Answer:
Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
AND
Examples:
Revolution of Earth around the sun.
Revolution of moon around the earth.
Velocity of a satellite around the earth.
Velocity of a car while driving.
Velocity of a ball when hitted with a bat.
Velocity of water coming from a tap.
Velocity of the train .
Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems.. Formula = ˙ is the characteristic velocity (e.g. m/s, ft/s) is the chamber pressure (e.g. Pa, psi)
It will make the image less bright because reducing the aperture will only decrease the amount of light itself, not the image formed.
<h3>
What does photography's aperture mean?</h3>
The aperture is the movable lens opening that regulates how much light may enter the camera.
For you to get nice exposures, you must learn how to appropriately modify these three settings according to your location and subject. An aperture is a hole or opening that allows light to pass through it in the field of optics.
More specifically, the cone angle of a group of rays that focus in the image plane depends on the aperture and focal length of an optical system.
The ray bundles are often constrained by a number of apertures or features in an optical system.

Collection process is the process of tracking evidence from collection to trial and after, when it is<u> returned to its owner or destroyed</u>.
<h3>What is collection and preservation of evidence?</h3>
When the crime scene has been fully recorded and the locations of the evidence have been identified, the collecting phase may start. Usually, gathering the most fragile or easily lost pieces of evidence comes first in the collecting process. Additionally, any evidence or things that need to be transported might be given special care. The collection process might then carry on logically or along the path taken by the crime scene. If the investigator is uncovering layers of evidence that were previously undocumented because<u> they were concealed from view</u>, further photos should be taken.
The majority of the evidence will be packaged in paper containers such packs, envelopes, and bags. Indestructible, leak-proof containers can be used to transport liquid substances.
