Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. That is why to prevent the spread of the disease, governments throughout the world ask their people to keep themselves quarantined at homes. During these quarantine period people spend their time productively if they learn new skills..... and... 2. Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. In our day to day meals, we should regularly have as vegetables add colour ... and...

Write a class studentInfo that represents a student record. It must have variables to store the student ID, student's name and student's CGPA. It also must have a function to print all the values. You will also need to overload a few operators. Create a list of objects of class studentInfo. Insert 5 student records . . 15234 Jon 2.6 13732 Tyrion 3.9 13569 Sandor 1.2 15467 Ramsey 2 3.1 16285 Arya 3.1 .

2. The table below summarizes information about the market for the principles of economics textbooks: Price (Tk.) Quantity Demanded Quantity Supplied 100 2000 100 200 1700 400 300 1400 700 400 1200 1200 500 800 1500 a) If the market price is 500 taka how many textbooks will be sold? b) If the market price of textbook is 100 taka, will there a shortage or surplus, and by how much? c) How will sellers respond to this (part b)? d) What is the equilibrium price and quantity of textbooks? e) If more efficient printing machines are invented, show graphically how this affects the equilibrium price and quantity of textbooks sold.

Q.3: (7 + 5 CLO2 [63] a) The diagrams shown below are the result of executing an algorithm which has one parameter, N, which must be a non-negative integer, and alphabet boxes on a 10x10 grid. For values of N from 0 to 5, the algorithm produces the following patterns: B RG B RG RB RG RB RG NEO N=1 N=2 G RB RIG RB RG B RIG RB RG RB RG G RB RG RB RG RB RG N=3 N=4 N25 Note: you can use the function CharXY(int x, int y, char C) to display the required char in the required box b) Write an algorithm convert an input non-negative integer to a string of octal numbers. Note: make sure that the string are printed in the correct order. Q.4: (7+5+5+5 Marks, CLO3 (C3])

A blocked rotor test was performed on the motor of the following were obtained line to line voltage - 26 V: total input current 32 A: Input wattmeter readings, W - 1430 W. W = -860 W. Calculate the equivalent resistance and reactance of the motor referred to stator.
