Activity 2: A common emitter amplifier is shown below. 15 V 15 V $13 k\Omega$ $350 k\Omega$ $300 k\Omega$ $10 k\Omega$ Assuming that $\beta = 100$ and $V_{BE} = 0.7 V$, and ignoring $r_o$, solve the following: (2-a) Determine the Q point. (2-b) Draw the small-signal equivalent circuit model of the amplifier. (2-c) Find the input and output resistances, total voltage gain, and current gain. (2-d) Use Multisim to verify all of your results. Compare and comment.

Now suppose that there are credit market imperfections in the market for consumer credit, for example, due to asymmetric information in the credit market. Determine the equilibrium effects on consumption, investment, the real interest rate, aggregate output, employment, and the real wage. What is the multiplier and how does it differ from the government expenditure multiplier? Part 5 The presence of credit market imperfections in the market for consumer credit would result in the output demand curve â–¼ becoming steeper, shifting to the left, shifting to the right, flattening out, due to some consumers experiencing â–¼ an increase no change a decrease in lifetime wealth because of credit market constraints. These consumers would â–¼ not change increase decrease their labour supply, and there would be â–¼ a shift to the left in the no change in the a shift to the right in the labour supply curve and output supply curve. Overall, the level of aggregate output â–¼ should increase, should decrease, should remain constant, and the real interest rate â–¼ will increase. will remain the same. will decrease. Consumption â–¼ decreases, increases, remains the same, investment â–¼ decreases, increases, remains the same, and employment â–¼ remains the same. increases. decreases. There is a â–¼ positive negative multiplier, and the extent of the effect on output is dependent on how many consumers are credit-constrained.

Why is it correct to say that bison were hunted nearly to extinction in the North American Great Plains? From a peak population of about 1 million bison historically, only about 500 remained by the end of the 1800s. From a high of about 30 million bison historically, only about 500 remained by the end of the 1800s. Because hunters in the 1900s killed all bison that were free roaming, leaving only those in zoos and wild animal sanctuaries surviving. Because all but about 10,000 bison were killed before the end of the 1800s. Because 10 million bison were killed in the 1900s, leaving only about 100,000 remaining in this region.

A sociologist believes that the median age at which women marry in Burrusville is less than the median age of 26.9 years for the entire United States. Based on a random sample of 20 marriage certificates from Burrus County, the following statistics were produced via StatCrunch. Hypothesis test results: Variable: median of Variable n: 20 n for test: 20 Sample Median: 25 Below: 12 Equal: 0 Above: 8 P-value: 0.2517 At alpha = 0.05, is there evidence to support the sociologist's claim? Be sure to state a null and alternate hypothesis, and what evidence you are using from the StatCrunch output to support your conclusion. If you need it, the critical value is 5.

Objective: Create classes that represent three dimensional shapes and can be sorted based on their volume. Details: Define the following classes with the methods specified. Note that get/set functions are NOT required for this assignment. You can assign all values in the constructor. 1. The Shape3D Class • This is an abstract class that implements the Comparable interface • Contains an abstract method called Volume() that returns a double • There are no input parameters to this method • Defines a compareTo method that compares itself to another Shape3D classes • HINT: Remember to implement Comparable with your class name • implements Comparable<Shape3D> • HINT: When defining compareTo use Shape3D other as the input parameter • Calls the abstract Volume() method and compares the result • if this.Volume() > other.Volume() return 1 • else if this.Volume() < other.Volume() return -1 • else return 0 2. The Cuboid class • This extends the Shape3D class • Contains the following attributes • width - integer • depth - integer • height - integer • Contains a constructor class where width, depth and height are set via input parameters • Overrides the Volume() method • return width * depth * height 3. The Cylinder Class • This extends the Shape3D class • Contains the following attributes • radius - integer • height - integer • Contains a constructor class where radius and height are set via input parameters • Overrides the Volume() method • return Math.PI * radius * radius * height 4. Test Class • The test class contains your main method. • In your main method create a Cuboid and a Cylinder • You can set the dimensions to whatever you want • Use the compareTo method to output which has the greater volume, the cuboid or the cylinder or if they are equal Submission: Submit the four .Java files you created for this project.
