What is the name for the narrowing at the muzzle end of a shotgun barrel?

Answers

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 _____. pressure volume diffusion temperature

Answers

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.

An object is 30.0 cm to the left of a convex lens with a focal length of +8.0 cm. Draw a ray diagram of the setup showing the location of the image. Calculate the distance of the image from the lens. Is the image upright or inverted?

Answers

The distance should be 11 cm and the image will be inverted (and smaller)
I used the Lens Equation:
(1)/(obj.)+ (1)/(im.)  = (1)/(f)
Where:
obj. is the distance of the object
im. is the distance of the image
f is the focal length

Final answer:

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.

Explanation:

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.

In the series circuit below the power source is a 9-volt battery and three resistors are R1 = 7 ohm, R2 = 9 ohm and R3 = 2 ohm. What is the total resistance in the series circuit? R1 7 ohm + R2 9 ohm + R3 2 ohm = 18
Is this correct?

Answers

Yes indeed. You're on your way. In a series circuit, the total resistance is the sum of the individuals no matter what order they're in. Now, if the question goes on to ask what is the current in the circuit, that will be the source voltage divided by the total resistance that you have calculated.

Which kind of waves are sound vibrations made of?transverse
circular
longitudinal
latitudinal

Answers

The answer is longitudinal. There are two types of waves: transverse and longitudinal. Transverse waves are those whose vibrations are perpendicular to the direction of the wave. Longitudinal or compression waves are those whose vibrations are in the same direction as the wave. Sound is caused by the compression of vibrations of molecules.

Answer:

longitudinal
