambda[/tex]:  

[tex]\lambda=\frac{hc}{5.8eV } [/tex]   (8)

[tex]\lambda=\frac{(4.136(10)^{-15} eV.s)(3(10)^{8}m/s)}{5.8eV }[/tex]    

We finally obtain the wavelength:

[tex]\lambda=213^{-9}m=213nm[/tex]    

In this example of the photoelectric effect, the maximum kinetic energy of ejected electrons from a copper surface is given. By using this kinetic energy, Planck's constant, and the work function energy for copper, a calculation can be made to determine the frequency of the incident light. From that frequency, another calculation can determine the corresponding wavelength of the light.

This question relates to the photoelectric effect in physics. In essence, the photoelectric effect is a process where electrons are ejected from a material when electromagnetic (EM) radiation is incident on it. The process is explained by the energy of photons, which are quanta of EM radiation, interacting with individual electrons.

A key equation in understanding this interaction is E = hf, where E is the energy of the photons, h is Planck's constant, and f is the frequency of the radiation. Now, the maximum kinetic energy (KEmax) of the ejected electrons is given by, KEmax = hf - BE, where BE represents the binding energy or work function of the electron to the copper surface.

Given that the maximum kinetic energy KEmax is 1.10 eV (electron-volts), and knowing that Planck's constant h is approximately 4.136 x 10^-15 eV/s, we can rearrange the equation to solve for the frequency f -> f = (KEmax + BE) / h. We need the work function or binding energy BE for copper, which is typically around 4.7 eV. Plug all the values into the equation to get the frequency f.

Furthermore, frequency f and wavelength λ are related by the equation c = fλ, where c is the speed of light (~3.0 x 10^8 m/s). Rearranging that equation for λ -> λ = c / f provides the setup to solve for the wavelength of the light used in the photoelectric effect experiment with copper.

Final answer:

Isotopes of an element differ in the number of neutrons they have but have the same number of protons. Answer B) neutrons, protons, is correct for the given question on the nature of isotopes.

Explanation:

An element may have several isotopes that contain different numbers of neutrons but the same number of protons. The correct answer to the question is B) neutrons, protons.

Isotopes are variants of a particular chemical element, which while having the same number of protons, differ in the number of neutrons they possess. Thus, isotopes of an element have identical atomic numbers (representing the number of protons) but different mass numbers (representing the total number of protons and neutrons). This variation in the number of neutrons does not affect the chemical properties of an element, as these properties are primarily determined by the number of protons and electrons, which are the same in all isotopes of an element.

Final answer:

A battery stores electrical energy via chemical reactions that release electrical energy to move electrons in a circuit when connected.

Explanation:

The most accurate description of how a battery stores electrical energy is through chemical reactions that occur within it when placed in a circuit. These chemical reactions convert chemical potential energy into electrical energy, which is then utilized to move electrons throughout the circuit.

This process increases the potential energy of the electrons, allowing them to do work, such as lighting a bulb or powering a motor. It is important to note that in electrochemical cells, or batteries, electrical energy is generated as a result of a chemical reaction between the reactants, resulting in products with less potential energy than the reactants. When a battery is connected to a circuit, its stored chemical energy is converted into electrical energy to "push" electrons through the circuit.

Light is unique it carries information it has no mass and it is insanely fast.

But what is light?

You can imagine it as a stream of photons (elementary particles) traveling from its source to surface of an object with a speed of light where they bounce of your eye. That very moment the information of a single photon in a form of energy is transmitted to your eyes and later on to your brain which processes the gathered information and constructs an image.

When you turn on the light you know that all the photons are coming from it the same thing is with nonanthropogenic light (natural light) we get about 99% from the sun and about 1% from the moon at night.

In the core of our sun elements are fused to make up heavier elements in this process energy is released (E=mc^2, where E is energy, m mass of a single atom fused inside star and c^2 the square of speed of light) in a form of photons and the type of photon (its frequency) determines if it will be visible to our eye and also determines the type of luminosity of stars.

Also if you were to track every single bit of information carried by any photon any time you would unravel the unfolding of the universe from the big bang to today.

A) Upward

In order to find the direction of the magnetic force on the wire, we can use the right-hand rule: the index finger, the middle finger and the thumb of the right hand must be placed all of them perpendicular to each other.

