The pellets in a shotshell start to spread or scatter as soon as they are fired. This dispersion will increase as the pellets travel farther. Shotgun barrels feature a choke to regulate this pellet pattern. The shotgun barrel's choke is the constriction at the muzzle end.
How long is a shot string?
At 20 yards, it can be roughly 5 feet long, and at 30 yards, it can be 8 feet long. The variance is brought on by the pellets' distortion as they move along the barrel.
The full choke features the tightest shot pattern and is the tightest choke. The pellets are kept together for a longer distance thanks to this choke. It is typically used for shots that are further than 40 yards.

An indicator of average kinetic energy is temperature. Temperature is directly proportional to Kinetic energy of the molecules of an element.
Answer:
Temperature
Explanation:
The energy contained by a body due its motion is known as kinetic energy.From kinetic theory of gases, the average kinetic energy is proportional to temperature. More the temperature, more would be the speed of the particles. Gases having same temperature would have same average kinetic energy.
Thus, an indicator of average kinetic energy is temperature.
The image formed by the convex lens is real, located 10.91 cm to the right of the lens, and is inverted. The ray diagram would show rays from the object converging at the image point after passing through the lens.
In order to draw a ray diagram and find the location of the image for an object placed 30.0 cm to the left of a convex lens with a focal length of +8.0 cm, we first utilize what is known as the lens formula, which is 1/f = 1/do + 1/di. Here, f is the focal length of the lens, do is the object distance, and di is the image distance.
In the given question, the object distance (do) is -30 cm (the negative sign indicates that the object is on the same side of the lens as the light source), and the focal length (f) is +8 cm. Plugging these values into the lens equation, we find that 1/di = 1/f - 1/do = 1/8 - 1/(-30). Solving this, we get di = 10.91 cm.
This positive value for di means the image is real, meaning it can be projected onto a screen, and appears on the opposite side of the lens from where the object is. The magnitude of the image distance indicates the image is 10.91 cm from the lens.
To determine the orientation of the image, we use the magnification formula, m = -di/do. Substituting the given values into this formula, we get m = -10.91 / -30 = +0.36. Since this value is positive, the image is inverted. The image would appear smaller than the object because the absolute value of the magnification is less than 1.
