Identify the Burger's vector, slip plane(s), slip direction(s) and slip system in a given crystal.
Answers
The Burger's vector is a vector representing the magnitude and direction of the lattice distortion caused by a dislocation in a crystal. The slip plane(s) are the planes along which dislocations move, typically those with the highest atomic density.
The slip direction(s) are the directions along which atoms move during dislocation motion. The slip system is a combination of the slip plane and slip direction, and it describes the specific way in which dislocations move within a crystal.
In a crystal, dislocations cause lattice distortions, and the Burger's vector quantifies this distortion.
The slip plane(s) are important because they determine the ease of dislocation movement, affecting the crystal's mechanical properties. The slip direction(s) are the specific directions in which atoms rearrange during deformation. The slip system, as a combination of slip plane and slip direction, is essential for understanding the overall deformation behavior of a crystal.

What angle is needed between the direction of polarized light and the axis of a polarizing filter to reduce the intensity to 0.56 times the original intensity?
Answers
41.55° angle is needed between the direction of polarized light and the axis of a polarizing filter to reduce the intensity to 0.56 times the original intensity.
Assume that Io is the initial intensity and that is the angle between the polarizer and the filter axis.
After filtering, light has a 0.56 Io light intensity.
According to Malus's law, the amount of plane-polarized light that enters the analyzer is directly inversely proportional to the square of the cosine of the angle between the polarizer's plane and its transmission axis.
By applying the Malus law,
\(I = I_{0} Cos^{2}\)θ
\(0.56I_{0} = I_{0} Cos^{2}\)θ
\(0.56= Cos^{2}\)θ
θ = 41.55°
Therefore, 41.55° angle is needed between the direction of polarized light and the axis of a polarizing filter to reduce the intensity to 0.56 times the original intensity.

It is the same everywhere between the plated if any edge effect is ignored.b. It is a maximum near the negatively charged plate.c. It is a maximum near the positively charged plate.d. It is a maximum midway between the plates.
Answers
It is the same everywhere between the plates if any edge effect is ignored statements is true concerning the strength of the electric field between two oppositely charged parallel plates. The correct answer is Option A.
When two oppositely charged parallel plates are connected to a power source, an electric field is established between them. The electric field represents the force experienced by a positive test charge placed in the field. The correct answer is Option A.
In this case, the electric field between the plates is uniform, meaning it has the same magnitude and direction at all points between the plates. This is true if we ignore any edge effects, which can occur near the edges of the plates. If the plates are infinitely large, the electric field will be constant everywhere between them. However, in real-world situations with finite-sized plates, edge effects can cause the electric field to deviate slightly near the edges.

Pigments don't survive fossilization; even though we have fossil skin from dinosaurs, we don't know what color they were. But fossilization does preserve structure. Specimens from a rare cache of 50-million-year-old beetle fossils still show the microscopic layers that produced structural colors in the living creatures, and we can deduce the colors from an understanding of thin-film interference. One fossil showed 80 nm plates of fossilized chitin (modern samples have index of refraction n = 1.56) embedded in fossilized tissue (for which we can assume n = 1.33).
What is the longest wavelength for which there is constructive interference for reflections from opposite sides of the chitin layers?
Answers
Answer:
Explanation:
Light gets reflected by a medium of higher refractive index and then from a medium of lower refractive index a second time so there will be an additional phase difference of 180⁰.
For constructive interference in thin films the condition is as follows .
2μd = (2n+1) λ/2
where μ is 1.56 , d is 80 nm λ is wave length of ligh and n is an integer .
For longest wavelength , n = 0
λ = 4μd
= 4 x 1.56 x 80 nm
= 499.2 nm .

Answers
Distance can be defined as the amount of ground covered (traveled) by a physical object over a specific period of time and speed, regardless of its direction, starting point or ending point.
Mathematically, the distance traveled by a physical object can be calculated by using this formula:
Distance = speed × time
What is Dimitri's total distance?Dimitri's total distance is the sum of the distance he covered by moving from point A to B and then from B to C. Thus, his total distance is given by:
Total distance = AB + BC
Total distance = 18.1 + 13.3
Total distance = 31.4 feet.
What is the magnitude of Dimitri's displacement?The magnitude of Dimitri's displacement would be calculated by finding the difference in the position of the two point-to-point distances as follows:
Displacement = AB - BC
Displacement = 18.1 - 13.3
Displacement = 4.8 feet.

