The threshold wavelength for emission from a metallic surface is 500 nm and the work function for that particular metal is \(3.98 \times 10^{-19} J\).  The maximum speed of a photoelectron produced by each of the following wavelengths of light i) 400 nm is 8.2x10⁵ m/s ii) 500 nm is 5.16 x 10⁵ m/s and iii) 600 nm is 3.41 x 10⁵ m/s.

The work function of the metal can be given by the formula; hf = Φ + KE. Here, Φ is the work function of the metal and KE is the maximum kinetic energy of the photoelectron. The threshold frequency for the metal can be given as; f = c / λ. 500 nm is the threshold wavelength for the emission of electrons from the metallic surface. So, the corresponding frequency can be calculated as;

\(f = (3 \times 10^8) / (500 \times 10^{-9}) = 6 \times 10^{14} Hz\). The value of the plank constant can be taken as; h = \(6.63 \times 10^{-34} Js\). Now, the work function of the metal can be calculated as;
hf = Φ + KEΦ = hf - KE =\((6.63 \times 10^{-34}) \times (6 \times 10^{14}) - 0 = 3.98 \times 10^{-19} J\)

(b) Calculate the maximum speed of a photoelectron produced by each of the following wavelengths of light:
i) 400 nm) The frequency of the light is given by; f = c / λf \(= (3 \times 10^8) / (400 \times 10^{-9}) = 7.5 \times 10^{14} Hz.\).
The maximum kinetic energy of the photoelectron is given by;

KE = hf - ΦKE =\((6.63 \times 10^{-34}) \times (7.5 \times 10^{14}) - 3.98\times 10^{-19} = 3.61 \times 10^{-19} J.\)
The maximum speed of the photoelectron can be given by;
KE = 1 / 2 mv². So. v = √(2KE / m).
So, \(v = \sqrt {(2 \times 3.61  \times 10^{-19} / 9.1  \times 10^{-31})} = 8.2 \times 10^5 m/s.\)
ii) The frequency of the light is given by; f = c / λf \(= (3 \times 10^8) / (500 \times 10^{-9})= 6 \times 10^{14} Hz\).
The maximum kinetic energy of the photoelectron is given by;
KE = hf - ΦKE =\((6.63 \times 10^{-34}) \times (6 \times 10^{14}) - 3.98 \times 10^{-19} = 1.65 \times 10^{-19} J.\).
The maximum speed of the photoelectron can be given by; v = \(\sqrt {(2 \times 1.65 \times 10^{-19} / 9.1 \times 10^{-31})} = 5.16 \times 10^5 m/s\)
iii) The frequency of the light is given by; f = c / λf = \(= (3 \times 10^8) / (600 \times 10^{-9})= 5 \times 10^{14} Hz\),
The maximum kinetic energy of the photoelectron is given by;
KE = hf - ΦKE = \((6.63 \times 10^{-34}) \times (5 \times 10^{14}) - 3.98 \times 10^{-19} = 9.62 \times 10^{-20} J.\).
The maximum speed of the photoelectron can be given by; v = \(\sqrt {(2 \times 9.62 \times 10^{-20} / 9.1 \times 10^{-31})} = 3.41 \times 10^5 m/s\).

Electron must pass the potential difference of ΔV ≈ -798.1 V to accomplish this.

The negative sign indicates that the electron needs to pass through a potential difference of 798.1 V (volts) in the opposite direction of the electric field to achieve the desired acceleration.

To calculate the potential difference through which an electron must pass to accelerate from a velocity of 5.00×10^6 m/s to 7.00×10^6 m/s, we can use the kinetic energy equation for a moving charged particle:

ΔK = qΔV

where ΔK is the change in kinetic energy, q is the charge of the electron, and ΔV is the potential difference.

The change in kinetic energy can be calculated using the formula:

ΔK = (1/2)mv^2_final - (1/2)mv^2_initial

where m is the mass of the electron, v_final is the final velocity, and v_initial is the initial velocity.

Substituting the given values:

ΔK = (1/2)(9.11×10^-31 kg)(7.00×10^6 m/s)^2 - (1/2)(9.11×10^-31 kg)(5.00×10^6 m/s)^2

ΔK ≈ 1.277 × 10^-16 J

Since the charge of the electron is -1.6 × 10^-19 C, we can rearrange the equation to solve for the potential difference:

ΔV = ΔK / q

ΔV = (1.277 × 10^-16 J) / (-1.6 × 10^-19 C)

ΔV ≈ -798.1 V

The negative sign indicates that the electron needs to pass through a potential difference of 798.1 V (volts) in the opposite direction of the electric field to achieve the desired acceleration.

The correct answer is B. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

In simpler terms, as objects get closer together, the gravitational force between them increases.

When the distance between two objects decreases, the denominator of the equation (distance squared) becomes smaller, resulting in a larger force. Conversely, when the distance increases, the denominator becomes larger, resulting in a smaller force.

It is important to note that the mass of an object does not directly affect the strength of the gravitational force between two objects. However, a higher mass will lead to a greater gravitational force when compared to a lower mass, but only because the force is being exerted on a more massive object. The mass of an individual object doesn't directly affect the gravitational force it experiences from another object. option B

According to the law of reflection, the angle of reflection must be equal to the angle of incidence of a ray of light:

Therefore, the angle of reflection of the ray of light is:

That is the answer.

The value of a in units of nm^-1 is 343, we have a one-dimensional potential with a wavefunction given by ψ(x) = Be^(-ax).

We are given the value of k = 60 nm^-1 and b = 0.0016666666666667 nm.

