Answers

1. (c)

2. (b)

3. (a)

4. (d) There is a total of 32 keywords in C. See following table.


5. (a) 1 byte or 8 bits

6. (b) The time required to find an object stored in memory can be significantly reduced if the stored data can be identified by the content of the data for its own use rather than by access. A memory unit accessed by a material is known as an associative memory or a content addressable memory (CAM). This type of memory is accessed simultaneously and in parallel based on the data content rather than the specific address or location. if a word is written in associative memory, no address is given. Memory is capable of finding empty unused space to store the word, or part of the word specified. memory detects all words that match the specified content and marks them for reading.

7. (c)

8. (d)

9. (b) 
Step 1: Is this a positive or a negative number?
In a signed binary two's complement, the first bit (the leftmost) indicates the sign,
1 = negative, 0 = positive.
1101 0010 is the binary representation of a negative integer, on 8 bits.

Step 2. Get the binary representation in one's complement:
Run this step only if the number is negative
Subtract 1 from the binary initial number:
1101 0010 - 1 = 1101 0001

Step 3: 3. Get the binary representation of the positive (unsigned) number:
Run this step only if the number is negative
Flip all the bits in the signed binary one's complement representation (reverse the digits i.e. 0 to 1 and 1 to 0) - replace the bits set on 1 with 0s and the bits on 0 with 1s:
1101 0001 = 0010 1110

Step 4. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:
0010 11102 
= (0 × 27 + 0 × 26 + 1 × 25 + 0 × 24 + 1 × 23 + 1 × 22 + 1 × 21 + 0 × 20)10 
= 4610
If needed, adjust the sign of the integer number by the first digit (leftmost) of the signed binary:
1101 0010₂ = - 46₁₀

10. (a) BIOS, in full Basic Input/Output System, is the computer program that is typically stored in EPROM and used by the CPU to perform start-up procedures when the computer is turned on. Its two major procedures are determining what peripheral devices (keyboard, mouse, disk drives, printers, video cards, etc.) are available and loading the operating system (OS) into main memory.

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.

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...
