Its a video of a glider pushed forward and going back due to a fan blowing of the opposite direction of being pushed.

After watching this video, Blake, a student in an introductory physics class, makes the following claim:

The acceleration and velocity of the glider are both momentarily zero when the glider changes direction. The velocity of the glider must be zero for an instant when the glider changes direction. Because the velocity is zero, the acceleration must also be zero.

Respond to Blake's claim. Which parts, if any do you agree with, and which parts do you not agree with? To support your response, use evidence from your experience, or from the videos in this activity.

​Treck Co. expects to pay £350,000 in one month for its imports from Northern Ireland. It also expects to receive £325,000 for its exports to Scotland in one month. Treck Co. estimates the standard deviation of monthly percentage changes of the pound to be 2% percent over the last 3 years. Assume that these percentage changes are normally distributed. Using the value-at-risk (VaR) method based on a 95 percent confidence level, what is the maximum one-month loss in dollars if the expected percentage change of the pound during next month is -2 percent? The current spot rate of the pound (before considering the maximum one-month loss) is $1.38.

“The acceleration can be credited to the urgency to support employees working remotely so the business can run as smoothly as possible and provide a superior employee experience amidst the panic and uncertainty. With businesses struggling to survive in the face of, what is likely, one of the harshest recessions to date, it’s vital to understand the changes that will be brought about by this global pandemic. These changes will be facilitated by newer technologies such as Artificial Intelligence (AI), Internet of Things (IoT), and automation, and force companies to rethink their existing structures and guidelines”

In the context of the above statement, critically discuss the Human Resource Planning cycle that any organisation of your choice can follow in developing a Human Resource Plan for its organization. (25)

You were ecstatic when you heard the news that your cousins Archie came into a large inheritance last year and invested the entire amount in the common stock of commonwealth Brewery, a large manufacturing of liquid drinking products. Subsequently he has been very interested in the company and watches it closely. Recently, the Nassau Guardian carried a story about major strategic changes at the company including massive layoffs and business realignments. Archie was devastated and was dumb-founded. He does not understand how the firm could have made such changes without the knowledge and approval of its stockholders. Write a brief letter to Archie explaining how things really work.

We are evaluating a project that costs $500,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 50,000 units per year. Price per unit is $40, variable cost per unit is $25, and fixed costs are $600,000 per year. The tax rate is 35 percent, and we require a return of 12 percent on this project.

a. Calculate the accounting break-even point.

b-1 Calculate the base-case cash flow and NPV.

b-2 What is the sensitivity of NPV to changes in the sales figure?

c. What is the sensitivity of OCF to changes in the variable cost figure?

using the same software process model is not necessarily the best way to
engineer all projects. Based on what you studied, answer the following:

1. Differentiate between processes and methodologies.

2. Determine a suitable process model for the following projects

a) An enterprise software system where the stakeholders do not well understand requirements. Thus, requirements are expected to be extremely changeable due to external changes, changing expectations, changes in the budget and the rapid change in technology.

b) An online medical store where users are not determined about their requirements. However, cost, errors avoidance and implementation have a higher priority over the functionality, which can be added in later versions.

a steam power plant operates on a superheated rankine cycle where steam at 10kg/s entering the turbine at 5MPa and 375 degree celcius and leaving the turbine at saturated vapor at pressure 100 times less then initial. If the compressor efficiency is 85% ,

I) sketch the cycle of T-s diagram

ii) calculate the temperature and pressure for all points in the cycle

iii) calculate the compressor work

iv) calculate the turbine work and turbine efficiency

v.) calculate the thermal efficiency of the cycle

vi) if the efficiency of turbine and compressor is 100%;

a) is there any changes in temperature of the steam leaving the compressor and turbine? why?

b) Is there is any changes in the thermal efficiency of the cycle? prove the statement

Sara earns $200 in the first period and $100 in the second period. She lives in the two-period Fisher model of consumption. Therefore, she can borrow or lend at the interest rate r. considering the two-period Fisher’s model,

a) Write down her intertemporal budget constraint.

b) Assume that She is consuming 150 in the first-period and 160 in the second-period. What is the interest rate?

c) What will happen to Sara’s consumption if the interest rate changes to r=10%. Support your interpretation with a related graph.

d) What will happen to Sara’s consumption if interest rate changes to r=30%. Support your interpretation with a related graph.