So we have:

- Index finger: direction of current in the wire (from west to east)

- Middle finger: direction of magnetic field (from south to north)

- Thumb: direction of the force --> so it will be upward

So, the force will point upward.

B) [tex]1.82\cdot 10^{-4}N[/tex]

The magnitude of the force exerted by the magnetic field on the wire is given by

[tex]F=ILB[/tex]

where

I = 1.50 A is the current in the wire

L = 2.20 m is the length of the wire

[tex]B=0.550 G = 0.55 \cdot 10^{-4}T[/tex]

Substituting into the equation, we find

[tex]F=(1.50 A)(2.20 m)(0.55 \cdot 10^{-4} T)=1.82\cdot 10^{-4}N[/tex]

Final answer:

The force exerted by the Earth's magnetic field on a wire carrying current from west to east is directed upwards. To determine the magnitude of the force, use the formula F = I × L × B × sin(θ) and calculate it to be approximately 0.1815 mN, where I represents current, L length, and B magnetic field.

Explanation:

The student's question involves finding the direction and magnitude of the force exerted by the Earth's magnetic field on a current-carrying wire oriented from west to east. To solve this, we use the right-hand rule for the direction and the formula F = I × L × B × sin(θ) for the magnitude.

Force Direction

Part A asks for the direction of the force. We apply the right-hand rule which indicates that if you point your thumb in the direction of current (from west to east, which is left to right) and your fingers in the direction of the magnetic field (from south to north, or bottom to top), your palm will face towards the direction of the force exerted on the wire. As the current flows from west to east and the Earth's magnetic field goes from south to north, the force on the wire will be directed upwards.

Force Magnitude

Part B asks for the magnitude of the force. The formula we use is F = I × L × B × sin(θ), where F is the force, I is the current (1.50 A), L is the length of the wire (2.20 m), B is the magnetic field, which should be converted from gauss to tesla (1 gauss = 1×10⁻⁴ tesla, so 0.550 gauss = 5.50×10⁻⁵ T), and θ is the angle between the wire and the magnetic field (90° here). With these values, we can calculate the force.

Let's calculate the force:
F = 1.50 A × 2.20 m × 5.50 × 10⁻⁵T × sin(90°)
F = 1.50 × 2.20 × 5.50 × 10⁻⁵ N
F = 0.1815 × 10⁻³ N
F ≈ 0.1815 mN

Answer:

The first flowering plants appeared in the Mesozoic era, not the Paleozoic era

Explanation:

The Mesozoic era is well known and most famous because of the rule of the dinosaurs which were the dominant animals for most of this are. Also, it is the era in which the mammals appeared, though they lived in the shadows of the dinosaurs and only became dominant after their extinction. Another important evolution that took place and is not mentioned very often is the appearance of the first flowering plants. This was a revolutionary trait for the plants, and it helped them to survive in the changing climate on Earth. Soon this trait enabled this type of plants to spread out significantly and to become one of the most dominant organisms on the planet in the following era.

a. 0.5 T

- The amplitude A of a simple harmonic motion is the maximum displacement of the system with respect to the equilibrium position

- The period T is the time the system takes to complete one oscillation

During a full time period T, the mass on the spring oscillates back and forth, returning to its original position. This means that the total distance covered by the mass during a period T is 4 times the amplitude (4A), because the amplitude is just half the distance between the maximum and the minimum position, and during a time period the mass goes from the maximum to the minimum, and then back to the maximum.

So, the time t that the mass takes to move through a distance of 2 A can be found by using the proportion

[tex]1 T : 4 A = t : 2 A[/tex]

and solving for t we find

[tex]t=\frac{(1T)(2 A)}{4A}=0.5 T[/tex]

b. 1.25T

Now we want to know the time t that the mass takes to move through a total distance of 5 A. SInce we know that

- the mass takes a time of 1 T to cover a distance of 4A

we can set the following proportion:

[tex]1 T : 4 A = t : 5 A[/tex]

And by solving for t, we find

[tex]t=\frac{(1T)(5 A)}{4A}=\frac{5}{4} T=1.25 T[/tex]

The time it takes for the mass to move through a distance of 2A is 2 times the period T, and the time it takes for the mass to move through a distance of 5A is 5 times the period T.

