To calculate Young's modulus for this material, we first need to understand the relationship between stress and strain in the elastic region. According to Hooke's Law, stress is proportional to strain within the elastic limit.

This means that we can use the following equation to calculate Young's modulus: Young's modulus (E) = stress/strain In this case, the stress is 257 MPa and the strain is 0.18 mm/mm. Therefore: E = 257 MPa / 0.18 mm/mm E = 1428.9 MPa Rounding to the nearest whole number, Young's modulus for this material is approximately 1429 MPa. It's worth noting that this calculation assumes that the elastic region extends directly to zero stress and zero strain from the given point. In reality, the elastic region may have a non-linear relationship between stress and strain, and the material may exhibit some degree of plastic deformation before reaching zero stress. However, this calculation provides a good estimate of Young's modulus for the given conditions.

No, the efficiency of a completely reversible heat engine cannot be doubled by simply doubling the temperature of the energy source.

The efficiency of a reversible heat engine is given by the formula:
Efficiency = 1 - (Tc/Th)
where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir.
Doubling the temperature of the energy source (Th) will not double the efficiency because the relationship is not linear. However, increasing the temperature of the hot reservoir will generally improve the efficiency of the heat engine, but it will not be doubled.

What is a dashboard?

A dashboard is an information management tool used to track KPIs, metrics, and key data points that are relevant to your business, department, or a specific process. Dashboards aggregate and visualize data from multiple sources, such as databases, locally hosted files, and web services. Dashboards allow you to monitor your business performance by displaying historical trends, actionable data, and real-time information.

Dashboards actually take their name from automobile dashboards and they are used in much the same way. For the sake of an analogy, let’s look at a car. There may be hundreds of processes that impact the performance of your vehicle if you look under the hood. Your car’s dashboard summarizes this using visualizations so you can focus on what matters most: safely driving your vehicle.

For businesses, there are hundreds of processes that impact your performance if you look ‘under the hood’, so to speak. And with a wealth of data made available these days, managing and extracting value from it can be difficult. Simplifying data analysis and distribution through tools like dashboards is a way to help businesses rev their engines and make smarter, better, faster data-driven decisions.

And a well designed dashboard levels up your approach to information management. Everyone in the business, regardless of role, has questions about your company performance, whether it be campaign performance, new wins, or churn rate. Dashboards bring everyone (and your metrics) together in one place to answer these questions.

Explanation:

The sample of 81 students was selected with a mean score of 90, this illustrates an example of a right tailed one sample z test.

From the information given, the teacher claims that the mean score of students in his class is greater than 82 with a standard deviation of 20. In this case, the right tailed one sample z test is used.

The z value will be:

= (90 - 82)/20/✓81

= 3.6

Since 3.6 > 1.645, the null hypothesis will be rejected as there's enough evidence to support the teacher's claim.

When an online medicine shop claims that the mean delivery time for medicines is less than 120 minutes with a standard deviation of 30 minutes, the left tailed one sample test is used.

The z value will be:

= (100 - 120)/(30/✓49)

= -4.66

The null hypothesis is rejected as there is enough evidence to support the claim of the medicine shop.

The weight of fumes produced by one welder working with an FCAW wire in a semi-automatic process for one year of operation is 28,800 grams.

The fume generation rate of a Flux-Cored Arc Welding (FCAW) wire is 1 g/min, we'll need to consider the working duty cycle of a welder in a semi-automatic process for one year to calculate the weight of fumes produced.

Assuming a typical working duty cycle for semi-automatic welding processes is 25%, and considering an 8-hour workday with 240 working days in a year, we can calculate the total fume generation as follows:

- Daily welding time = 8 hours/day × 60 minutes/hour × 25% duty cycle = 120 minutes/day
- Annual welding time = 120 minutes/day × 240 days/year = 28,800 minutes/year
- Annual fume generation = 28,800 minutes/year × 1 g/min = 28,800 grams/year

The java code can cause a compilation error running in a multithreading environment. One of the reason could be the variable "balance" is not declared as volatile, so there is no guarantee that the code will correctly set the balance and return the correct boolean value after a withdrawal.

Also, the java compiler could alerts an error when the return instruction is inside a cyclic structure and also when it is inside a conditional structure as it is in this case.

Answer: maximum length of the nanowire is 510 nm

Explanation:

From the table of 'Thermo physical properties of selected nonmetallic solids at At T = 1500 K

Thermal conductivity of silicon carbide k = 30 W/m.K

Diameter of silicon carbide nanowire, D = 15 x 10⁻⁹ m  

lets consider the equation for the value of m

m = ( (hP/kAc)^1/2 )  = ( (4h/kD)^1/2 )  

m =  ( ((4 × 10⁵)/(30×15×10⁻⁹ ))^1/2 ) = 942809.04    

now lets find the value of h/mk    

h/mk = 10⁵ / ( 942809.04 × 30) =  0.00353

lets consider the value θ/θb by using the equation

θ/θb = (T - T∞) / (T - T∞)

θ/θb =  (3000 - 8000) / (2400 - 8000)

