Problem 2) What is the frequency of an AC waveform having a period of 0.2 μs? Problem 4) The peak value of a sine wave is 169.73 Volts (Vpk). What is the RMS value (VRMS)? Problem 6) What is the peak-to-peak voltage (Vp-p) across a 10-kΩ resistor that dissipates 50 mW? Problem 8) The AC effective voltage across a given resistor doubles. What happens to the power dissipated by the resistor? Problem 10) The RMS value of a given AC voltage is 75 Volts (75 VRMS). What is the peak value (Vpk)? What is the peak-to-peak value (Vp-p)? This is a two-part question. You need two answers. Problem 12) One alternation of a signal takes 500 μs. What is its frequency (f)? What is the time of two periods? (Use a calculator to find answers). This is a two-part question. You need two answers. Problem 14) What is the wavelength (λ) of a radio signal with a frequency of 1 MHz?

Q1 Design a class named Square to represent a Square. The class contains: (5 marks) 1. private double data fields named side that specify the one side of the Square. The default values is 1. 2. A no-arg (default) constructor that creates a default Square. 3. A constructor that creates a Square with the specified side. 4. Getter and sitter ( square side cannot be negative) 5. A method named getArea() that returns the area of this Square. (side * side) 6. A method named getPerimeter() that returns the perimeter. (4 * side) A. Draw the UML diagram for the class and then implement the class. B. Write a test program that creates two square objects- one with default value and the other with side = 4; C. Display the side, area, and perimeter of each square in this order.

(10 points): What is the difference between a goal-based agent and a utility-based agent? (20 points): Develop a PEAS description of the task environment for the following: a. Robot soccer player b. Internet book-shopping agent (40 points): For each of the following assertions, say whether it is true or false and support our answer with examples or counterexamples where appropriate. a. An agent that senses only partial information about the state cannot be perfectly rational. b. There exists a task environment in which every agent is rational. c. The input to an agent program is the same as the input to the agent function. d. Every agent function is implementable by some program/machine combination. (5 points): An Agent is made up of its architecture and its program a. Ture b. False 4. (5 points): Which one is correct? An environment is Deterministic when the next state of the environment is: a). partially determined by the current state. b). partially determined by the current state and the action executed by the agent. c). totally determined by the current state and the action executed by the agent.
