Final answer:
In pistol shooting, all types of targets including bullseye, moving, and silhouette are used. Gun sights are calibrated for specific ranges, and shooting at a different range than what the gun is sighted for without adjusting the aim will result in a lower impact point due to gravity. Larger muzzle velocity and air resistance are factors that can affect bullet trajectory.
Step-by-step explanation:
In pistol shooting, various types of targets can be used, including a. Bullseye targets, b. Moving targets, and c. Silhouette targets. Therefore, the correct answer would be d. All of the above. Each type of target tests different shooting skills, such as precision, timing, and marksmanship. For example, bullseye targets are typically used to measure accuracy and precision, whereas moving or silhouette targets can be used to simulate real-life shooting scenarios and test the shooter's ability to aim and fire under different conditions.
The concept of precision and accuracy in measurements is analogous to hitting a target in shooting. A precise but inaccurate set of measurements is like a cluster of shots that are close together but do not hit the bullseye. A both precise and accurate set of measurements would be like shots that are not only close together but also centered on the bullseye. A set of measurements that is neither precise nor accurate is like shots that are scattered all around the target area, far from both each other and the bullseye.
Gun sights are calibrated to account for ballistics and gravity; they allow shooters to aim directly at a bullseye at a certain range. If a gun is sighted for 100.0 m but used to shoot a target at 150.0 m without adjusting the aim, the bullet will hit lower due to gravity pulling it down over the longer distance. The magnitude of this drop depends on the muzzle velocity and the time the bullet is in flight. With a larger muzzle velocity, the bullet would travel faster, reducing the time for gravity to act on it, so it would drop less over the same distance. However, air resistance also plays a role; the faster the bullet travels, the more air resistance it encounters, which can slow it down and increase the drop over a given distance.