To find the value of a, we can use the relation k = √(2M(U-E))/ℏ, where M is the mass of the particle, U is the potential energy, E is the energy of the particle, and ℏ is the reduced Planck's constant.

Since the particle is in a bound state, its energy E is negative. In this case, E = -U, so we can substitute E = -U in the above equation.

Now, rearranging the equation and solving for a, we get a = \(√((2M(U-E))/ℏ) = √((2M(U+U))/ℏ) = √((4MU)/ℏ) = √((4M(-U))/ℏ).\)

Plugging in the values, a = \(√((4M(-U))/ℏ) = √((4(17me)(-U))/ℏ) = √((4(17me)(-(-U)))/ℏ) = √((4(17me)(U))/ℏ) = √((4(17me)(U))/(h/(2π))).\\\)

Now, substituting U = k^2ℏ^2/(2M), we get a =\(√((4(17me)(k^2ℏ^2/(2M)))/(h/(2π))) =\) \(√((4(17me)(k^2ℏ^2)/(2M))/(h/(2π))) = √((2(17me)(k^2ℏ^2))/(M)).\)

Plugging in the given values, a =

\(√((2(17me)(k^2ℏ^2))/(M)) = √((2(17me)(60^2(6.62607015x10^(-34))^2))/((17me))) = √((2(60^2(6.62607015x10^(-34))^2))).\)

Answer:

5.59 m/s

Explanation:

We are given;

Mass = 110 kg

Initial velocity: u = 13.41 m/s

Force = 615 N

Time(t) = 1 s

Now, formula for force is;

Force = mass x acceleration

Thus;

615 = 110 × acceleration

Acceleration(a) = 615/110 = 5.591 m/s²

Now, using Newton's first law of motion, we can find acceleration (a). Thus;

v = u + at

v = 13.41 + (5.591 × 1)

v ≈ 19 m/s

So, change in velocity is;

Final velocity(v) - Initial velocity(u) = 19 - 13.41 = 5.59 m/s

Employing a single cost comparison model provides a practical approach to evaluating the cost effectiveness of local sourcing in the context of distance and vulnerability in supply chains and procurement systems.

A practical step to determine the cost effectiveness of local sourcing in the given scenario would be to utilize a single cost comparison model.

This model would involve comparing the costs associated with local sourcing against those of distant sourcing, taking into account factors such as transportation costs, lead times, inventory holding costs, quality control measures, and any other relevant expenses.

The cost comparison model would involve gathering data on the various cost components associated with both local and distant sourcing options.

This would include collecting information on the prices of raw materials, transportation costs, import/export duties, storage costs, and any other relevant expenses.

The model would then calculate the total cost for each sourcing option and compare them to determine which one is more cost-effective.

By utilizing a single cost comparison model, organizations can systematically assess the financial implications of local sourcing.

This step allows for an objective evaluation of the costs involved and enables decision-makers to make informed choices based on a comprehensive understanding of the economic factors at play.

The best description of the origin of the energy held within fossil fuels is (b) The energy within fossil fuels comes from ancient autotrophs that decomposed long ago and went through geologic processes over millions of years.

Fossil fuels such as coal, oil, and natural gas are formed from the remains of ancient organisms. These organisms, known as autotrophs, were primarily plants and microscopic algae that lived millions of years ago. Through the process of photosynthesis, these autotrophs converted sunlight, carbon dioxide, and water into organic matter, storing energy from the sun in their tissues.

Over time, as these ancient autotrophs died and were buried under layers of sediment, they underwent decomposition and were subjected to intense heat and pressure. These geologic processes, occurring over millions of years, transformed the organic matter into fossil fuels.

Dinosaurs, on the other hand, were reptiles that lived during the Mesozoic Era, which was much more recent compared to the formation of fossil fuels. The misconception that fossil fuels come from dinosaurs is incorrect.

Answer:We can use the equation for linear velocity to angular velocity conversion to find the angular velocity of the forearm:

v = r x w

where v is the linear velocity, r is the distance from the axis of rotation, and w is the angular velocity.

In this case, the linear velocity is the velocity of the ball in the pitcher's hand, which is 35.0 m/s. The distance from the elbow joint to the ball is 0.300 m. Therefore, we have:

35.0 m/s = 0.300 m x w

Solving for w, we get:

w = 35.0 m/s / 0.300 m

w = 116.7 rad/s

Therefore, the angular velocity of the forearm is 116.7 rad/s.

Explanation:

If the velocity of the ball in the pitcher’s hand is 35.0 m/s and the ball is 0.300 m from the elbow joint, therefore, the angular velocity of the forearm during the pitch is 116.67 rad/s.

Velocity is a measure of the rate of motion of an object in a particular direction, usually expressed as distance traveled per unit of time. It is a vector quantity that includes both speed and direction.

Angular velocity is the rate at which an object rotates around a fixed axis or point, usually expressed in radians per unit of time. It is a vector quantity that includes both magnitude and direction.

If the velocity of the ball in the pitcher’s hand is 35.0 m/s and the ball is 0.300 m from the elbow joint then to  find the angular velocity of the forearm, we need to use the formula:
angular velocity = velocity / radius
where velocity is the velocity of the ball in the pitcher’s hand and radius is the distance from the elbow joint to the ball.
Given that the velocity of the ball in the pitcher’s hand is 35.0 m/s and the ball is 0.300 m from the elbow joint, we can plug these values into the formula:
angular velocity = 35.0 m/s / 0.300 m
angular velocity = 116.67 rad/s
