PLEASE HELP WILL GIVE BRAINLIEST!3. Given a bronze wire of length 2.5 m and cross sectional area 6.5 x 10-⁷ m². What is the elongation of the wire if it is stretched under a force of 10³ N? Given: Young modulus of bronze is 2.0 x 10-¹¹N/m².​

Answer:

1. directly

2. inversely

Explanation:

The relationship between the energy of a photon and its frequency is dictated by another simple equation:

E = hv = hc/λ

where E is the energy in kiloJoules per mole, h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle, λ is the wavelength of light λ in meters,  and c is the speed of light with a constant value of 300 million meters per second. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and vice versa.

Energy of a photon is directly proportional to frequency, and inversely proportional to wavelength.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form

The relationship between the energy of a photon and its frequency is

E = hv = hc/λ

where E is the energy in kiloJoules per mole,

h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle,

λ is the wavelength of light λ in meters,

The Jovian planets are formed from materials different from the terrestrial planets for the reason that gaseous Jovian planets, formed farther away from the heat of the Sun, are formed from light weight nebulae "dust."

A Jovian planet, also known as a gas giant, is a huge planet that has a primarily gaseous composition. The Jovian planets include Jupiter, Saturn, Uranus, and Neptune. They are primarily made up of hydrogen and helium, and they have enormous atmospheres.Jovian planets are formed farther away from the heat of the Sun, so they are formed from lighter-weight nebulae "dust." Terrestrial planets, on the other hand, are formed nearer to the Sun, so they are formed from heavier-weight nebulae "dust." The density of the materials that make up the Jovian planets is lower than that of the terrestrial planets due to this. This means that the Jovian planets have lower densities and a greater volume than the terrestrial planets.

Hence, the correct option is d. Gaseous Jovian planets, formed farther away from the heat of the Sun, are formed from light weight nebulae "dust."

When a person focuses on an object at a very far distance from the eye, the focal length of the eye at that time is approximately infinity.

The human eye is a complex optical system that can adjust its focus to objects at different distances. The lens of the eye changes its shape to allow for accommodation, enabling the eye to focus on objects at varying distances. However, when a person looks at an object located at an extremely far distance, such as a distant mountain or star, the light rays entering the eye can be considered nearly parallel.

In this scenario, the lens of the eye becomes relatively flat and reaches its least curved state. As a result, the focal length of the eye approximates infinity. Essentially, the eye's focusing mechanism is optimized for parallel light rays, allowing the incoming light to converge at a point that is virtually at an infinite distance from the eye. This enables clear vision and sharp focus on objects situated at extremely far distances.

Explanation:

The answer is that the charge density in an electric point-electron is (1/2)e2/r. So, in this example we have σE = (1/2)e^2/(4.40 × 10^6 cm).

A charge of -323e is uniformly distributed over the volume of a 5.00 cm sphere. The charge density = 1.9 ×10 -19 C/m3.

The volume charge density of this sphere is 4.40C/m^3 with C being the charge of 1 coulomb and m_s being the sphere radius.

The volume charge density in this case is equal to the charge density of a sphere that occupies the same volume and has the same radius.

We can substitute the given values into the equation to find the speed of sound in the metal bar. Just plug in L = 5.0 m, Δt = 8.20 × \(10^{-3\) s, and the speed of sound in air (v_air).

To solve this problem, we can use the fact that the speed of sound in air and in the metal bar are different.

Let's denote the speed of sound in air as v_air and the speed of sound in the metal bar as v_metal.

- Length of the metal bar (L) = 5.0 m

- Time difference between the two pulses (Δt) = 8.20 ms = 8.20 × \(10^{-3\) s

We know that the time it takes for the sound to travel through the air can be calculated using the formula: Δt_air = L/v_air. Similarly, the time it takes for the sound to travel through the metal bar can be calculated using: Δt_metal = L/v_metal.

We are given the time difference between the two pulses, Δt = Δt_metal - Δt_air. Substituting the values, we get: Δt = L/v_metal - L/v_air.

We can solve this equation for v_metal by rearranging the terms: v_metal = L / (Δt + L/v_air).

Answer:

Inner planets are small because the heat of the Sun baked off the hydrogen. The outer planets are large because they were colder and did not get the hydrogen baked off. Among the outer planets, they get smaller as you get further out because they formed nearer the edge of the cloud that supplied the material. There was just less to build from.