= 0.893

the temperature distribution at steady-state is expressed as;

θ/θb = [ cosh m(L - x) + ( h/mk) sinh m (L - x)]   / [cosh mL+  (h/mk) sinh mL]

θ/θb = [ cosh m(L - L) + ( h/mk) sinh m (L - L)]   / [cosh mL+  (h/mk) sinh mL]

θ/θb = [ 1 ]  / [cosh mL+  (h/mk) sinh mL]

so we substitute

0.893 =  [ 1 ]  / [cosh (942809.04 × L) +  (0.00353) sinh (942809.04 × L)]

L = 510 × 10⁻⁹m

L = 510 nm

therefore maximum length of the nanowire is 510 nm

Answer:

a. True

Explanation:

The study of fluids in a state of rest or in motion and the forces involved in it is called fluid mechanics. Fluid mechanics has a wide range of applications in the field of mechanical engineering as well as civil engineering.

When we study the flow of fluid between any two flat plates that is indefinitely flat and is parallel, the flow of the fluid is known as plane Poiseulle flow. The profile of a plane Poiseulle flow is parabolic.

The velocity profile of a plane Poiseulle flow is :

\($\frac{u(y)}{U_{max}}=1-\left(\frac{2y}{h}\right)^2$\)

A 1 5 l0 lossless monopole with an input impedance of (20 j50) V is used in place of the quarter-wave monopole antenna from Problem 7.2.2. The total average power emitted is 13.86 /λ watts.

To determine the total average power radiated by the 1.5 λ lossless monopoles with an input impedance of (20 j50) V, we can use the formula:
P = (|V|^2 / 4R)
Where P is the power radiated, |V| is the magnitude of the voltage at the input impedance, and R is the radiation resistance of the antenna.
The radiation resistance of a monopole antenna is given by:
R = (2π)^2 * (h / λ)^2
Where h is the height of the antenna and λ is the wavelength of the operating frequency.
Assuming that the monopole is operating at its resonant frequency, we can find the height of the antenna using the formula:
h = λ / 4
Therefore, h = (1.5 * λ) / 4 = 0.375 λ
Substituting the values of h and λ in the formula for radiation resistance, we get:
R = (2π)^2 * (0.375)^2 * λ = 0.878 λ
Now, we can calculate the total average power radiated as follows:
P = (|V|^2 / 4R) = (|20 + j50|^2 / 4 * 0.878 λ) = 13.86 / λ watts
Therefore, the total average power radiated by the 1.5 λ lossless monopole with an input impedance of (20 j50) V is 13.86 / λ watts.

Refrigerant 134a enters the evaporator of a refrigeration system operating at a steady-state at -8oC and a quality of 20% at a velocity of 5 m/s. The mass flow rate of the refrigerant is 0.0594 kg/s  and the velocity at the exit is 24.191  m/s.

From the information given, we can use the properties table of refrigerant-134a to determine the values of the specific volume of saturated liquid and vapor at -8° C.

Now the specific volume of the refrigerant at the inlet of the evaporator can be computed by using the formula;

\(\mathbf{v_1=v_f +x(v_g-v_f)}\)

where;

\(\mathbf{v_1=0.0007570 +0.2(0.092438-0.0007570)}\)

\(\mathbf{v_1=0.0007570 +0.2(0.091681)}\)

\(\mathbf{v_1=0.0007570 +0.0183362}\)

v₁ = 0.0191 m³/kg

The density of the refrigerant at the inlet of the evaporator is:

\(\mathbf{\rho_1 = \dfrac{1}{v_1}}\)

\(\mathbf{\rho_1 = \dfrac{1}{0.0191} }\)

\(\mathbf{\rho_1={52.356 \ kg/m^3}}\)

However, the density of the  refrigerant at the outlet of the evaporator is:

\(\mathbf{\rho_g = \dfrac{1}{v_g}}\)

\(\mathbf{\rho_g= \dfrac{1}{0.0092438} }\)

\(\mathbf{\rho_g={10.818 \ kg/m^3}}\)

Recall that:

Now, the mass flow rate of the refrigerant can be computed by using the formula:

\(\mathbf{m = \rho_1 \Big[ \dfrac{\pi}{4} \times d^2 \Big] v_1 }\)

\(\mathbf{m = 52.356 \Big[ \dfrac{\pi}{4} \times (0.017)^2 \Big] 5 }\)

mass flow rate (m) = 0.0594 kg/s

Also, the velocity of the refrigerant at the exit of the evaporator is determined by using the formula:

\(\mathbf{m=\rho_2 \Big[ \dfrac{\pi}{4} \times d^2 \Big] v_2}\)

\(\mathbf{ 0.0594 kg/s = 10.818 \Big[ \dfrac{\pi}{4} \times (0.017)^2 \Big] v_2 }\)

\(\mathbf{v_2 = 24.191 \ m/s}\)

Therefore, we can conclude that the mass flow rate of the refrigerant is 0.0594 kg/s  and the velocity at the exit is 24.191  m/s.