Two vehicles are traveling when they enter an intersection and crash and stick together. Both have a mass of 1,650 kg and both are traveling at 15 m/s. If one is headed North and the other is headed East, after the collision they end up traveling NE together at what speed (in m/s)? Please input your answer as a positive number with two decimal places.
Answers
Answer:
10.61 m/s
Explanation:
To find the final speed, we will use the conservation of momentum in each direction, so we can write the following equations:
\(\begin{gathered} p_{ix}=p_{fx} \\ m_1v_{1x}+m_2v_{2x}=(m_1+m_2)v_{fx} \\ \text{and} \\ p_{iy}=p_{fy} \\ m_1v_{1y}+m_2v_{2y}=(m_1+m_2)v_{fy} \end{gathered}\)Where m1 and m2 are the mass of the vehicles, v1 and v2 are their respective velocities in each direction, and Vfx and Vfy are the final velocities in each direction.
If one of the vehicles is headed north, its horizontal velocity Vx = 0 m/s. In the same way if the other is headed east, its vertical velocity Vy = 0m/s
Therefore, we can replace the values and solve the first equation as:
\(\begin{gathered} 1650(0)+1650(15)=(1650+1650)v_{fx} \\ 24750=3300v_{fx} \\ \frac{24750}{3300}=v_{fx} \\ 7.5m/s=v_{fx} \end{gathered}\)In the same way, we can solve the second equation as:
\(\begin{gathered} 1650(15)+1650(0)=(1650+1650)v_{fy} \\ 24750=3300v_{fy} \\ \frac{24750}{3300}=v_{fy} \\ 7.5m/s=v_{fy} \end{gathered}\)Now, we know that the vertical and horizontal speed was 7.5 m/s. So, we can calculate the final speed using the Pythagorean theorem as:
\(\begin{gathered} v=\sqrt[]{(v_{fx})^2+(v_{fy})^2} \\ v=\sqrt[]{(7.5)^2+(7.5)^2} \\ v=\sqrt[]{56.25+56.25} \\ v=\sqrt[]{112.5}=10.61\text{ m/s} \end{gathered}\)So, the speed after the collision was 10.61 m/s

N industrial customer with a three-phase, 480 V service entrance is running the following set of loads: • Two 15 HP, 89% efficient lathes, 0. 79 lagging power factor • One 7 ton heat pump' with a COP of 1. 9 and a 0. 95 lagging power factor • Two electric autoclaves, 30 BTU/h, 98% efficient, 0. 97 lagging PF One 25 kW high-intensity discharge (HID) lighting system, unity PF If the lighting system is replaced with a T8 fluorescent system with magnetic ballast that consumes 25% less than the previous system, but introduces a 0. 91 leading power factor, by how much does the service entrance current change? Consider the case when all systems are fully loaded. Consider the AC load under the new lighting regime. Use the NFPA 70 to determine the minimum allowed gauge of the service conductors. Feeder lines are copper, with a 60 °C temperature rating, contained within a raceway with an ambient temperature of 40 °C. Start with article 310. 15; state the specific article(s)/tables used to determine your answer
Answers
The minimum allowed gauge of the service conductors would be 1/0 AWG.
To calculate the current at the service entrance, we need to calculate the total power and power factor of the loads.
For the two lathes, the total power is 2 x 15 HP x 0.89 = 26.7 kW, and the power factor is 0.79 lagging. The apparent power (S) can be calculated as S = P / PF = 33.8 kVA.
For the heat pump, the total power is 7 ton x 12,000 BTU/ton x 0.2931 kW/BTU / 1.9 COP = 2.64 kW, and the power factor is 0.95 lagging. The apparent power can be calculated as S = P / PF = 2.78 kVA.
For the two autoclaves, the total power is 2 x 30 BTU/h x 0.98 / 3.412 BTU/kW = 17.5 kW, and the power factor is 0.97 lagging. The apparent power can be calculated as S = P / PF = 18.0 kVA.
For the HID lighting system, the power is 25 kW and the power factor is unity, so the apparent power is equal to the real power, S = P = 25 kVA.
The total apparent power for all loads is S_total = 33.8 + 2.78 + 18.0 + 25 = 79.58 kVA.
If the lighting system is replaced with a T8 fluorescent system that consumes 25% less power, the new power is 0.75 x 25 kW = 18.75 kW. The power factor is 0.91 leading, so the apparent power is S = P / PF = 20.6 kVA.
The new total apparent power for all loads is S_total = 33.8 + 2.78 + 18.0 + 20.6 = 75.18 kVA.
The current can be calculated using the formula I = S / (sqrt(3) x V), where V is the line voltage (480 V):
For the original loads, I_original = 79.58 kVA / (sqrt(3) x 480 V) = 96.4 A
For the new loads, I_new = 75.18 kVA / (sqrt(3) x 480 V) = 91.0 A
Therefore, the change in service entrance current is (91.0 - 96.4) A = -5.4 A.
To determine the minimum allowed gauge of the service conductors, we can use the table in NFPA 70 Article 310.15(B)(16) for 60°C rated conductors in raceways. Based on the calculated current of 96.4 A for the original loads, we would need a minimum of 2/0 AWG copper conductors. However, based on the calculated current of 91.0 A for the new loads, we would only need a minimum of 1/0 AWG copper conductors.
Therefore, the minimum allowed gauge of the service conductors would be 1/0 AWG.

let r be a total order on set s. prove that the width of r is 1, and the height of r is |s|.
Answers
The width of total order r on set s is 1, and its height is |s|.
To prove that the width of r is 1, we need to show that the distance between any two elements of s in the ordering r is at most 1. Since r is a total order, any two distinct elements of s are comparable, so the distance between them in r is either 0 or 1. If the distance were greater than 1, then there would exist an element x in s that lies strictly between the two elements, contradicting the assumption that r is a total order. Therefore, the width of r is 1.
To prove that the height of r is |s|, we need to show that there exists a chain (i.e., a totally ordered subset) of r with |s| elements. Since r is a total order, every element of s is comparable with every other element. Therefore, we can construct a chain of |s| elements by starting with any element of s and repeatedly adding the next-largest element until all elements have been included. This chain is totally ordered by the transitivity of r, and it has |s| elements by construction. Therefore, the height of r is |s|.
