A current of 2.0 A flows through a circuit containing a motor with a resistance of 12 ohm how much energy is converted if the motor runs for a minute

At 0.474 degrees angle the first-order maximum for 455-nm wavelength blue light falling on double slits separated by 0.0550 mm.

Using the formula for the first-order maximum in a double-slit experiment, we have:

sin(θ) = (mλ) / d

where θ is the angle of the first-order maximum, m is the order number (1 for first-order maximum), λ is the wavelength of the light (455 nm), and d is the separation between the slits (0.0550 mm).

First, let's convert the units: λ = 455 nm = 455 x 10^(-9) m, and d = 0.0550 mm = 0.0550 x 10^(-3) m.

Now, we can calculate sin(θ):

sin(θ) = (1)(455 x 10^(-9) m) / (0.0550 x 10^(-3) m)

sin(θ) ≈ 0.00827273

To find the angle θ in degrees, we take the inverse sine (arcsin) of the calculated value:

θ ≈ arcsin(0.00827273) ≈ 0.474 degrees

The resistance of a wire depends on its length, cross-sectional area, and the resistivity of the material it is made of. The resistivity is a material property that determines how strongly a material opposes the flow of electric current.

In this case, we have two wires made of the same material, so they have the same resistivity. Let's calculate the resistance of the second wire.

The resistance of a wire can be calculated using the formula: R = (ρ * L) / A

Where:

R is the resistance,

ρ (rho) is the resistivity,

L is the length of the wire, and

A is the cross-sectional area of the wire.

For the first wire:

Length (L1) = 10 m

Diameter (d1) = 1.0 mm

Radius (r1) = d1 / 2 = 0.5 mm = 0.5 * 10^(-3) m

Cross-sectional area (A1) = π * (r1)^2 = π * (0.5 * 10^(-3))^2

Resistance (R1) = 5.0 Ω

Using the formula, we can rearrange it to solve for resistivity (ρ):

ρ = (R * A) / L

Substituting the values for the first wire:

ρ = (5.0 * π * (0.5 * 10^(-3))^2) / 10

Now, let's calculate the resistance of the second wire:

Length (L2) = 3.0 m

Diameter (d2) = 4.0 mm

Radius (r2) = d2 / 2 = 2.0 mm = 2.0 * 10^(-3) m

Cross-sectional area (A2) = π * (r2)^2 = π * (2.0 * 10^(-3))^2

Resistance (R2) = ?

Using the formula:

R2 = ρ * (L2 / A2)

Substituting the values:

R2 = ρ * (3.0 / (π * (2.0 * 10^(-3))^2))

Now, substitute the value of ρ we obtained earlier:

R2 = (5.0 * π * (0.5 * 10^(-3))^2) / 10 * (3.0 / (π * (2.0 * 10^(-3))^2))

Simplifying the expression:

R2 = (5.0 * (0.5 * 10^(-3))^2) / 10 * (3.0 / (2.0 * 10^(-3))^2)

R2 ≈ 1.875 Ω

Therefore, the resistance of the second wire is approximately 1.875 ohms.

Explanation:

F= M*A equation

A projectile is launched at an angle of 33⁰ above the horizontal, then the projectile launched at an angle of 90 - 33 = 57⁰ will have the same range as the projectile launched at 33⁰. The correct option is (B) 57⁰.

In the absence of air resistance, a projectile launched at an angle of 33 above the horizontal will have the same range as a projectile launched at an angle of 57⁰.

The range of a projectile can be determined by using the range formula.

R = ((v^2 * sin(2θ))/g) Where

R is the range of the projectile,

v is the velocity of the projectile,

θ is the angle at which the projectile is launched, and

g is the acceleration due to gravity.

In the absence of air resistance,

the horizontal component of velocity of a projectile remains constant throughout the flight.

So, the range of a projectile depends only on its initial velocity and the angle at which it is launched.

If a projectile is launched at an angle θ,

the time of flight of the projectile can be calculated by using the following formula:

T = (2v * sin(θ))/g

The maximum height reached by the projectile is given by the formula:

H = (v^2 * sin^2(θ))/2gIf a projectile is launched at an angle θ, then the range of the projectile will be the same as the range of the projectile launched at an angle of (90 - θ).

So, if a projectile is launched at an angle of 33⁰ above the horizontal, then the projectile launched at an angle of 90 - 33 = 57⁰ will have the same range as the projectile launched at 33⁰.

Therefore, the correct option is (B) 57⁰.

When four or more current-carrying conductors are bundled together for more than 24 inches, the conductor's allowable ampacity must be reduced according to the factors listed in Table 310-15(b)(3a) of the National Electrical Code (NEC).

This is known as ampacity derating, and it is necessary because when conductors are bundled together, they can generate more heat than when they are spaced apart.

