• Bud Light ran a SuperBowl advertisement stating that it does not use corn syrup – in direct contrast to its competitors. The Bud Light marketing department wants to know the impact of the ad (IV) on consumer brand perceptions (DV). They therefore compare consumer perceptions of the brand collected before the SuperBowl with consumer perceptions of the brand collected after the ad was shown in the SuperBowl.
  • What form of study design is this?
  • Will the researcher be able to make claims about causality with this study?

1. Draw a well-presented and well-labelled supply and demand diagram to show the welfare effects of rent control.
2. Using your diagram from part (a) construct a well-presented table that shows the consumer surplus, producer surplus, total surplus and deadweight loss both before and after the rent control has been put in place.
3. According to your diagram has consumer surplus increased or decreased? Briefly explain consumer surplus has decreased or increased.

Environmental Engineering

Water Treatment.

Question 1:

Aeration is particularly utilized to supply oxygen in water treatment.

a) How much oxygen is required for drinking water?

b) How do the impurities (pollutants or other ions) in water affect aeration efficiency?

Question 2:  

A) How do you classify the settling types? Explain briefly.

B) Explain use of sedimentation units in water treatment (i.e. before or after which processes is sedimentation required).

An oscillating LC circuit is set up with an inductor with L = 60 mH and a capacitor with C = 4.0 µF with a maximum voltage of 3.0 V. Initially, at t = 0, the capacitor is fully charged.

(a) What is the maximum value of the current through the circuit?

(b) How long after t = 0 will it take before the current in the circuit is at a maximum for the first time?

(c) What is the maximum rate of change of the current in the circuit?

(d) What is the total energy stored in the circuit?

A firm has 2,000,000 shares of stock outstanding, total debt of $3,000,000 at an annual interest rate

of 8% and annual depreciation expense of $300,000, and is considering borrowing an additional

$6,000,000 at 8% and buying back one-half of those shares. Assuming EBIT of $1.2 million, what is this

company’s cash coverage ratio (a) before and (b) after the proposed restructuring? What can you

conclude about the impact of financial leverage on a firm’s cash coverage ratio?

16. On a frictionless horizontal air table, puck A (with mass 0.255 kg ) is moving toward puck B (with mass 0.375 kg ), which is initially at rest. After the collision, puck A has velocity 0.125 m/s to the left, and puck B has velocity 0.649 m/s to the right.

Part A: What was the speed vAi of puck A before the collision?

Part B: Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

: After reading the assigned text, sit at the steps of your building/house for 20 minutes and observe what you see. Practice writing ethnographic field notes in your field notebook. What have you observed? Did you notice anything you have never noticed before? Response: Write a 250 - 400 word response in the discussion board. Summarize key points in the reading. Share your experiences of sitting on your steps.

// This program uses a bubble sort to arrange an array of integers in

// ascending order (smallest to largest). It then display the array

// before the sorting and after the sorting. Modify the program so it orders

// integers in descending order (largest to smallest). Then add some code

// to display the array at each step of the algorithm. You don't have to

// modify anything in the main() function. All modification are inside

// the bubbleSortArray() function.

// EXAMPLE:

// The values before the bubble sort is performed are: 9 2 0 11 5

// The values are: 9 2 0 11 5

// The values are: 9 2 0 11 5

// The values are: 9 2 11 0 5

// The values are: 9 2 11 5 0

// The values are: 9 2 11 5 0

// The values are: 9 11 2 5 0

// The values are: 9 11 5 2 0

// The values are: 11 9 5 2 0

// The values are: 11 9 5 2 0

// The values are: 11 9 5 2 0

// The values after the bubble sort is performed are: 11 9 5 2 0
