answer : Ac = 5° , A\(_{f}\) = 2.5°

Explanation:

Bandgap energy for material A = 0.90 eV

Bandgap energy for material B = 1.10 eV

Calculate the ratio of ni for Material B to Material B

Total derivation ( d ) = d1 + d2

 d = A\(_{c}\) ( μ\(_{c}\) - 1 ) + A\(_{f}\) ( μ\(_{f}\) - 1 )  ---- ( 1 )

where : d = 1° , μ\(_{c}\) = 1.5 , μ\(_{f}\) = 1.6

Input values into equation 1 above

1° = 0.5Ac + 0.6Af  ---- ( 2 )

also d = d1 [ 1 - w/ w1 ] ------ ( 3 )

∴ d = Ac ( μ\(_{c}\) - 1 ) ( 1 - w/w1 )

  1° = Ac ( 1.5 - 1 ) ( 1 - 0.06/0.1 ) --- ( 4 )

resolving  equation ( 4 )

Ac = 5°

resolving equation ( 2 )

A\(_{f}\) = 2.5°

Answer:

± 0.003 ft

Explanation:

Since our distance is 10,000 ft and we need to use a full tape measure of 100 ft. We find that 10,000 = 100 × 100.

Let L' = our distance and L = our tape measure

So, L' = 100L

Now by error determination ΔL' = 100ΔL

Now ΔL' = ± 0.30 ft

ΔL = ΔL'/100

= ± 0.30 ft/100

= ± 0.003 ft

So, the maxim error per tape is ± 0.003 ft

The reinforcement must be stored in such a manner as to prevent: deterioration and corrosion.

Concrete reinforcement is accomplished by inserting deformed steel bars or welded wire fabric inside newly cast concrete. The goal of reinforcing is to give strength to concrete where it is required.

All exposed reinforcing surfaces should be carefully cleaned of loose mortar, corrosion, and other pollutants. To prevent overbuilding and limit bond development loss at rebar deformations, the high-performance protective coating should be placed at a thickness of 305 microns.

2) The law of thermodynamics makes us to understand that when heat/energy passes through a system, the systems internal energy changes with respect to the conservation of energy law. That is energy lost = energy gained. Typically, ice would melt in a cup of hot tea because of the thermal energy in the molecules of the hot tea. When you heat a material, you are adding thermal kinetic energy to its molecules and usually raising its temperature. The temperature of the ice raises due to the kinetic energy added to it and it melts to water.

3) The theory of systems view the world as a complex system of interconnected parts. If we consider the society; (financial systems, political systems, etc) we will agree that they individually have their own components and it's the summation of this components that makes the system, this implies that system thinking could be applicable in this kinda of systems as long as they are made up of components.

Paleobotany is simply referred to as the branch of botany that deals with the study of the fossils of plants and the identification of the remains of plants.

Paleobotany lays emphasis on the fossils of plant fossils, such as fungi, algae, ferns, etc. It should be noted that paleobotany is vital as it helps scientists understand the evolution of plants. This is vital in determining the classes to which certain plants belongs.

Explanation:

mass=19kg

density=800kg/m³

volume=?

as we know that

density=mass/volume

density×volume=mass

volume=mass/density

putting the values

volume=19kg/800kg/m³

so volume=0.02375≈0.02m³

In December 2009, an approach was proposed to incorporate a nonlinear equation of state into a damage model for high-velocity impact analysis of brittle materials.

When studying the behavior of brittle materials under high-velocity impacts, it is essential to account for the nonlinearity of the material response. Traditional linear models may not accurately capture the complex behavior observed during these dynamic events.

By incorporating a nonlinear equation of state into the damage model, researchers aimed to improve the accuracy of predictions and better simulate the material's response under high-velocity impacts. The nonlinear equation of state describes the relationship between stress, strain, and other material properties, taking into account the nonlinear behavior exhibited by brittle materials.

This enhanced damage model allows for a more realistic representation of the material's response during high-velocity impacts, considering factors such as energy dissipation, fracture patterns, and failure modes. The incorporation of a nonlinear equation of state provides a more comprehensive understanding of the complex phenomena involved in the impact analysis of brittle materials, leading to improved predictions and design considerations for such scenarios.

Answer:

(a) Precipitation hardening - 1, 2, 4

(b) Dispersion strengthening - 1, 3, 5

Explanation:

The correct options for each are shown as follows:

Precipitation hardening

From the first statement; Dislocation movement is limited by precipitated particles. This resulted in an expansion in hardness and rigidity. Precipitates particles are separated out from the framework after heat treatment.

The aging process occurs in the second statement; because it speaks volumes on how heated solutions are treated with alloys above raised elevated temperature. As such when aging increases, there exists a decrease in the hardness of the alloy.

Also, for the third option for precipitation hardening; This cycle includes the application of heat the alloy (amalgam) to a raised temperature, maintaining such temperature for an extended period of time. This temperature relies upon alloying components. e.g. Heating of steel underneath eutectic temperature. Subsequent to heating, the alloy is extinguished and immersed in water.

Dispersion strengthening

Here: The effect of hearting is not significant to the hardness of alloys hardening by the method in statement 3.

In statement 5: The process only involves the dispersion of particles and not the application of heat.

The 74ls122 one-shot is a type of digital integrated circuit that generates a single pulse when triggered. In this case, we need to generate an output pulse of 3 ms duration using this one-shot.

To determine the value of external resistance required, we need to use the formula for the time period of the one-shot:

T = 1.1 x R x C

where T is the time period of the one-shot, R is the external resistance, and C is the capacitance. Since we want the output pulse to be 3 ms, we can convert this to seconds:

T = 0.003 s

Substituting this value into the formula, we get:

0.003 = 1.1 x R x 50000 x 10^-12

Simplifying this equation, we get:

R = 54.55 kohms

Therefore, an external resistance of 54.55 kohms is required to generate an output pulse of 3 ms duration using a 74ls122 one-shot and a capacitor of 50,000 pf.

In summary, we have determined the value of external resistance required to generate an output pulse of 3 ms duration using a 74ls122 one-shot and a capacitor of 50,000 pf. The value of external resistance is 54.55 kohms, which can be calculated using the formula T = 1.1 x R x C.
