Computing & Informatics - true/false type questions from AMIE exams

True/false type questions.
  1. Pentium is a 32-bit machine because it has got a 32-bit Address Bus.
  2. Unix is a multiuser operating system. 
  3. C is a procedural programming language.
  4. A C++ compiler actually translates a C++ source code into the equivalent machine code of the target CPU.
  5. The operating system acts as a resource manager for any computer system.
  6. When one needs to connect all the computers in one building, then it is preferable to use a LAN.
  7. TCP/IP is actually two protocols rolled into one.
  8. If is a valid C++ identifier.
  9. A-23 is a valid C++ constant.
  10. Flash memory is a writable non-volatile memory.
Answers
  1. False. Pentium is a 32-bit machine that indicates the number of data lines and internal register size is 32 bits. It can do operations (addition, subtraction etc.) on 32-bit operands.
  2. True. Through the multiprogramming feature, multiple users can work on a Unix machine at the same time.
  3. True. C uses procedures (functions and blocks) to implement code. Each procedure indicates steps that are to be followed to solve a given problem.
  4. True. Like any compiler, the C++ compiler translates C++ source code into the machine code of the target CPU.
  5. True. The function of the operating system is to manage the resources (memory, processors, I/O systems, information etc.)
  6. True. Local Area Network (LAN) is specifically designed to handle data transfer between computers that are geographically near (within usually a 1 km radius). They transfer data through a physical medium at high data rates and low error rates. Thus it is most suitable for connecting computers in a building. 
  7. True. It contains two protocols one is the transmission protocol that deals with the transportation of packets from source to destination (TCP). Another protocol is IP (Internet protocol) which is specifically for transporting data through the Internet. 
  8. True. “If” is a valid identifier but “if” is not a valid identifier, “if “ is a reserved word.
  9. False. A-23 is not a valid constant. It contains a variable “A”.
  10. True. Flash memories use EEPROM (electronically erasable programmable read-only memory). Data can be written and erased as many times as we wish. EPROM (Erasable Programmable Read-Only Memory) are non-volatile. Data is not lost when power is turned off.

Mechanics of Fluids (Solved Numerical Problems)

Numerical The surface Tension of water in contact with air at 20°C is 0.0725 N/m. The pressure inside a droplet of water is to be 0.02 N/cm² greater than the outside pressure. Calculate the diameter of the droplet of water. (7 marks) (AMIE Summer 2023) Solution Surface tension, σ = 0.0725 N/m Pressure intensity, P = 0.02 N/m 2 P = 4σ/d Hence, the Diameter of the dropd = 4 x 0.0725/200 = 1.45 mm Numerical Find the surface tension in a soap bubble of 40 mm diameter when the inside pressure is 2.5 N/m² above atmospheric pressure. (7 marks) (AMIE Summer 2023) Answer: 0.0125 N/m Numerical The pressure outside the droplet of water of diameter 0.04 mm is 10.32 N/cm² (atmospheric pressure). Calculate the pressure within the droplet if surface tension is given as 0.0725 N/m of water. (AMIE Summer 2023, 7 marks) Answer: 0.725 N/cm 2   Numerical An open lank contains water up to a depth of 2 m and above it an oil of specific gravity 0.9 for a depth of 1 m. Find the pressure intensity (i) at t...

Energy Systems (Solved Numerical Problems)

Wind at 1 standard atmospheric pressure and \({15^0}C\) has velocity of 15 m/s, calculate (i) the total power density in the wind stream (ii) the maximum obtainable power density (iii) a reasonably obtainable power density (iv) total power (v) torque and axial thrust Given: turbine diameter = 120 m, and turbine operating speed = 40 rpm at maximum efficiency. Propeller type wind turbine is considered. (AMIE Winter 2023) Solution For air, the value of gas constant is R = 0.287 kJ/kg.K 1 atm = 1.01325 x 105 Pa Air density \(\rho  = \frac{P}{{RT}} = \frac{{1.01325x{{10}^5}}}{{287}}(288) = 1.226\,kg/{m^3}\) Total Power \({P_{total}} = \rho A{V_1}^3/2\) Power density \(\begin{array}{l}\frac{{{P_{total}}}}{A} = \frac{1}{2}\rho {V_1}^3\\ = \frac{1}{2}(1.226){(15)^3}\\ = 2068.87{\mkern 1mu} W/{m^2}\end{array}\) Maximum power density \(\begin{array}{l}\frac{{{P_{\max }}}}{A} = \frac{8}{{27}}\rho A{V^3}_1\\ = \frac{8}{{27}}(1.226){(15)^3}\\ = 1226{\mkern 1mu} W/{m^2}\end{array}\) Assuming eff...

Design of Electrical Systems (Solved Numerical Problems)

Important note There is something wrong with this question paper. It seems that instead of "Design of Electrical Systems" the IEI has given problems from "Electrical Machines". You should raise a complaint to director_eea@ieindia.org in this regard. Numerical A 120 V DC shunt motor draws a current of 200A. The armature resistance is 0.02 ohms and the shunt field resistance is 30 ohms. Find back emf. If the lap wound armature has 90 slots with 4 conductors per slots, at what speed will the motor run when flux per pole is 0.04 Wb?​ (AMIE Summer 2023, 8 marks) Solution The back EMF (E b ) of a DC motor can be calculated using the formula: E b = V - I a R a   Given: V = 120 V I a = 200 A R a = 0.02 ohms Substituting the values into the formula: E b = 120 − 200 × 0.02 = 120 − 4​ = 116 V Now, let's calculate the speed (N) at which the motor will run using the given flux per pole (φ p ). The formula to calculate the speed of a DC motor is: N = 60×E b /(P×φ p ) Wh...
