Despite their political and strategic differences, the United States and the Soviet Union strongly resembled one another in 1945 in that they were both major global powers with significant military capabilities and a desire to exert influence over other nations.
Military capability is often referred to in terms of low, medium and high, although this usually refers to the type, quantity and sophistication of technology being used in combat operations, and the severity of threat to security of the state.
Maintaining military capability requires modernisation of military technology, particularly prevalent in Europe since the Middle Ages due to the arms race that commenced with the introduction of artillery and later firearms into warfare.
Additionally, both countries were undergoing significant economic and social changes, with the United States experiencing a post-war economic boom and the Soviet Union rapidly industrializing under Stalin's five-year plans. However, their different ideologies and visions for the future would eventually lead to the Cold War and decades of tense relations.

what proportion of observed variation in removal efficiency can be attributed to the model relationship?
The proportion of observed variation in removal efficiency that can be attributed to the model relationship can be determined by calculating the coefficient of determination, also known as R-squared (R^2) value.
Here's a step-by-step explanation:
1. Obtain data on the observed removal efficiency and the corresponding model predictions.
2. Calculate the mean (average) of the observed removal efficiency values.
3. Calculate the total sum of squares (SST), which represents the total variation in removal efficiency. To do this, find the difference between each observed value and the mean, square the differences, and sum them up.
4. Calculate the sum of squares due to regression (SSR), which represents the variation explained by the model. To do this, find the difference between each predicted value and the mean, square the differences, and sum them up.
5. Calculate R^2 value by dividing SSR by SST: R^2 = SSR/SST.
The R^2 value represents the proportion of observed variation in removal efficiency that can be attributed to the model relationship. A value of 1 indicates that the model explains 100% of the variation, while a value of 0 indicates that the model explains none of the variation.

Describe the various methods that can be used to conduct direct observational research with and without intervention. Which of these methods give researchers the most control? The least?
Direct observational research involves directly observing and recording behavior in real-time, as it occurs naturally, with or without researcher intervention.
Some of the methods used in direct observational research without intervention include:
⇒Naturalistic observation: This method involves observing behavior in a natural setting, without interfering or manipulating the situation. The researcher simply observes and records behavior as it occurs naturally, without attempting to change anything. This method provides a good representation of how people behave in real-life situations, but it lacks control over the variables that influence behavior.
⇒Participant observation: This method involves the researcher becoming part of the group being observed, and observing behavior from within the group. This can provide more detailed and nuanced information about behavior, but it can also be difficult to remain objective and avoid influencing the behavior being observed.
⇒Structured observation: This method involves observing behavior in a controlled environment, with specific instructions given to participants or observers. The researcher can control the variables that influence behavior to some extent, but this method may not reflect how people behave in real-life situations.

identify and explain two of the contextual perspectives on organizational behavior.
There are many contextual perspectives on organizational behavior, but two important ones are the contingency approach and the systems approach.
The contingency approach suggests that there is no single way to manage organizations that work best in all situations. Instead, managers must analyze each situation and choose the best management approach for that particular situation. The contingency approach emphasizes that different organizations, different departments within an organization, and different people within a department require different management styles and techniques.
The systems approach, on the other hand, views the organization as a complex system of interrelated and interdependent parts. This approach suggests that organizations are open systems, meaning that they interact with their environment and must adapt to changes in the environment to survive. The systems approach emphasizes the importance of understanding the relationships between different parts of the organization, and of designing the organization to be flexible and adaptable to changing circumstances.
Overall, both the contingency and systems approaches highlight the importance of understanding the unique context in which an organization operates, and of tailoring management strategies and practices to fit that context.

consider a solution initially containing 0.30 m of ch3nh2 mixed with 0.50 m of ch3nh3cl in water. what is the ph after the addition of 8 ml of 0.10 m naoh to 18.5 ml of this solution?
The pH of the solution after the addition of NaOH is approximately 11.57.
To solve this problem, we need to use the Henderson-Hasselbalch equation, which relates the pH of a solution to the concentration of its conjugate acid and base:
pH = pKa + log([A-]/[HA]),
where pKa is the acid dissociation constant of the weak acid (in this case, CH₃NH₂), [A-] is the concentration of the conjugate base (in this case, CH₃NH₂-), and [HA] is the concentration of the weak acid (in this case, CH₃NH₃+).
We can assume that the volume of the solution does not significantly change after the addition of the NaOH. Therefore, we can use the initial concentrations to calculate the concentrations after the addition of NaOH:
Initial [CH₃NH₂] = 0.30 M
Initial [CH₃NH₃+] = 0.50 M
[OH-] added = (0.10 M) x (8 mL / 26.5 mL) = 0.030 M
Since NaOH is a strong base, it will react completely with CH₃NH₂ to form CH₃NH₂- and water:
CH₃NH₂+ OH- -> CH₃NH₂ + H₂O
The amount of CH₃NH2 that is converted to CH₃NH₂- can be calculated using the stoichiometry of the reaction:
moles CH₃NH₂ = (0.30 M) x (26.5 mL / 1000 mL) = 0.00795 moles
moles OH- = (0.030 M) x (8 mL / 1000 mL) = 0.00024 moles
moles CH₃NH₂ converted = 0.00024 moles
After the reaction, the concentrations of CH₃NH₂and CH₃NH₂- will be:
[CH₃NH₂] = (0.00795 - 0.00024) moles / (26.5 mL / 1000 mL) = 0.290 M
[CH₃NH₂-] = 0.00024 moles / (26.5 mL / 1000 mL) = 0.00906 M
To calculate the pH of the solution, we need to determine the pKa of CH₃NH₂ The pKa of CH₃NH₂is approximately 10.7. Using this value, we can plug in the concentrations of CH₃NH₂ and CH₃NH₂ into the Henderson-Hasselbalch equation:
pH = 10.7 + log([0.00906]/[0.290]) = 11.57
Therefore, the pH of the solution after the addition of NaOH is approximately 11.57.
