Zinc and cadmium are not transition metals because their d-orbitals are completely filled, and they do not have variable oxidation states.

Hence option  D is correct.

Transition metals are elements that occupy the d-block of the periodic table, characterized by their ability to form stable complex ions with variable oxidation states.

Zinc and cadmium, on the other hand, are not transition metals because they do not have partially filled d-orbitals in their ground state electron configuration.

Zinc has the electron configuration [Ar]3d10 4s2 and cadmium has [Kr]4d10 5s2, which means that their d-orbitals are completely filled. Although both elements can form complex ions, they do not have variable oxidation states like other transition metals.

Instead, they usually show a +2 oxidation state.

1. The number on the top crosshair represents the vertical distance from the center of the crosshair to the top of the target.

The number on the top crosshair provides information about the vertical alignment of the scope. It indicates the amount of vertical adjustment needed to bring the point of aim to the desired point of impact. By adjusting the elevation turret on the scope, you can move the crosshair up or down to compensate for bullet drop or to zero the rifle at a specific distance. The number on the top crosshair is typically expressed in minutes of angle (MOA) or milliradians (mils), depending on the scope. These measurements allow for precise adjustments to ensure accurate shooting at different distances. By referring to the number on the top crosshair, you can make the necessary adjustments to align your shots with the target.

The magnitude and direction of the resultant of the given forces using Cartesian vector notation method are R = 942.6N at 246.9°.

To solve this problem using Cartesian vector notation method, we need to find the x- and y-components of each force, add up the components separately, and then find the magnitude and direction of the resultant vector.

First, let's find the x- and y-components of each force:

F1 = 800N at 45°

Fx1 = F1 * cos(45°) = 800N * cos(45°) = 565.7N

Fy1 = F1 * sin(45°) = 800N * sin(45°) = 565.7N

F2 = 600N at 30°

Fx2 = F2 * cos(30°) = 600N * cos(30°) = 519.6N

Fy2 = F2 * sin(30°) = 600N * sin(30°) = 300N

F3 = 700N at 180° (horizontal direction)

Fx3 = F3 = -700N

Fy3 = 0N

Next, let's add up the x- and y-components of the three forces:

Rx = Fx1 + Fx2 + Fx3 = 565.7N + 519.6N - 700N = 385.3N

Ry = Fy1 + Fy2 + Fy3 = 565.7N + 300N + 0N = 865.7N

The magnitude of the resultant vector R is:

|R| = sqrt(Rx^2 + Ry^2) = sqrt(385.3N^2 + 865.7N^2) = 942.6N

The direction of the resultant vector R is:

theta = arctan(Ry/Rx) = arctan(865.7N/385.3N) = 66.9°

However, we need to adjust the angle by adding 180° because the vector points into the third quadrant:

theta = 66.9° + 180° = 246.9°

Therefore, the magnitude and direction of the resultant of the given forces using Cartesian vector notation method are R = 942.6N at 246.9°.

The rate of heat transfer by the air conditioner using constant specific heat of 1.004kj/kg.K is 15.06 kW.

Rate of heat transfer is the power rating of the machine.

Work done and changes in potential and kinetic energy are neglected since it is a steady state process.

The specific heat in terms of specific heat capacity and temperature change is given as:

\(q_{out} = Cp(Ti - Te)\)

\(q_{out} = 1.004(30 - 10) = 20.08 kJ/kg \\ \)

The rate of heat transfer, is then determined as follows:

Qout = 0.75 × 20.08 = 15.06 kW

Therefore, the rate of heat transfer by the air conditioner is 15.06 kW.

Answer:

using standardized parts

Explanation:

The given alloy consists of 45% lead (Pb) and 55% magnesium (Mg). When this alloy is rapidly quenched to room temperature, the high temperature microstructure is preserved. This microstructure consists of two phases: α (alpha) phase and Mg2Pb. The mass fractions of these two phases are 0.65 and 0.35, respectively. We need to determine the approximate temperature from which the alloy was quenched.

Therefore, the temperature from which the alloy was quenched must be greater than 150°C. Since the high temperature microstructure was preserved during quenching, the quenching temperature must also be less than the temperature at which the Mg2Pb phase disappears completely (i.e., the eutectic temperature).From the phase diagram, we can see that the eutectic temperature is approximately 371°C. Therefore, the approximate temperature from which the alloy was quenched is between 150°C and 371°C.

In this definition, the `BstWithHeight` class extends the existing `Bst` class, allowing it to inherit all of its properties and methods. The `height()` method is then added to this new class, which will calculate the height of the binary search tree when implemented.

To define a new class named bstwithheight that extends bst with the following method public int height(), you can start by declaring your class and extending the bst class:

public class bstwithheight extends bst {

Then, you can define your new method, height(), within the class. This method will calculate the height of the tree rooted at a given node by recursively traversing through its left and right subtrees and returning the maximum height:

public int height() {
   return height(root);
}

private int height(Node node) {
   if (node == null) {
       return -1;
   }
   int leftHeight = height(node.left);
   int rightHeight = height(node.right);
   return Math.max(leftHeight, rightHeight) + 1;
}

In this implementation, the height() method calls the private helper method, height(), which takes in a node as an argument. If the node is null, it returns -1 as the height. Otherwise, it recursively calls itself on the left and right subtrees of the node and returns the maximum height of the two subtrees, plus one to account for the current node.

With this implementation, you can now use the bstwithheight class to create binary search trees and calculate their heights using the height() method.

Today's supply chain management (SCM) systems are designed to extend beyond the traditional boundaries of an organization's four walls to include suppliers, customers, and other external stakeholders in the end-to-end value chain.

The goal of this extended SCM approach is to achieve better collaboration, visibility, and agility in the supply chain, leading to improved performance, reduced costs, and increased customer satisfaction.

With the rise of globalization and the increasing complexity of supply chains, it has become more important than ever to have end-to-end visibility and control over the supply chain. SCM systems that incorporate external stakeholders can help to achieve this goal by providing real-time information and collaboration tools to all parties involved in the supply chain. This enables more accurate forecasting, better risk management, and improved responsiveness to changes in demand or supply. By extending the SCM system beyond the organization's four walls, businesses can achieve a more holistic approach to supply chain management that can drive greater value for all stakeholders involved.

COP = 4.846

Explanation:

From the table A-11 i attached, we can find the entropy for the state 1 at -12°C.

h1 = 243.3 KJ/Kg

s1 = 0.93911 KJ/Kg.K

From table A-12 attached we can do the same for states 3 and 4 but just enthalpy at 800 KPa.

h3 = h4 = hf = 95.47 KJ/Kg

For state 2, we can calculate the enthalpy from table A-13 attached using interpolation at 800 KPa and the condition s2 = s1. We have;

h2 = 273.81 KJ/Kg

The power would be determined from the energy balance in state 1-2 where the mass flow rate will be expressed through the energy balance in state 4-1.

W' = m'(h2 - h1)

W' = Q'_L((h2 - h1)/(h1 - h4))

Where Q'_L = 150 kW

Plugging in the relevant values, we have;

W' = 150((273.81 - 243.3)/(243.3 - 95.46))

W' = 30.956 Kw

Formula foe COP is;

COP = Q'_L/W'

COP = 150/30.956

COP = 4.846
