Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.

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)
<span>Products that customers consider essentials or necessities tend to have less elasticity than products viewed as luxury or discretionary. If a customer believes he needs a certain product for survival, quality of life, or pleasure, he is more likely to stretch a bit to purchase the item if the price goes up. On the contrary, a product viewed as optional is a less likely purchase as the price increases because the customer believes he can live without it.Customer OptionsThe more options a customer has to meet a particular functional or emotional need, the more elastic a product's demand. This is why a company with a monopoly has a huge advantage. Customers don't have options and feel compelled to buy from the given provider. In highly competitive industries, price differentials are usually less among competing brands because of the ability customers have to select lower-priced alternatives. A closely related factor is the cost of switching brands. Cell phone customers often wait to change providers to avoid penalties if they are obligated to service contracts.
