ould be at least 500 words. The document should adhere to APA guidelines. Please state the question and then post your answer below the Question. Q1. How does marketing research help in the marketing planning process? Use a hypothetical business (e.g. a small sporting goods store, local hardware manufacturing small business, an independent publishing company, etc.) to discuss how market research helps in compiling market intelligence with regard to aspects such as product decisions, customer segmentation decisions, brand and pricing decisions, keeping stakeholders happy. Q2. NuVision Lens, a mail-order contact lens company has struggled to break even after being five years in the eyewear market. The company’s founders had thought that high demand would exist for mail-order supply as a low-cost alternative to purchasing contact lenses at optical outlets. However, the market share of NuVision continues to be much less than the retail stores. NuVision Lens has hired you as their marketing consultant. Outline the steps that you will take to formulate a problem statement and research objective on the above situation.

hin a free demo session as I have my answers, but just want to confirm them, that would be greatly appreciated. Question 1: A block of mass M = 0.10 kg is attached to one end of a spring with spring constant k = 100 N/m . The other end of the spring is attached to a fixed wall. The block is pushed against the spring, compressing it a distance x = 0.04 m . The block is then released from rest, and the block-spring system travels along a horizontal, rough track. Data collected from a motion detector are used to create a graph of the kinetic energy K and spring potential energy Us of the system as a function of the block's position as the spring expands. How can the student determine the amount of mechanical energy dissipated by friction as the spring expanded to its natural spring length? Question 2: The Atwood’s machine shown consists of two blocks connected by a light string that passes over a pulley of negligible mass and negligible friction. The blocks are released from rest, and m2 is greater than m1. Assume that the reference line of zero gravitational potential energy is the floor. Which of the following best represents the total gravitational potential energy U and total kinetic energy K of the block-block-Earth system as a function of the height h of block m1? Question 3: A 2 kg block is placed at the top of an incline and released from rest near Earth’s surface and unknown distance H above the ground. The angle θ between the ground and the incline is also unknown. Frictional forces between the block and the incline are considered to be negligible. The block eventually slides to the bottom of the incline after 0.75 s. The block’s velocity v as a function of time t is shown in the graph starting from the instant it is released. How could a student use the graph to determine the total energy of the block-Earth system? Question 4: A block slides across a flat, horizontal surface to the right. For each choice, the arrows represent velocity vectors of the block at successive intervals of time. Which of the following diagrams represents the situation in which the block loses kinetic energy?

bacteria). Obligatory anaerobes require absence of oxygen. You are researching how a facultative anaerobe transitions from anaerobic to aerobic respiration along the length of the human intestine (small and large intestine), where oxygen levels – and with them respiration - vary from atmospheric levels of oxygen (aerobic respiration) to no oxygen (anaerobic respiration). You grow cultures of a facultative anaerobic bacteria in flasks with different levels of oxygen that mimic the conditions in the 7.5m long human intestines and collect data on the growth rates of the bacteria (number of bacterial colonies) under the different conditions. Time food spends in the small intestine, 2.5m long, is 4 hrs. The time taken for food to pass through the entire length of the intestine is between 24 and 72 hrs. To determine oxygen levels in your flasks, you use the ratio of oxygen to nitrogen, which you vary between 0 (no oxygen) and 0.25 (atmospheric levels of oxygen). You assume that for conditions where r<0.01 your bacteria will be obligatorily anaerobic, and aerobic respiration will be observed from r=0.05. If the oxygen ratio goes from 0.25 to 0 over 7.5 m, and rO2 = 0.25 – 0.03x (x=distance along the intestine) describes the relationship between oxygen ration and the length of path travelled by the bacteria in the intestine, how long will it take bacteria to pass from the small into the large intestine? Explain how you arrived at your estimate.

In the neighbouring Nicolo’s Gym, the initial payment is 75 AUD higher than in Paolo’s Gym, however the monthly fee is lower at 30 AUD per month. (d) Determine the number of months it takes for the total cost to be less by attending Nicolo’s Gym in comparison to Paolo’s Gym.

van and Alex, have the same productivities: Sylvan is identical to Rajan, while Alex and Esther are identical. Esther and Rajan both engage in market work. Sylvan works full time at home, so only Alex works in the market. a) Given this information, which couple has the higher opportunity cost of home produced goods? Explain how you determined this. You can add a diagram if that helps, but you are not required to include one. b) Can you determine which couple has the higher utility? Explain why or why not. Suppose now that value of market production for both Alex and Esther increased to $12/per hour. c) Explain the change in the household joint production possibility frontier generated by this change. d) Explain what would happen to each couple’s choice of both household and market produced goods, using an analysis by means of income and substitution effects. e) What changes in time allocation for each couple that would be necessary to produce and consume this new bundle?

n, I completed parts A and B, but can't get C. We get all the answers to the questions but not how to get to the answer. The question is: Patrick changes velocity from 2.0 m/s North to 4.0 m/s South with an acceleration of 0.50 m/s/s South. (A) Determine how much time this process takes (ANSWER: 12 s). (B) Find his displacement (magnitude and direction) (ANSWER: 12 m South). (C) Find how much distance Patrick covered (ANSWER: 20 m). Another question I was having trouble with was this (I got part A but not parts B or C): Two cars are traveling along a straight line in the same direction, the lead car at 25.0 m/s and the other car at 30.0 m/s. At the moment the cars are 40.0 m apart, the lead driver applies the brakes, causing his car to have an acceleration of -2.00 m/s/s. (A) How long does it take for the lead car to stop? (ANSWER: 12.5 s). (B) Assuming that the chasing car brakes at the same time as the lead car, what must be the chasing car's minimum negative acceleration so as not to hit the lead car?

rmine size of piping for a water, wastewater, and stormwater system for an addition to a building on our campus. I am given maps of the existing conditions. I have calculated the new water demand which has to be used to determine the size of the pipes, though I am not completely sure if I did that right. I have a lot of information which I have compiled into a one drive file that I can share. I am able to help provide any information that is necessary since I am familiar with what the files contain. I have attached a document which explains everything that I need to do. I am able to use the existing network for the most part so routing of it should be easy. The part I am unsure about is determining the size of the pipes. For the water, I believe I can use mannings equation. For wastewater, I am unsure. For stormwater, I am to use the rational method and I have an excel tool which makes that easy for someone who knows what they are doing. Please help ASAP. I have to be done with this before tuesday afternoon. I am in central time zone(11:20pm right now).