In terms of T, the time it takes for the mass to move through a total distance of 2A is:

t/T = 2

The time it takes for the mass to move through a total distance of 5A is:

t/T = 5

These equations show that the time it takes for the mass to move through a total distance is proportional to the number of times the amplitude is covered. Therefore, if the distance is 2A or 5A, it will take 2 or 5 times the period T, respectively.

Answer:

0.39

Explanation:

In order not to slide, you must have exactly the same acceleration of the train:

[tex]a=0.39 g[/tex]

where

g = 9.81 m/s^2

There is only one force acting on you: the static frictional force that "pulls" you forward, and it is given by

[tex]F_s = \mu_s mg[/tex]

According to Newton's second law, the net force acting on you (so, the frictional force) must be equal to your mass times the acceleration, so we have

[tex]F= ma = \mu_s mg[/tex]

from which we find

[tex]\mu_s = \frac{a}{g}=\frac{0.39 g}{g}=0.39[/tex]

so, the minimum coefficient of static friction must be 0.39.

The minimum coefficient of static friction required to prevent slipping on a train accelerating at 0.39g must be equal to or greater than 0.39.

To calculate the minimum coefficient of static friction required to prevent you from sliding on a train accelerating at 0.39g (where g is the acceleration due to gravity), you need to understand the relationship between static friction (Fs) and the normal force (N). Let's denote the coefficient of static friction as μs. The maximum force of static friction (μsN) should be equal to or greater than the force needed to overcome the train's acceleration to avoid slipping.

Since the acceleration of the train is 0.39g, and g is 9.81 m/s² (the acceleration due to gravity), the force due to the train's acceleration can be expressed as 0.39 × your mass × g. Considering that your mass × g gives us the normal force (N), the equation to avoid slipping becomes:

Fs ≥ 0.39 × N

Substituting the force of static friction equation (Fs = μs × N), we get:

μs × N ≥ 0.39 × N

Since N appears on both sides of the inequality, they cancel each other out, and you are left with:

μs ≥ 0.39

This means the minimum coefficient of static friction must be 0.39 or greater to prevent sliding.

Answer:

The maximum height of soccer ball  is 12.25 ft.

Explanation:

You know: H(t) = −16t² + vt + s

First you must know the value of the constant "s". For this you know that at the beginning, at time t = 0, the initial height H (0) is zero. Also, you know that the speed v is 28 feet per second. So:

H(0)=-16*0² + 28*0 + s

0=-16*0² + 28*0 + s

0=s

Then, the speed expression is determined as:

H(t) = −16t² + 28*t

The vertex is a point that is part of the parabola, which has the value as ordered  minimum or maximum function. At that point an imaginary axis can be drawn that makes  symmetric the graph of the function, which is called the axis of symmetry.

Being the parabola:  f(x)=a*x² + b*x + c

the vertex is calculated as: [tex](x,y)=(\frac{-b}{2*a} ,f(\frac{-b}{2*a}))[/tex]

In this case,  the point "x" of the vertex indicates the time at which the soccer ball reaches the maximum "y" height ( The vertex is at a maximum point of the function.) So, being a=-16 and b=28, the vertex is:

[tex]x=\frac{-b}{2*a} =\frac{-28}{2*(-16)}[/tex]

x=0.875

H(0.875)=-16*(0.875)²+28*(0.875)=12.25

The maximum height of soccer ball  is 12.25 ft.

Nuclear reaction

Hope this helps! =)

Explanation:

Explanation:

A chemical reaction is defined as the reaction that involves exchange of electrons between the reacting atoms.

For example, [tex]2Na(s) + Cl_{2}(g) \rightarrow 2NaCl[/tex]

Mass of Na = 23 g/mol

Mass of Cl = 35 g/mol

Mass of NaCl compound = (23 + 35) g/mol = 58 g/mol

So, in chemical reactions law of conservation of mass is obeyed because mass of reacting species is changing from one form to another.

Whereas in nuclear reactions there is splitting or combining of atomic nuclei of atom(s). Since, nuclei is involved in nuclear reaction so more energy is required.

Also, E = [tex]mc^{2}[/tex] so, in nuclear reactions mass of reacting atoms changes into energy. This results in formation of larger amount of energy.

Therefore, we can conclude that in situations involving equal masses, chemical reactions produce less energy than nuclear reactions.
