What kind of combustion occurs in a gun?
Correct Answer
C. Exothermic combustion
Explanation
Exothermic combustion occurs in a gun. Exothermic combustion is a type of combustion reaction that releases heat and light energy. In the case of a gun, when the gunpowder ignites, it undergoes exothermic combustion, resulting in the rapid release of gases and the generation of high pressure and temperature. This combustion process propels the bullet out of the gun barrel.
2.
Which of these is not a part of a firearm?
Correct Answer
C. Tunnel
Explanation
A tunnel is not a part of a firearm. A firearm typically consists of a cartridge, which contains the bullet, propellant, and primer, as well as a trigger mechanism to initiate the firing process. However, a tunnel does not serve any functional purpose in a firearm and is not necessary for its operation.
3.
In what type of firearms is gas pressurization mechanical?
Correct Answer
C. Air guns
Explanation
Gas pressurization in air guns is mechanical because these firearms use a piston or spring mechanism to compress air within a chamber. When the trigger is pulled, the compressed air is released, propelling the projectile forward. This mechanical process differs from shotguns and rifles, which typically use chemical reactions (such as combustion or explosion) to generate the necessary force for projectile propulsion. Toy guns, on the other hand, often rely on mechanisms like springs or air pumps to create the illusion of firing without using any actual propellant.
4.
In what century did man start producing guns?
Correct Answer
A. 10th century
Explanation
Guns were first produced in the 10th century. This marked the beginning of man's production of firearms, which revolutionized warfare and hunting techniques. The development of guns had a significant impact on the course of human history, leading to changes in military strategies and the balance of power between nations.
5.

6.
How can modern firearms be described?
Correct Answer
D. By their caliber
Explanation
Modern firearms can be described by their caliber, which refers to the internal diameter of the firearm's barrel. Caliber determines the size and type of ammunition that the firearm can use. It is an important characteristic as it affects the power, range, and accuracy of the firearm. Different calibers are used for different purposes, such as self-defense, hunting, or target shooting. By describing firearms by their caliber, it provides a standardized way to understand and compare different types of firearms.
7.
Which of these is not a type of firearm?
Correct Answer
C. Lift hacker
Explanation
The term "lift hacker" does not exist in the context of firearms. It is not a recognized type or category of firearm. Bolt loader, muzzleloader, and pump action are all types of firearms that have specific mechanisms for loading and firing ammunition.
8.
What skill do shooters need to hit a target?
Correct Answer
D. Eye-hand coordination
Explanation
Shooters need eye-hand coordination in order to hit a target. Eye-hand coordination refers to the ability to synchronize visual information with motor movements. In shooting, this skill is crucial as it allows shooters to accurately aim their weapon and coordinate their hand movements to pull the trigger at the right moment. Without eye-hand coordination, shooters would struggle to align their sights with the target and consistently hit their mark.
9.
What is the smallest type of firearms?
Correct Answer
D. Hand gun
Explanation
A hand gun is the smallest type of firearms. It is a compact and portable firearm that is designed to be held and operated with one hand. Hand guns are typically used for self-defense and have a shorter barrel compared to other types of firearms like rifles or shotguns. They are commonly used by law enforcement officers and civilians for personal protection.
10.
What is hit when a firearm is fired?
Correct Answer
A. Target
Explanation
When a firearm is fired, the hit is made on the target. The target is the object or area that the shooter aims at and intends to strike with the bullet. The bullet is the projectile that is propelled out of the firearm when it is fired. The load refers to the ammunition or cartridge that is loaded into the firearm. The trigger is the mechanism that is pulled to initiate the firing of the firearm.
