A medical cyclotron used in the production of medical
isotopes
accelerates protons to 6.5 MeV. The magnetic field in the
cyclotron is 1.2 T.
a. What is the diameter of the largest orbit, just before the
protons
exit the cyclotron?
b. A proton exits the cyclotron 1.0 ms after starting its
spiral
trajectory in the center of the cyclotron. How many orbits
does the proton complete during this 1.0 ms?

Draw a graph showing the impact of increasing land available in the West from federal land sales. This will result in a reallocation of labor from the East to the West (modelling westward migration). A complete answer should show the marginal product of labor, the level of rents in east and west, and the amount of labor in East and West (both before and after) clearly shown.

A firm uses INR 50 million of debt, INR 15 million of short-term debt, and INR 90 million of common equity to finance its assets. If the before-tax cost of debt is 10%, after-tax cost of short-term debt is 8%, and the cost of common equity is 16%, calculate the weighted average cost of capital for the firm assuming a tax rate of 20%.

Draw a graph that shows the demand for a single stadium that holds games for the St. Louis Cardinals. Assume that the supply curve for seating is horizontal and then vertical. Further assume that you are graphing the attendance of one particular game on the horizontal axis. Graphically show and verbally explain why the price and quantity might be different after Dexter Fowler (star player) has joined the team than it was before.

Two polls were taken for the approval of Donald Trump. The first was a random selection taken before the events at Charlottesville of 1000 people and 440 indicated support for Trump. The second was taken immediately after Charlottesville where 1000 people were randomly selected and 380 expressed support for Trump. Test against a 95% probability Zα/2 = 1.96 that the difference was due to random variation.

Question 2 – Government Intervention as Anti-Trust Laws
Sometimes governments intervene with the markets; the reason for the intervention might be a concern about allocative efficiency, or production inefficiency or some “fairness” issue.
Your task here is to explain the motivation for government instituting laws against forming cartels (price fixing). Analyze the situation before and after government intervention, and then conclude by referring to the possible reason for intervention.

(c7p44) An Escort and a Camaro traveling at right angles collide and stick together. The Escort has a mass of 1100 kg and a speed of 40 km/h in the positive x direction before the collision. The Camaro has a mass of 1700 kg and was traveling in the positive y direction. After the collision, the two move off at an angle of 74 o to the x axis. What was the speed of the Camaro?(in km/h)
