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.
