4. Consider an electric dipole of charge q that is centered on the origin where the two charges lie on the y axis and are separated by a distance d.

a. Determine the electric field at an arbitrary position near the dipole. In other words, determine E~ (x, 0).

b. An electron is released from rest at the point (L, 0). Determine the acceleration of the electron at the moment it is released.

c. A proton is released from rest at the point (L, 0). Determine the acceleration of the proton at the moment it is released.

You want to buy a boat that costs today $40,000. Your plan is to save monthly amount so that you will have enough money to purchase the boat three years from now. The rate of inflation of boats is expected to be 3% per year for the near future, and your bank pays an interest rate of 3% per year compounded monthly. How much money you should save every month to buy the boat three years from now?

The tube length in a certain compound microscope is 25 cm. The focal length of the objective lens is 2.1 cm. The clearest image is formed when an object of height 1 mm is placed at a distance of 2.3 cm from the objective lens. Determine: (i) The position of the intermediate image, (ii) the focal length of the eye piece, that will place the final image at the near-point, (iii) the total magnification of the microscope and the height of the image, (iv) sketch to scale a ray diagram that verify your findings.

There are two carotid arteries that feed blood to the brain, one on each side of the neck and head. One patient's carotid arteries are each 11.2 cm long and have an inside diameter of 5.2 mm . Near the middle of the left artery, however, is a 2.0-cm-long stenosis, a section of the artery with a smaller diameter of 3.4 mm .For the same blood flow rate, what is the ratio of the pressure drop along the patient's left carotid artery to the drop along his right artery?

You have been asked to estimate the value of a home for sale. The subject property has three bedrooms, one bathroom, and is in good condition. A highly comparable property just sold near the subject recently. You will use this recent sale as the comp to estimate value of of the subject property. The comp sold for $134,000. It has three bedrooms, two bathrooms, and is in good condition. Assume bedrooms are worth $5,000 and bathrooms are worth $3,000. What is the indicated value of the subject property based on the comparable sale?

You have been asked to estimate the value of a home for sale. The subject property has three bedrooms, two bathrooms, and is in good condition. A highly comparable property just sold near the subject recently.

The comp sold for $127,900. It has three bedrooms, one bathroom, and is in good condition.

Assume bedrooms are worth $4,500 and bathrooms are worth $2,700.

What is the indicated value of the subject based on the comparable sale? (please show all work below for full credit:)

Respond to each short answer question using two to three well-constructed paragraphs (150 – 250 words) containing specific details and examples that support your understanding of the concepts.

1. Assume that gasoline is a normal good. What would happen to the market for gasoline in each of the following cases:

1. The price of automobiles rises
2. Consumers believe that gasoline prices will rise in the near future.
3. U.S. producers increase the production of gasoline
4. Oil field workers win a pay increase

A rocket has an initial mass of 28500 kg, of which 20% is the payload (i.e., the mass of the rocket minus the fuel). It burns fuel at a rate of 195 kg/s and exhausts its gas at a relative speed of 1.5 km/s.

(a) Find the thrust of the rocket.
kN
(b) Find the time until burnout.
s
(c) Find its final speed assuming it moves upward near the surface of the earth where the gravitational field g is constant.
km/s

1. (In one paragraph) Explain how the Bureau of Labor Statistics uses two parts of a fraction to compute the unemployment rate each month. Then describe how the concept of "Natural Unemployment" within a market economy means that the unemployment rate is always above zero (0.0%). And make sure to discuss whether (or not) you think that the United States economy is currently near the "Full Employment" level.

2. Summarize how Frictional Unemployment and Structural Unemployment are forms of Natural Unemployment.
