ANS:C - Pallete

Explanation: All except Pallete are parts of a gun.

ANS:D - closed

The flow of electrons is called current. The protons are inside the nucleus so they do not flow. They are immobile. The positive charge that is said to flow are holes which represent the empty spaces left by electrons. So they flow in the direction opposite to the flow of electrons. Since current also flows opposite to the flow of electrons, the direction of flow of protons is equal to the direction of flow of current.

ANS:A - 1 in 60

The gradient required for generating self-cleansing velocity in a sewer depends on various factors such as the diameter of the sewer, flow velocity, and the characteristics of the wastewater. Self-cleansing velocity refers to the minimum velocity required to prevent sediment deposition and maintain the sewer in a self-cleaning state. While the specific gradient required can vary depending on local standards, guidelines, and design considerations, a commonly used rule of thumb is that a gradient of approximately 1 in 100 (1%) is sufficient to achieve self-cleansing velocity for most sewer diameters. This means that for every 100 units of horizontal distance, there is a 1-unit change in elevation. Therefore, the closest option listed is:

• 1 in 100

ANS:C - VF

It is similar to triode.

The coefficient of performance (COP) of an absorption refrigeration system can be expressed as the ratio of refrigeration effect to the input energy (usually heat): COP=Refrigeration EffectInput EnergyCOP=Input EnergyRefrigeration Effect​ In an absorption refrigeration system, the input energy is typically heat, and the refrigeration effect is the amount of heat removed from the refrigerated space. The maximum COP for an absorption refrigeration system occurs when it operates in a reversible manner, known as the Carnot cycle. The Carnot cycle efficiency is given by: Carnot Efficiency=1−𝑇cold𝑇hotCarnot Efficiency=1−Thot​Tcold​​ Where:

• 𝑇coldTcold​ is the temperature of the refrigeration space (the lower temperature, often denoted as 𝑇𝑅TR​ in your notation).
• 𝑇hotThot​ is the temperature of the heat source (usually ambient temperature or 𝑇1T1​ in your notation).

ANS:C - Andhra Pradesh

The Surface Air Missile for Assured Retaliation (SAMAR) air defence missile system, successfully tested by the Indian Air Force at Air Force Station Suryalanka in Andhra Pradesh, is designed as a 'Surface to Air Missile,' marking a significant achievement in the IAF's strategic self-reliance efforts.

ANS:B - 2022-23

Rest of India won in the final of the Irani Cup for the year 2022-23.
