1. (‘JJ) uses a certain machine to produce carjacks. The machine cost the company $90,000 three years ago. The reduced ...

s ago. The reduced book value now stands at $60,000. A new model of the machine is currently available for $139,350. The new machine has a useful life of five years, at which time it will be sold for $20,000. Using the new machine, the expected unit sales of the car jacks would be 6,000 car jacks per annum. The estimated unit selling price is $35 for the first year. As a result of the COVID-19 pandemic in Singapore, JJ is experiencing labour shortage. JJ will have to transfer workers from another department to the new project. These workers earn a contribution of $2 per direct labour hour in their original department. The fixed overhead cost would be $2.20 per hour and this is expected to remain unchanged. JJ’s products are being sold to a distributor. The sales agreement allows the selling price to rise at the rate of 10 percent per year after the first year. The unit cost price, except for fixed costs, is expected to increase at the same rate as the selling price. Working capital requirements are expected to be $15,000 in the first and second years, increasing to $18,000 in the third year and is expected to remain at this level till the end of the project. All the amounts of working capital will be recovered at the time of project termination. The new project uses cutting-edge technology and so enjoys a tax holiday from the authorities. The drawback of using this high-risk approach is that the new project requires a minimum return of 27 percent per annum. Required: Identify the relevant cash flows for the decision as to whether JJ should proceed to purchase the new machine. Note: To show all workings with accompanying explanations.

2.I need help in summarizing this article: The air we inhale could be changing our conduct in manners we are just ...

we are just barely starting to understand.In the future, police and wrongdoing counteraction units may start to screen the degrees of contamination in their urban communities, and convey assets to the spaces where contamination is heaviest on guaranteed day.This may seem like the plot of a sci-fi film, however ongoing discoveries recommend that this likely could be a beneficial practice.Why? Arising contemplates show that air contamination is connected to disabled judgment, emotional well-being issues, more unfortunate execution in school and most worryingly maybe, more elevated levels of crime.These discoveries are largely the really disturbing, given that more than a big part of the total populace now live in metropolitan conditions – and a greater amount of us are going in blocked regions than any time in recent memory. However, perhaps, he thought, there could be other unfavorable impacts on our lives.To start with, he led an investigation seeing whether air contamination had an impact in psychological performance.Roth and his group saw understudies taking tests on various days – and furthermore estimated how much contamination was noticeable all around on those given days. Indeed, even a couple days prior and a couple of days after, they discovered no impact – it's truly upon the arrival of the test that the grade diminished altogether. To decide the drawn out impacts, Roth followed up to perceive what affect this had eight to 10 years after the fact. In this way, he daid that regardless of whether it's a present moment impact of air contamination, on the off chance that it happens in a basic period of life it truly can have a drawn out impact. In 2018 examination, his group broke down two years of wrongdoing information from more than 600 of London's discretionary wards, and tracked down that more insignificant violations happened on the most dirtied days, in both rich and poor areas.Although we ought to be careful about reaching determinations about connections, for example, these, the creators have seen some proof that there is a causal link.Wherever the haze of contamination ventures, wrongdoing increments. As a feature of a similar report, they thought about unmistakable regions over the long haul, just as following degrees of contamination over the long haul. This implies that an intercession at an early age ought to be a priority.Exposure to different poisons can cause aggravation in the cerebrum. There are numerous potential components that may clarify how air contamination influences our morality.Lu, for example, has shown that the simple considered contamination can impact our brain science through its negative associations.Naturally, the scientists couldn't truly uncover members with contamination, so they took the following best (morally supported) venture so they asked them to truly envision living around here, and how they would feel and how their life would be living in this climate, to make them mentally experience air contamination versus a perfect climate. He tracked down that the member's tension expanded, and they became more self-focussed – two reactions that could increment forceful and flippant practices. Along these lines, by raising people groups' tension, air contamination can detrimentally affect conduct. at the point when we are restless we are bound to punch somebody in the face, than when we are quiet. Lead analyst Joanne Newbury, from King's College London, says she can't however guarantee that her outcomes are causal, yet the discoveries are in accordance with different investigations proposing a interface between air contamination and psychological wellness. "It adds to confirm connecting air contamination to actual medical conditions and air contamination connect to dementia.

4.Directions: You are part of a fireworks crew assembling a local fireworks display. There are two parts to the fireworks platforms: ...

rts to the fireworks platforms: one part is on the ground and the other part is on top of a building. You are going to graph all of your results on one coordinate plane. Make sure to label each graph with its equation. Use the following equations to assist with this assignment. • The function for objects dropped from a height where t is the time in seconds, h is the height in feet at time it t, and 0 h is the initial height is 2 0 ht t h ( ) 16 =− + . • The function for objects that are launched where t is the time in seconds, h is the height in feet at time t, 0 h is the initial height, and 0 v is the initial velocity in feet per second is 2 0 0 ht t vt h ( ) 16 =− + + . Select the link below to access centimeter grid paper for your portfolio. Centimeter Grid Paper Task 1 First, conduct some research to help you with later portions of this portfolio assessment. • Find a local building and estimate its height. How tall do you think the building is? • Use the Internet to find some initial velocities for different types of fireworks. What are some of the initial velocities that you found? Task 2 Respond to the following items. 1. While setting up a fireworks display, you have a tool at the top of the building and need to drop it to a coworker below. a. How long will it take the tool to fall to the ground? (Hint: use the first equation that you were given above, 2 0 ht t h ( ) 16 =− + . For the building’s height, use the height of the building that you estimated in Task 1.) b. Draw a graph that represents the path of this tool falling to the ground. Be sure to label your axes with a title and a scale. Your graph should show the height of the tool, h, after t seconds have passed. Label this line “Tool”.
