Which observation supports a model of the nature of light in which light acts as a wave

The kinetic energy of the ball is 450 J.

We have to note that the kinetic energy that the body has is the energy that the body has due to the fact that the body is in motion. This is why the object that undergoing kinetic energy must have a velocity of the object.

We have to note that the kinetic energy can be given using the formula;

KE = 0.5mv^2

KE = kinetic energy

m = mass of the object

v = velocity of the object'

Then we have;

KE = 0.5 * 4 * 15^2

Inelastic collision and a host of other factors causes the loss of energy.

Kinetic energy of an object is the energy that it possesses due to motion.

It can be defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. When it has gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

In an inelastic collision which is the case of ball X and Y, the kinetic energy of the system is not conserved. The energy that you find lost has been dissipated as other forms of energy. This can be heat, friction, vibrational energy transferred to atoms of the colliding particles, energy lost to deform the atomic structure etc.

In conclusion, the inelastic collision nature of the two balls results in the loss of energy through different forms.

Answer:

Explanation:

Let's look at a mathematical representation of this. The equation for tis is just a souped up version of Newton's 2nd Law:

F - f = ma. It an object is moving at a constant speed, the acceleration of that object is 0. That changes this equation to

F = f which states that the applied Force equals the frictional force, choice a.

If l be the length of the field and w be the width of the field then, the dimensions of the field are l=150 yards and w=150 yards.

Let the width of the rectangular field be w yards. Since the length of the rectangular field is twice the width, then the length of the rectangular field is 2w yards.

The perimeter of a rectangle is given by the equation

\(P = 2(l + w)\) where P is the perimeter, l is the length, and w is the width.

So for the rectangular field, we have:

\(P = 2(2w + w)\)  (since the length is 2w)

\(P = 2(3w)P = 6w\) yards

Since the perimeter of the rectangular field is 450 yards, then we have:\(6w = 450\)

Divide both sides of the equation by 6 to isolate w:\(6w/6 = 450/6w = 75\) yards

Therefore, the width of the rectangular field is 75 yards. The length of the rectangular field is twice the width. Thus the length of the rectangular field is: \(2w = 2(75) = 150\) yards.

Therefore, the dimensions of the rectangular field are 75 yards by 150 yards.

The frequency of an x-ray having a wavelength of 2.5×10⁻⁷ cm is 1.2×10¹⁷ Hz

We'll begin by converting the value of the wavelength from cm to m. Details below:

100 cm = 1 m

Therefore

2.5×10⁻⁷ cm = (2.5×10⁻⁷ cm × 1 m) / 100

2.5×10⁻⁷ cm = 2.5×10⁻⁹ m

Finally, we shall determine the frequency of the x-ray. This is shown below:

Velocity (v) = wavelength (λ) × frequency (f)

3×10⁸ = 2.5×10⁻⁹ × frequency

Divide both sides by 2.5×10⁻⁹

Frequency = 3×10⁸ / 2.5×10⁻⁹ m

Frequency = 1.2×10¹⁷ Hz

Red light, greenish-blue light, and violet light will not be seen in the reflected light from the soap bubble.

When white light is incident on a soap bubble, interference effects occur due to the difference in the optical path length traveled by the light waves reflected from the two surfaces of the soap film.

This interference causes certain colors to be enhanced or suppressed in the reflected light.

To determine which colors are not seen in the reflected light, we need to consider the conditions for constructive and destructive interference. Constructive interference occurs when the path length difference between the two reflected waves is an integer multiple of the wavelength, leading to reinforcement and a bright color.

Destructive interference occurs when the path length difference is a half-integer multiple of the wavelength, resulting in cancellation and the absence of that color.

The path length difference in the soap film can be calculated using the equation:

Path Length Difference = 2 * thickness * index of refraction

Given that the soap bubble has a thickness of 250 nm (or 250 x 10^-9 m) and an index of refraction of 1.36, we can calculate the path length difference:

Path Length Difference = 2 * (250 x 10^-9 m) * 1.36 = 680 x 10^-9 m

Now, let's consider the colors and their corresponding wavelengths in the visible spectrum:

Red light has a wavelength of approximately 700 nm.

Violet light has a wavelength of approximately 400 nm.

Colors that are not seen in the reflected light correspond to wavelengths for which the path length difference leads to destructive interference. In other words, colors that have a path length difference close to a half-integer multiple of their wavelengths will be suppressed.

To find which colors are not seen, we can look for the range of wavelengths for which the path length difference is close to an odd half-integer multiple.

In this case, the path length difference of 680 x 10^-9 m is approximately equal to the odd half-integer multiples of the wavelength:

(2n - 1) * (λ/2)

where n is an integer.