The  wavelength of the waves is much smaller than 10 centimeters. The exact value of the wavelength cannot be determined from this observation alone.

According to the principle of diffraction, when waves pass through an opening or aperture, they tend to diffract or bend around the edges of the opening. The amount of diffraction depends on the size of the opening and the wavelength of the waves.

If waves pass through a 10-centimeter opening in a barrier without being diffracted, it means that the opening is much larger than the wavelength of the waves. In other words, the size of the opening is not significant enough to cause diffraction of the waves.

Therefore, we can conclude that the wavelength of the waves is much smaller than 10 centimeters. The exact value of the wavelength cannot be determined from this observation alone.

The average acceleration of the hockey puck is 1.5172m/s² and the hockey puck travels 110.65 meters in the interval of 5.8 seconds.

The initial velocity of the player is 14.7m/s. The final velocity of the player is 5.90 m/s.

The time taken during the change of velocity is 5.8 seconds.

a) Average acceleration A of tha player,

A = ∆V/∆t

∆V total change in velocity,

∆t total change in time,

So, we can write,

A = 5.90-14.7/5.8

A = 1.5172m/s².

So, average acceleration is 1.5172m/s².

b) To find the distances travelled in the 5.8 second,

We can use the equation of motion,

S = Ut+1/2At²

U is initial velocity,

A is average acceleration,

t is the time,

S is the distance travelled,

Putting all the values,

S = 14.7(5.8)+1/2(1.51)(5.8)²

S = 110.65 meters.

Answer:Yes, water indeed expands when it changes form from liquid to solid. And this is because water has a property called “hydrogen bonds”, and these bonds occur between each water molecule. But when water is in a liquid form these hydrogen bonds break more easily and occur less frequently. When the temperature drops the kinetic energy also drops, which in turn makes hydrogen bonds form more frequently. So the water molecules form a lattice, which is less dense than regular liquid water.

Let's start with the concept of momentum. What is it? Linear momentum in physics is mathematically written as a product of mass and velocity of an object. Now let us suppose a body of mass m is moving in an inertial frame of reference with velocity v. Consider the fact that no external force is acting on the system. The momentum of this body is given by mv, where m is the mass and v is its velocity. In case of simple real world problems not delving into the realms of relativity, mass is a conserved quantity and it cannot be zero. Hence the velocity of the body must be zero and hence the momentum.

However, photons are considered to have a rest mass zero.

However note the point carefully "rest mass". A body in motion cannot have mass to be zero.

The dark-adapted eye can detect 120 photons of light with a wavelength of 500 nm per second.

If the dark-adapted eye can supposedly detect one photon of light of wavelength 500 nm, and 120 such photons enter the eye each second, we can make a few calculations based on this information.

First, let's determine the energy of a single photon using the formula:

\(E = hc/λ\)

Where:

E is the energy of a photon,

h is Planck's constant (approximately \(6.626 x 10^-34\) J·s),

c is the speed of light (approximately\(3.0 x 10^8 m/s\)), and

λ is the wavelength of light.

Substituting the given values:

E = (\(6.626 x 10^-34\) J·s)(\(3.0 x 10^8 m/s\))/(\(500 x 10^-9 m)\)

\(E ≈ 3.9768 x 10^-19 J\)

Now, let's calculate the total energy entering the eye per second:

Total energy = Energy per photon × Number of photons per second

Total energy = (\(3.9768 x 10^-19\) J/photon) × 120 photons/s

Total energy ≈ \(4.7722 x 10^-17 J/s\)

Therefore, approximately \(4.7722 x 10^-17\) Joules of energy enter the eye each second when 120 photons of wavelength 500 nm enter the dark-adapted eye.

Answer:

wood ,clay brick ,aluminum, and copper.

Explanation:

Three examples of types of material that would be used when building houses where their thermal conductivity are copper, aluminum, fire brick, and carbon steel.

Thermal conductivity is the rate at which heat is transferred from one object to another by conduction over a material's unit cross-section area.

Therefore, a substance's thermal conductivity will decrease as the distance between its atoms increases.

This is because a substance's molecules will move more randomly with the greater distance between them, which will lead to less efficient energy transfer. Metals have a much higher heat conductivity than liquids.

Therefore, copper, aluminum, fire brick, and carbon steel are three examples of materials whose heat conductivity would be employed for constructing homes.

