The ratio of boys to girls in the class was 2 to 3. If there were 18 girls in the class, how many students were in the class

provides steady-state operating data for a solar power plant that operates on a Rankine cycle with Refrigerant 134a as its worki

Vaselesa [24]

Answer:

hello some parts of your question is missing attached below is the missing part ( the required fig and table )

answer : The solar collector surface area = 7133 m^2

Explanation:

Given data :

Rate of energy input to the collectors from solar radiation = 0.3 kW/m^2

percentage of solar power absorbed by refrigerant = 60%

Determine the solar collector surface area

The solar collector surface area = 7133 m^2

attached below is a detailed solution of the problem

A glass plate is subjected to a tensile stress of 40 MPa. If the specific surface energy is 0.3 J/m2 and the modulus of elastici

Alika [10]

Answer:

The maximum length of a surface flaw is 8.24 μm

8.24 μm

Explanation:

Given that:

The modulus of elasticity E = 69 GPa

The specific surface energy $\delta_s$ = 0.3 J/m²

The length of the surface flaw "a" = ??

From the theory of the brittle fracture;

$\sigma _c = \bigg ( \dfrac{2E \delta_s}{\pi a} \bigg )^{1/2}$

Making a the subject of the formula; we have:

$a = \bigg ( \dfrac{2 \times E \times \delta_s}{\pi \sigma _c ^2} \bigg )$

$a= \bigg ( \dfrac{2 \times 69*10^9 \times 0.3}{\pi (40*10^6)^2} \bigg )$

a = 8.24 × 10⁻⁶ m

a = 8.24 μm

Thus; the maximum length of a surface flaw is 8.24 μm

Column arrays: Transpose a row array Construct a row array countValues with elements 1 to endValue, using the double colon opera

White raven [17]

Answer:

Matlab code with step by step explanation and output results are given below

Explanation:

We have to construct a Matlab function that creates a row vector "countValues" with elements 1 to endValue. That means it starts from 1 and ends at the value provided by the user (endValue).

function countValues = CreateArray(endValue)

% Here we construct a row vector countValues from 1:endValue

countValues = 1:endValue;

% then we transpose this row vector into column vector

countValues = countValues';

end

Output:

Calling this function with the endValue=11 returns following output

CreateArray(11)

ans =