Solving for λ (wavelength), we can find the corresponding colors that are not seen:

(2n - 1) * (λ/2) = 680 x 10^-9 m

Simplifying the equation, we have:

λ = (680 x 10^-9 m) / (2n - 1)

Plugging in values for n, we can calculate the corresponding wavelengths. The colors that correspond to these wavelengths will not be seen in the reflected light.

For n = 1: λ = (680 x 10^-9 m) / (2(1) - 1) = 680 x 10^-9 m (Red)

For n = 2: λ = (680 x 10^-9 m) / (2(2) - 1) = 340 x 10^-9 m (Greenish-Blue)

For n = 3: λ = (680 x 10^-9 m) / (2(3) - 1) = 227 x 10^-9 m (Violet)

Based on these calculations, red light, greenish-blue light, and violet light will not be seen in the reflected light from the soap bubble.

On the other hand, colors that appear strong in the reflected light correspond to wavelengths for which the path length difference leads to constructive interference.

These colors will be reinforced and appear more vibrant. In this case, colors with a path length difference close to an integer multiple of their wavelengths will be enhanced.

The soap bubble will appear most strongly colored at wavelengths that satisfy the equation:

2n * (λ/2) = 680 x 10^-9 m

For n = 1: λ = (680 x 10^-9 m

a. Calculation of equivalent units of production for both direct materials and conversion for the forming department:
Equivalent units of production = Units completed during the period + (Ending work in process inventory * Degree of completion)
Direct materials:
Equivalent units of production = 45,000 + (5,000 * 50%) = 47,500 units

Conversion costs:
Equivalent units of production = 45,000 + (5,000 * 60%) = 48,000 units

b. Calculation of the cost per equivalent unit of production for both direct materials and conversion for the forming department:
Cost per equivalent unit of production = Total cost for the period / Equivalent units of production

Direct materials:
Cost per equivalent unit of production = $202,500 / 47,500 units = $4.26 per unit

Conversion costs:
Cost per equivalent unit of production = $189,000 / 48,000 units = $3.94 per unit

The subsequent current in the series RLC circuit is given by the equation: i(t) = I * cos(5t - Φ), where I is the amplitude of the current and Φ is the phase angle.

To find the subsequent current, we need to calculate the amplitude (I) and the phase angle (Φ) of the current.

First, let's calculate the resonant frequency (ω) of the circuit:

ω = 1 / √(LC) = 1 / √(10 * 10^(-2)) = 1 / √1 = 1 rad/s.

The applied voltage can be written as E(t) = E * cos(ωt), where E is the amplitude of the voltage.

Comparing this with the given voltage E(t) = 200 * cos(5t), we can equate the angular frequencies: ω = 5.

Now, let's find the impedance (Z) of the circuit:

Z = √(R^2 + (Xl - Xc)^2),

where R is the resistance, Xl is the inductive reactance, and Xc is the capacitive reactance.

R = 20 Ω

Xl = ωL = 1 * 10 = 10 Ω

Xc = 1 / (ωC) = 1 / (5 * 10^(-2)) = 20 Ω

Plugging in these values, we get:

Z = √(20^2 + (10 - 20)^2) = √(400 + 100) = √500 ≈ 22.36 Ω.

The amplitude of the current (I) can be calculated using Ohm's Law:

I = E / Z = 200 / 22.36 ≈ 8.94 A.

The phase angle (Φ) can be found using the relationship between resistance, inductive reactance, and capacitive reactance:

tan(Φ) = (Xl - Xc) / R = (10 - 20) / 20 = -0.5.

Therefore, Φ ≈ -0.464 rad.

The subsequent current in the series RLC circuit is given by i(t) = 8.94 * cos(5t + 0.464) A.

The equation that is most appropriate for finding the acceleration of the speedboat is Δv = aΔt, where Δv is the change in velocity, a is the acceleration, and Δt is the time it takes for the boat to change its velocity by Δv.

The equation is derived from the definition of acceleration, which is the rate of change of velocity with time. It is given by the formula: a = Δv / Δt, where Δv is the change in velocity and Δt is the time interval over which the change occurs.In this case, the speed of the boat increases uniformly from vi = 20.0 m/s to vf = 36.0 m/s in a distance of Δx = 2.00 × 102 m. To find the acceleration of the boat, we need to use the equation: Δv = aΔt, where Δv = vf - vi = 36.0 m/s - 20.0 m/s = 16.0 m/s and Δt = Δx / vavg,

where vavg is the average velocity of the boat over the distance Δx. We can calculate vavg as:vavg = (vi + vf) / 2 = (20.0 m/s + 36.0 m/s) / 2 = 28.0 m/sTherefore, Δt = Δx / vavg = (2.00 × 102 m) / (28.0 m/s) = 7.14 sSubstituting these values into the equation, we get:Δv = aΔt16.0 m/s = a(7.14 s)Solving for a, we get:a = Δv / Δt = 16.0 m/s / 7.14 s = 2.24 m/s²Therefore, the acceleration of the speedboat is 2.24 m/s².