The inductance in the Buck circuit is discharged when (C) the diode is off. In the Buck circuit, the inductor is charged when the switch is closed, allowing current to flow through it.

When the switch is opened, the current in the inductor wants to continue flowing, but the diode blocks this flow. As a result, the inductor discharges its energy through the diode, and the inductance is effectively discharged.

Under steady-state conditions, the inductor current (C) remains unchanged when the switch is turned off in the Boost circuit. In the Boost circuit, the inductor is charged when the switch is closed, and the current through the inductor increases.

When the switch is turned off, the inductor tries to maintain the current flowing through it, but the energy is transferred to the output load. The inductor current may experience a slight decrease due to the load, but it remains relatively constant or unchanged in steady-state conditions.

In summary, in the Buck circuit, the inductance is discharged when the diode is off, while in the Boost circuit, the inductor current remains unchanged when the switch is turned off.

The deceleration of a snowboarder going up is 1.8 m / s²

We know that,

F = m * a

\(f_{k}\) = μ\(_{k}\) * \(F_{N}\)

F = Force

m = Mass

a = Acceleration

\(f_{k}\) = Kinetic frictional force

μ\(_{k}\) = Co-efficient of kinetic friction

\(F_{N}\) = Normal force

θ = 5°

μ\(_{k}\) = 0.1

Since the snowboarder is going up the hill at an angle of 5°, the weight of the snowboarder does not align with the traditional y-axis direction. So resolving the weight into horizontal and vertical components.

sin 5° = - \(W_{x}\) / W

\(W_{x}\) = - W sin 5°

cos 5° = - \(W_{y}\) / W

\(W_{y}\) = - W cos 5°

\(f_{k}\) = 0.1 ( \(W_{y}\) )

\(f_{k}\) = - 0.1 ( W cos 5° )

Σ \(F_{x}\) = m \(a_{x}\)

\(W_{x}\) + \(f_{k}\) = m \(a_{x}\)

- W sin 5° - 0.1 ( W cos 5° ) = m \(a_{x}\)

- W ( sin 5° + 0.1 cos 5° ) = m \(a_{x}\)

- m g ( sin 5° + 0.1 cos 5° ) = m \(a_{x}\)

- 9.8 ( sin 5° + 0.1 cos 5° ) = \(a_{x}\)

\(a_{x}\) = - 1.8 m / s²

Deceleration is the negative acceleration. When an object slows down it has deceleration. Kinetic friction is the frictional force created due to an object's motion.

Explanation:

According to newton's 3rd law of motion, the action and reaction force act in two different objects. For every action, there is an equal and opposite reaction.

Let F₁₂ is the force that object 1 experienced on object 2 and F₂₁ is the force that object 2 will experience on object 2. So,

F₁₂ = -F₂₁

So, an action-reaction pair of forces have equal magnitudes in the opposite direction.

The percent uncertainty in the measurement of an infant's pulse rate, which is recorded as 135 +/- 6 beats/min, is 4.4%.

The percent uncertainty is calculated by dividing the range of the measurement (in this case, 6 beats/min) by the average value of the measurement (in this case, 135 beats/min), and then multiplying by 100 to express it as a percentage. In this case, the range is 6 beats/min and the average value is 135 beats/min. Dividing 6 by 135 gives 0.0444, and multiplying by 100 gives 4.44%. Therefore, the percent uncertainty in this measurement is 4.4%.

This measurement indicates that the pulse rate of the infant can vary within a range of +/- 6 beats/min from the average value of 135 beats/min. The percent uncertainty provides a measure of the relative variability or precision of the measurement. A lower percent uncertainty would indicate a more precise measurement with less variability, while a higher percent uncertainty would indicate a less precise measurement with greater variability. In this case, a percent uncertainty of 4.4% suggests a reasonably precise measurement of the infant's pulse rate.

Answer:

There are three types of friction.

1. Slanting friction

2. Sliding friction

3. Rolling friction

In the first two types of friction, the body of the object will come in contact with the irregularities on the surface more than in the case of rolling friction, thus a heavy box in square shape will have more friction than a heavy-duty vehicle.

This is also the reason why all vehicles are having wheels as they reduce friction and makes transportation easier and many people suggest to use a small log of wood to be placed on the bottom of a heavy box with flat bottom so it can moved easily due to reduction of friction
