In a double slit experiment, if the separation between the slits increases, what happens to the distance between the interference fringes?

Which of the following colors produces the widest diffraction pattern

The experiment data in below table was to evaluate the effects of three variables on invoice errors for a company. Invoice errors had been a major contributor to lengthening the time that customers took to pay their invoices and increasing the accounts receivables for a major chemical company. It was conjectured that the errors might be due to the size of the customer (larger customers have more complex orders), the customer location (foreign orders are more complicated), and the type of product. A subset of the data is summarized in the following Table.

Table: Invoice Experiment Error

Customer Size: Small (-), Large (+)

Customer Location: Foreign (-), Domestic (+)

Product Type: Commodity (-), Specialty (=)

Objectives:

Design an electronic circuit to measure Celsius temperature.

Model the circuit with Multisim and validate its operating characteristics.

Design Requirements:

A need has arisen for an inexpensive electronic thermometer that will measure Celsius temperature over a specified range. The basis for the design is the property that the forward voltage of a diode decreases with increasing temperature and can be approximated by a straight-line linear equation. The feasibility as a transducer will be studied and the specifications are as follows:

                Input Temperature Range: 0^o C to 100^o C

                Realistic Circuit Output Voltage: 0 V to 10 V based on a calibration factor of 0.1 V/^o C

                Voltage Representing Temperature: 0 V to 100 V monitored by VCVS with a gain of 10

                Accuracy of ±0.5 ^oC at the two extreme input temperatures as measured at output of VCVS

                One 1N4148 diode to serve as the basis for the transducer

                No more than three 741 operational amplifiers (preferably two) and ± 15 V power supplies

                Resistor values as needed (Assume calibration to an accuracy of 3 significant digits.)

                One ideal voltage-controlled voltage source (VCVS) with a gain of 10 to monitor the output

Pg. 1       This page with data added as requested should be Page 1 of the report.

Pg. 2       The instructor will specify a bias current. Connect a DC Current Source across the diode.                Perform a Temperature Sweep from 0^o C to 100^o C and create a Multisim plot of diode voltage                 versus Celsius temperature for Page 2. Use the vertical intercept and the slope (dy/dx) to      determine the straight-line equation that describes the diode voltage as a function of the          temperature. Then solve for the temperature in terms of the diode voltage. List the results below.                                   

                Bias Current:      I.     II.     III.     IV.      V.                         

                Diode Voltage as a Function of Temperature:                                                          

                Temperature as a Function of Diode Voltage:

Pg. 3       Design a circuit to provide an output voltage in terms of input temperature. Add a Voltage Gain Block with a gain of 10 so that the ideal value of the output voltage is the input temperature. Show the Multisim schematic diagram of the circuit on Page 3.

Pg. 4      Use Temperature Sweep to obtain a Multisim plot of the output voltage versus input Celsius          temperature. Use cursors to measure the output at the two extreme input values.

Write a program in Java that reads a file containing data about the changing popularity of various baby names over time and displays the data about a particular name. Each line of the file stores a name followed by integers representing the name’s popularity in each decade: 1900, 1910, 1920, and so on. The rankings range from 1 (most popular) to 1000 (least popular), or 0 for a name that was less popular than the 1000^th name. A sample file called ‘population.txt’ has been given to you. Your program should prompt the user for a name and search the file for that name. If the name is found, the program should display the data about the name on the screen. If the name is not found, then display the message ‘Name not found in the file’

Your program should at-least have the following method:

checkName(): A method that takes the baby name as a parameter and returns true if the name exist and false otherwise.

Sample Output:

Name? Sam

Statistics on the name “Sam”

1900: 58

1910: 69

1920: 99
