Consider the following project.

1. Draw the AON Network Diagram
2. Compute the expected activity time
3. Using the expected activity times, compute the early start, early finish, late start, late finish, and total float for each activity.
4. Compute the probability of completing the critical path in 69 days.

Calculate the instantaneous position of the Sun in the sky at “Solar Noon” on August 1st for Berlin,
Tegel Airport (52.55º N, 13.28º E) in terms of Solar Altitude Angle and Solar Azimuth Angle.
b) Calculate the Solar Angle of Incidence on the surface of a “South” oriented PV module at the same
time instant at the same geographical location.
(Hint: Calculate the Sun`s position in the sky for a normal year)

1. Suppose that 1 US$ = 1.5 South African Rand. Also, suppose that the representative good, peanut butter, is $3 per jar in the US and 4 Rand per jar in SA. How will this situation affect the exchange market for U.S. dollars? Explain/show the effect(s) of these prices. Include the initial effect(s), the market adjustment(s), and the final result(s) on equilibrium. (9 pts.)

would you expect the United States to trade more with a) Mexico or Luxembourg, b) Japan or South Africa, c) China or Germany. Why? (Hint: Do not look up actual values here. Use a model we have studied). What if you found that based on the criteria you used, we trade with Ireland and Australia more than we expected. Why might that be?

In the last 15 years, Bangladesh has seen rapid industrial development and export growth, mostly in the garment industry. According to the readings and class notes, (a) working conditions, industrial accidents and wages are among the worst in Asia. Discuss. (b) Nevertheless, social conditions mostly exceed those in the rest of South Asia and have improved dramatically over the years, in large part because of NGOs. Discuss.

A 2100 kg truck is driving south through an intersection at 40 mph when it crashes into a 1200 kg car that was driving east through the intersection at 55 mph. The two vehicle stick together in a sad, scary, twisted mess. What is the velocity (both magnitude and direction) of the wreckage immediately after the collision, before the vehicles have had any time to slow due to friction?

To get to a concert in time, a harpsichordist has to drive 122 miles in 1.93 hours. (a) If he drove at an average speed of 52.0 mi/h in a due west direction for the first 1.22 h, what must be his average speed if he is heading 30.0° south of west for the remaining 42.6 min?(b) What is his average velocity for the entire trip?(give magnitude and direction)

Eskom is a power company conglomerate in the South Africa and operates several power plants throughout the region, a few of them nuclear power plants. Needless to say, the public is concerned with emissions in the air surrounding these plants. Examine what public opinion means and critically discuss the questions the public relations specialists at Eskom must understand about public opinion before deciding on an appropriate campaign.
