Example 23

Example 23.9 derives the exact expression for the electric field at a point on the axis of a uniformly charged disk. Consider a disk, of radius R = 3.00 cm, having a uniformly distributed charge of + 5.20 μC.
(a) Using the result of Example 23.9, compute the electric field at a point on the axis and 3.00 mm from the center. What If? Compare this answer with the field computed from the near-field approximation E = 2/2) 0.
(b) Using the result of Example 23.9, compute the electric field at a point on the axis and
30.0 cm from the center of the disk. What If? Compare this with the electric field obtained by treating the disk as a +5.20-μC point charge at a distance of 30.0 cm.

Consider Simple Harmonic Oscillator

Consider a simple harmonic oscillator. Calculate the time averages of the kinetic and potential energies over one cycle, and show that these quantities are equal. Why is this a reasonable result? Next calculate the space averages of the kinetic and potential energies. Discuss the results.

Consider The Following Deadlock Detection Algorithm

Consider the following deadlock-detection algorithm. When transaction Ti, at site S1, requests a resource from Tj, at site S3, a request message with timestamp n is sent. The edge (Ti, Tj, n) is inserted in the local wait-for of S1. The edge (Ti, Tj, n) is inserted in the local wait-for graph of S3 only if Tj has received the request message and cannot immediately grant the requested resource. A request fromTi to Tj in the same site is handled in the usual manner; no timestamps are associated with the edge (Ti, Tj). A central coordinator invokes the detection algorithm by sending an initiating message to each site in the system. On receiving this message, a site sends its local wait-for graph to the coordinator. Note that such a graph contains all the local information that the site has about the state of the real graph. The wait-for graph reflects an instantaneous state of the site, but it is not synchronized with respect to any other site.

When the controller has received a reply from each site, it constructs a graph as follows:

• The graph contains a vertex for every transaction in the system.

• The graph has an edge (Ti, Tj) if and only if

 There is an edge (Ti, Tj) in one of the wait-for graphs.

 An edge (Ti, Tj, n) (for some n) appears in more than one wait-for graph.

Show that, if there is a cycle in the constructed graph, then the system is in a deadlock state, and that, if there is no cycle in the constructed graph, then the system was not in a deadlock state when the execution of the algorithm began.

A Consider Horizontal Interface

(a) Consider a horizontal interface between air above and glass of index 1.55 below. Draw a light ray incident from the air at angle of incidence 30.0°. Determine the angles of the reflected and refracted rays and show them on the diagram.
(b) What If? Suppose instead that the light ray is incident from the glass at angle of incidence 30.0°. Determine the angles of the reflected and refracted rays and show all three rays on a new diagram.
(c) For ray’s incident from the air onto the air–glass surface, determine and tabulate the angles of reflection and refraction for all the angles of incidence at 10.0° intervals from 0° to 90.0°.
(d) Do the same for light rays coming up to the interface through the glass.