This additional heat can cause the conductors to exceed their temperature rating and potentially create a safety hazard. By reducing the allowable ampacity, the risk of overheating and fire can be minimized, ensuring the safety and reliability of the electrical system.

to find the modulus of elasticity MoE at 23% of moisture content based on the already given modulus of elasticity of 12% moisture content we need to consider a shrinkage behavior of material. the expected MoE comes out to be approximately \(6,836 N/mm².\)

given information:

Modulus of elasticity at 12% moisture content =7,920 N/mm²

resultant shrinkage or final shrinkage percentage FSP = 30%

To calculate the expected MoE at 23% moisture content we have the following equation:

MoE-23% =   \(MoE-12%\) \((1 - FSP (23 - 12) / (100 - 12))\)

MoE-23% = \(7,920 N/mm² × (1 - 0.30 × (23 - 12) / (100 - 12))\)

MoE-23% =\(7,920 N/mm² × (1 - 0.30 × 11 / 88)\)

MoE-23% = \(7,920 N/mm² × (1 - 0.1364)\)

MoE-23% = \(7,920 N/mm² × 0.8636\)

MoE-23% =  \(6,836 N/mm²\)

therefore the expected modulus of elasticity at 23% moisture content comes out to be approx \(6,836 N/mm²\).

The light from the green glow stick held by the Olympic sprinter will appear redshifted.

The phenomenon of redshift occurs when the source of light is moving away from the observer. In this case, as the sprinter is running towards you, the distance between you and the glow stick is decreasing over time. This decrease in distance causes a Doppler shift in the frequency of the light emitted by the glow stick.

Since the light is redshifted, its wavelength increases and the frequency decreases compared to its original emitted frequency. As a result, the light that reaches your eyes appears more towards the red end of the visible spectrum.

It is important to note that the color of the glow stick itself remains the same, but due to the relative motion between the source (the sprinter) and the observer (you), the light undergoes a change in frequency and appears redshifted.

This phenomenon is similar to the redshift observed in cosmology, where the light from distant galaxies appears to be redshifted due to the expansion of the universe.

The factor by which the displacement will change is 3.0, and the answer is option b.

The displacement of a spring's lower end is directly proportional to the weight suspended from it. This relationship is expressed by Hooke's law, which states that the displacement (x) of a spring is equal to the force (F) applied to it divided by its spring constant (k), or x = F/k.
In this scenario, we are tripling the weight suspended vertically from a coil spring. According to Hooke's law, if the weight is tripled, the force applied to the spring will also triple. Since the displacement is directly proportional to the force, we can say that the displacement will also triple.
Therefore, the factor by which the displacement will change is 3.0, and the answer is option b.

For a normalized wave function, Ψ = cΨₙ + c’Ψₙ', Where Ψₙ and Ψₙ' represent any two normalized stationary states of the particle with n ≠ n'.The complex constants c and c’ must satisfy the following condition for Ψ to be a normalized wave function:|c|² + |c’|² = 1.

Given Ψ = cΨₙ + c’Ψₙ', the probability density |Ψ|² for finding the particle in the box is given by:|Ψ|² = |cΨₙ + c’Ψₙ'|²=|c|²|Ψₙ|² + |c’|²|Ψₙ'|² + 2Re(c*c'*(Ψₙ*Ψₙ')), where Re( ) represents the real part of the quantity in the bracket.

Given that a particle is in its first excited state and is confined to the interval [-a/2, a/2], the probability of finding the particle in the subinterval (a/8, a/4) is given by:P = ∫ (a/4, a/2) |Ψ|²dx.

For a particle in its first excited state, n = 2 and the wave function is given by:Ψ2(x) = √(2/a)sin(2πx/a)Therefore,Ψₙ = Ψ2 = √(2/a)sin(2πx/a)andΨₙ' = Ψ1 = √(2/a)sin(πx/a).

Substituting these values in the given wave function, Ψ = cΨ2 + c’Ψ1. We know that the wave function Ψ is normalized. Therefore,|c|² + |c’|² = 1.

Consider the subinterval (a/8, a/4).

The probability of finding the particle in this subinterval is given by:P = ∫(a/8, a/4) |Ψ|²dxP = |c|² ∫(a/8, a/4) |Ψ2|²dx + |c’|² ∫(a/8, a/4) |Ψ1|²dx + 2Re(c*c' ∫(a/8, a/4) Ψ2*Ψ1 dx).

Substituting the given wave functions,Ψ2 = √(2/a)sin(2πx/a)andΨ1 = √(2/a)sin(πx/a) in the above equation,P = |c|² ∫(a/8, a/4) [(2/a)sin(2πx/a)]²dx + |c’|² ∫(a/8, a/4) [(2/a)sin(πx/a)]²dx + 2Re(c*c' ∫(a/8, a/4) [(2/a)sin(2πx/a)][(2/a)sin(πx/a)]dx).

Solving the integral,∫sin²(ax)dx = x/2 - (1/4a)sin(2ax).

Therefore, the probability of finding the particle in the subinterval (a/8, a/4) is:P = |c|² [(a/2π) cos(π/4)] + |c’|² [(a/4)] + (ac*c')/4π (where Re(c*c') = 1/2 (|c|² + |c’|² + c*c')).

The fastest stars are the ones with c) the dots farthest apart.

In the diagram, each dot represents the position of a star at one-year intervals. The greater the distance between the dots, the more the star has moved within that one-year time frame.

Stars with dots close together indicate that the star is moving relatively slowly in its orbit because it has not traveled as far in the same one-year interval. On the other hand, stars with dots farther apart are moving faster because they have covered a larger distance in the same amount of time. This faster movement can be attributed to various factors, such as the mass and proximity of the objects they are orbiting, as well as the overall characteristics of their orbits.

In summary, by examining the distances between the dots representing the stars' positions at one-year intervals, we can determine their relative speeds. Stars with dots farther apart are moving the fastest in their orbits during the time period indicated by the dots. Therefore, option C is correct.
