Which term describes the process where a computer’s memory is accessed in a sequential order?
सही उत्तर: ख) Random Access Memory (RAM)
RAM utilizes random access, meaning any location can be accessed directly and quickly. DMA allows external devices to access RAM without the CPU's intervention; serial communication deals with data transmission; cache memory is a smaller, faster memory used for frequently accessed data.

What does a ‘loop’ primarily accomplish in programming?
सही उत्तर: ख) To execute a block of code repeatedly
A loop is fundamental to repetitive execution of code blocks. The other options relate to different programming concepts like data types, data storage, and input handling.

In MS Excel, what does the function ‘SUM’ primarily calculate?
सही उत्तर: ग) The sum of a range of cells
The SUM function is specifically designed to add up all the numerical values within a specified range of cells. The other options represent different Excel functions – AVERAGE, MAX, and COUNT respectively.

Which of the following statements regarding the principle of superposition in acoustics is correct? (a) The total sound pressure at any point is the sum of the pressures from individual sources. (b) The sound waves interfere constructively only if they are perfectly in phase. (c) The loudness of a sound decreases proportionally to the distance from the source. (d) The superposition principle applies equally to all types of waves, regardless of their properties.
सही उत्तर: क) (a) The total sound pressure at any point is the sum of the pressures from individual sources.
The principle of superposition states that the resultant wave is the sum of all individual waves present at a point. Therefore, (a) correctly describes this principle. Option (b) refers to constructive interference, and (c) relates to sound intensity decreasing with distance.

A particle moves along a straight line with constant acceleration. The distance traveled in time ‘t’ is given by: (a) Distance = v₀t + (1/2)at² (b) Distance = vt + (1/2)at² (c) Distance = at² (d) Distance = (1/2)at²
सही उत्तर: घ) (d) Distance = (1/2)at²
The equation for distance traveled with constant acceleration is Distance = (1/2)at², where a is the acceleration and t is time. Option (c) correctly represents this formula.

The force required to move an object across a surface with a constant speed is: (a) Zero (b) Equal to the weight of the object (c) Equal to the normal reaction between the object and the surface (d) Equal to the gravitational force acting on the object
सही उत्तर: ग) (c) Equal to the normal reaction between the object and the surface
According to Newton’s First Law, when an object moves with constant velocity, the net force acting upon it is zero. Therefore, the correct answer is (c), which represents the balance of forces.

A uniform rod of length L and mass M is suspended by a thread from one end. If the thread is pulled horizontally through the center of the rod, the length of the thread will decrease by: (a) L/2 (b) L (c) 2L (d) 3L
सही उत्तर: क) (a) L/2
When the thread is pulled horizontally through the center of the rod, it creates a torque that rotates the rod. The change in thread length is directly proportional to the distance from the suspension point – in this case L/2.

The phenomenon of refraction of light occurs when light passes from one medium to another due to change in: (a) Speed of the light (b) Direction of the light (c) Wavelength of the light (d) Intensity of the light
सही उत्तर: क) (a) Speed of the light
Refraction is caused by the change in the speed of light as it enters a different medium. The most tempting answer, (b), describes reflection, not refraction. Option (c) relates to wavelength but doesn’t explain the overall phenomenon.

A light bulb emits light when an electric current passes through it. This phenomenon is known as: (a) Thermal Conduction (b) Incandescence (c) Electroluminescence (d) Photoluminescence
सही उत्तर: ख) Incandescence
Incandescence is the emission of light due to heat generated by a heated object. The electric current in the bulb heats up the filament, causing it to glow and emit light. Electroluminescence is the emission of light from electrical action, while thermal conduction and photoluminescence describe different processes.

यदि y = cos³(x), तब dy/dx पत्ता लगाउनुहोस्।
सही उत्तर: क) -3cos²(x)sin(x)
श्रृङ्खला नियमानुसार, dy/dx = 3cos³(x) * (-sin(x)) = -3cos³(x)sin(x)। अन्य विकल्पहरू गलत हुन् किनकि उ तिले श्रृङ्खला नियमावलीको प्रयोगलाई सही तरिकाले लागू गरेका छैनन।
