2. Use the money market diagram (liquidity preference framework) to analyze the effects of the following on the interest rate. (a) Decrease in the money supply (b) Increase in real output (c) Decrease in the price level
25. Give an example of a nanomaterial that is >100 years old. 26. An ideal metal would be expected to expel electromagnetic fields (i.e. reflect EM waves). Why do some metals and metallic oxides have colour (even look black)? 27. How can a metal be modified to become black?28. What can be done to mitigate the effect of tunnelling across gate oxides in integrated microelectronics?
A Cypress Video Store (CVS) runs a series of fairly standard video stores. Before a video can be put on the shelf, it must be catalogued and entered into the video database. To rent a video, every customer must have a valid CVS customer card. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that he or she does not have any overdue videos. If so, the overdue videos must be returned and the customer must pay a fine before renting more videos. Likewise, if the customer has returned overdue videos, but has not paid the fine, the fine must be paid before new videos can be rented. Every morning, the store manager prints a report that lists the overdue videos.
Based on the readings and your research, select one program design technique of your choice (structure chart, Use Cases, ERD, and DFD). Using MS Visio software, create a diagram for the CVS system to process video renting activities. Copy and paste your diagrams into a Word document. Explain in a short paragraph why you chose this technique? Make sure you cite your sources with APA guidelines.

(i) Show that the skin depth for Cu at 5×1015 Hz (middle of the visible light band) is
approximately 1 nm, compared to 10 mm at 50 Hz (AC mains frequency). (4 marks)
(ii) Show that for Cu the limit s e? ? corresponds to 18 f 010 Hz , meaning that this
approximation applies at frequencies up to at least the ultraviolet. (3 marks)
