what would happen if there was no use of SI system in all over the world by the general conference of scientist mention any three assumptions.​

Answers

Answer:

he International System of Units, universally abbreviated SI (from the French Le Système International d'Unités), is the modern metric system of measurement. The SI was established in 1960 by the 11th General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures). The CGPM is the international authority that ensures wide dissemination of the SI and modifies the SI as necessary to reflect the latest advances in science and technology.

The CGPM is an intergovernmental treaty organization created by a diplomatic treaty called the Meter Convention (Convention du Mètre, often called the Treaty of the Meter in the United States). The Meter Convention was signed in Paris in 1875 by representatives of seventeen nations, including the United States. There are now 51 Member States of the Meter Convention, including all the major industrialized countries. The Convention, modified slightly in 1921, remains the basis of all international agreement on units of measurement.

The Meter Convention also created the International Bureau of Weights and Measures (BIPM, Bureau International des Poids et Mesures) and the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures). The BIPM, which is located in Sèvres, a suburb of Paris, France, and which has the task of ensuring worldwide unification of physical measurements, operates under the exclusive supervision of the CIPM, which itself comes under the authority of the CGPM.  

The CGPM consists of delegates from all the Member States of the Meter Convention and currently meets every four years (the 23nd CGPM took place in November, 2003). The CIPM consists of eighteen members, each belonging to a different Member State; it currently meets every year, usually in September or October at the BIPM.  

Suggested modifications to the SI are submitted to the CGPM by the CIPM for formal adoption. The CIPM may also on its own authority pass clarifying resolutions and recommendations regarding the SI (these resolutions and recommendations usually deal with matters of interpretation and usage).  

To assist it in its broad spectrum of technical activities, the CIPM has set up a number of Consultative Committees (Comités Consultatifs). These committees provide the CIPM with information on matters that it refers to them for study and advice. Each Consultative Committee, the Chairman of which is normally a member of the CIPM, is composed of delegates from national metrology institutes such as NIST, specialized institutes, and other international organizations, as well as individual members. The Consultative Committee for Units (CCU, Comité Consultatif des Unités), which was set up in 1964 and which replaced the Commission for the System of Units set up by the CIPM in 1954, advises the CIPM on matters dealing with the SI. In particular, the CCU helps to draft the BIPM SI Brochure, of which NIST Special Publication 330 (SP 330) is the U.S. version.

The BIPM SI Brochure (9th Edition) was published on May 20, 2019. The corresponding editions of NIST SP 330:2019 is now available. An updated edition of SP 811 will be published soon that reflects the changes incorporated in the BIPM SI Brochure (9th Edition). Electronic copies of SP 330:2019 and SP 811:2008 are available online from the Bibliography.

The U.S. delegate to the CGPM is often the NIST Director and the U.S. member of the CIPM is Dr. Willie E. May, former Director of NIST and currently the Director, Special Research and Training Initiatives, College of Computer, Mathematical and the Natural Sciences, University of Maryland, College Park. The current NIST delegate to the CCU is Dr. Peter Mohr of the NIST Physical Measurement Laboratory. Questions concerning the more fundamental aspects of the SI and subtle aspects of proper SI usage may be directed to him at the following address:

How do human actions negatively impact ocean ecosystems?
A. Burning of fossil feels increases the acidity of the oceans
B. Increased tourism in the sailors disrupt the ocean environment
C. The ocean ecosystems are not impacted by human action
D. Reducing carbon dioxide emissions threatens ecosystems and food supplies

Answers

A. Burning fossil fuels
Explanation- Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognized for the biodiversity and continuation of marine life forms.

Marine pollution results from the introduction of industrial, agricultural, and residential wastes into the ocean. The majority of this waste (80%) comes from land-based activity, although marine transportation also significantly contributes as well.Much of the land-based pollution is what is called nonpoint source pollution, meaning the pollutant results from several diffuse sources rather than a single, direct source

The atmosphere the air of Earth (and some other planets) and is made of 78% nitrogen, 21% oxygen and 1% of a mix of others. It is the standard base of measurement of atmopsheric density/pressure on varying altitudes and other planets.

The crust is a solid rock that floats above the liquid mantle. It is made up of large tectonic plates that seprate or impact one another, creating trenches and mountains.

The mantle is a large layer of liquid rock 2,900km in size. Convection currents move the molten rock and material around (And that's where volcanoes obtain their characteristic red-hot, molten flowing rock).


Then there's the outher core. It is a 2,300 kilometer liquid ocean of iron and cobalt. Convection currents exist here too as in the mantle, though more frequent.

Ultimately there's the inner core. It's a dense, hot solid ball of iron and nickel. At least 5,400+ Celsius, it is hotter than the surface of the Sun and well, our gravity. Oh, and it is also super dense and has a high pressure.

Hey there! I'm happy to help!

Absolute location is identifying exactly where you are on Earth's surface based on data such as an address, coordinates, etc.

Relative location is identifying where you are in relation to other things. For example, you could say that live next to the school or east of the water tower.

We see that GPS, addresses, and Internet are going to give data that can give you an absolute location, not relative. A GPS will guide you to a specific place based on the address and an address gives you a specific location on Earth's surface. The Internet can give you coordinates and addresses.

This leaves us with mental maps of an area. You don't need to look things up or use data to identify where you live relative to other things. You just know in your mind that you live next to a park, the church, the fire station, etc.

So, most people use relative location on a daily basis by using B. their mental maps of an area.

A rectangle has a perimeter of 8x^2+10x-6 and has a width of 3x^2+4x, what is the length of the rectangle

Answers

Answer:

The length of the rectangle is x^2 + x - 3.

Explanation:

The length of the rectangle is x^2  +  x - 3.

Description of a rectangle

A rectangle is a four-sided shape. The opposite sides of a rectangle is equal. The sum of angles in a rectangle is equal to 360 degrees.

The perimeter of a rectangle is the distance round a rectangle. The perimeter of a rectangle = 2(length + width).

Determination of the length of the rectangle.

8x^2+10x-6 = 2(3x^2+4x + length)

Divide both sides of the equation by 2

4x^2 + 5x - 3 = 3x^2 + 4x + length

Length = (4x^2 + 5x - 3) - (3x^2 + 4x)

Length = x^2  - x - 3
