SI stands for “Système International d’Unités,” which is French for the “International System of Units.” It is the modern form of the metric system and the most widely used system of measurement for science, engineering, and commerce worldwide. The SI system is maintained by the International Bureau of Weights and Measures (BIPM) and consists of seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity).
67. Mass is a _____
A. Scalar quantity
B. Vector quantity
C. Free quantity
D. Dependent quantity
Solutions
Mass is a scalar quantity because it only has magnitude and no direction. Scalars are quantities that are fully described by a numerical value alone, whereas vectors have both magnitude and direction. Examples of scalar quantities include mass, temperature, and time. In contrast, examples of vector quantities include force, velocity, and displacement.
68. A bullet fired from a gun can pierce a target due to its ___________
A. Mechanical energy
B. Heat energy
C. Kinetic energy

Solutions
When a bullet is fired from a gun, it possesses a high velocity and, consequently, a significant amount of kinetic energy. Kinetic energy is the energy an object possesses due to its motion, and it is given by the formula:
where m is the mass of the bullet and v is its velocity. The high kinetic energy of the bullet is what allows it to pierce the target upon impact.

71. The logical instruction that affect the carry flag during its execution is_______
A. ORL A
B. XRL A
C. RL A
D. ANL A
Solutions
The logical instruction that affect the carry flag during its execution is RL A. The RL (Rotate Left) instruction rotates the contents of the accumulator (A) left by one bit position. The bit that is rotated out of the most significant bit position (bit 7) is transferred to the carry flag (CY), and the carry flag is shifted into the least significant bit position (bit 0). This means that the carry flag is updated based on the value of the most significant bit before the rotation.

75. A bistable multi-vibrator that functions as a voltage comparator with hysteresis is called
A. T flip-flop
B. D flip-flop
C. J-K flip-flop
D. Schmitt trigger
Solutions
A Schmitt trigger is a bistable circuit that converts a non-sinusoidal input waveform to a square wave output. It has two threshold voltage levels, and the output of the Schmitt trigger changes state when the input voltage crosses either of these thresholds. The Schmitt trigger is commonly used as a voltage comparator with hysteresis, which means that the output voltage depends not only on the input voltage level but also on the previous state of the circuit. This feature makes it useful for applications such as noise filtering and signal conditioning.

80. What is the group of 1s in 4 cells of a K – map called?
A. Pair
B. Quad
C. Octet
D. None of the above
Solutions
In a Karnaugh map (K-map), a group of 1s in 4 adjacent cells is commonly referred to as a “quad.” This term is used to describe a group of four 1s that form a rectangular shape in the K-map. The quad represents a set of minterms that can be combined to simplify a Boolean expression. So, the correct answer is Quad.
81. Which of these pins will allow to activate and deactivate a multiplexer?
A. Logic pin
B. Selection pin
C. Enable pin
D. Preset pin
Solutions
The pin that allows you to activate and deactivate a multiplexer is typically referred to as the “Enable pin”. This pin is used to enable or disable the operation of the multiplexer. When the enable pin is set to a specific logic level (usually high or low, depending on the specific multiplexer design), the multiplexer either allows the data to pass through or holds its output in a specific state.

A. It has to do a lot of power distribution
B. The majority of charge carriers has to supply to the base
C. It is the first region of the transistor
D. It is necessary to have low resistance.
Solutions
Transistor’s emitter’s a large amount of doped, because the majority of charge carriers has to supply to the base.
The emitter of a transistor is heavily doped to ensure that it has a high concentration of charge carriers (either electrons for an NPN transistor or holes for a PNP transistor). This is important because the primary function of the emitter region is to supply a large number of charge carriers to the base region. In an NPN transistor, for example, the emitter emits electrons into the base region to enable the transistor to amplify the current. By having a high concentration of charge carriers in the emitter, it can easily supply the base region with the required carriers for proper transistor operation.
