# How was the length of a meter redefined in the year 1983?

# How was the length of a standard meter defined in the year 1791?

In the 18th century it was felt that a standard unit of length was needed. The French Academy of Sciences decided in 1791 that the meter would be defined by the dimensions of the planet earth..
The metre would be a unit of length such that Earth's meridian line (a line linking the equator with the …north pole) was equal to ten million meters. Over the following years measurements of the meridian line that passes through Paris were attempted, so that a standard meter could be cast in metal. (MORE)

# How was the length of a standard meter redefined in 1983?

Originally, a metre was defined as 1/10,000,000th of the distance from the Earth's equator to the North pole. Since 1983 it has been defined as:.
the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458th of a second. .

# How was the length of a standard meter defined in the year 1719?

Answer .
The standard meter (metre) was not defined in 1719. It was not until the 1790's that it was set as a standard. It was proposed that the metre would be defined as one ten millionth the distance from the earth's north pole to the equator as measured along a meridian. There is a good explan…ation here:.

# In 1983 what changed about the length of the meter?

Answer \n.
\nThe French were the first to define the length of a meter by using a alluminium/platinum alloy bar of a meter length at 25 degrees Celcius. This however is very inaccuracte for quantum measurements as the length of the bar would change two much depending on how you hold it. A better …measurement found in 1983 is the distance that light travels in a vacuum in 1/229,792,458ths of a second. (for those of us with a decent knowledge of relativity that measurement is taken in the rest frame). Crazy I know but at least this way any body in a good physics lab can reproduce this distance without the use of some silly French rod. (MORE)

# Where did the length of a meter come from?

The meter was defined in 1790 as one ten-millionth (10 to the -7th power) of the Earth's quadrant passing through Paris. It was redifined - because the earth is not a sphere, after all, but an oblate spheroid - in 1960, as equal to 1,650,763.73 times the wavelength in a vacuum of the orange-red radi…ation of krypton 86. In other words, the meter is a length totally unrelated to anything in human experience, which supports the assertion that only a machine could love the Metric System. (MORE)

# How the method of establishing the scientific length of meter has change over the last 200 year?

It comprises a system of units of measurement devised around seven base units and the convenience of the number ten. The SI was established in 1960,[3] based on the metre-kilogram-second system, rather than the centimetre-gram-second system, which, in turn, had several variants. The SI has been decl…ared to be an evolving system; thus prefixes and units are created and unit definitions are modified through international agreement as the technology of measurement progresses, and as the precision of measurements improves..

# What is the average length of an anaconda in meters?

Anaconda's are one of the world's largest & longest snake species. They are known to reach sizes of over 6.6 meters (22 feet) long on an average.

# What is the length of an edge of a cubic meter?

A cubic meter is a unit for volumetric measurement (like fluid ounce). The volume of an object is dependent on its geometry. Thus, your question can only be answered for a cube.

If …your question is regarding a cube having a volume of a cubic meter (1 cu. m), then the answer is 1 meter. This is so because the volume of a cube with side (or edge) of length ' s meter ' is s^3 cubic meter (that is, s x s x s cubic meter). (MORE)

# What is length and of 28 square meters?

The area is not sufficient information to determine the length and width. First of all, there is no reason to suppose that the area is rectangular as opposed to circular or triangular or some other simple or complicated shape. Even if, on the basis that the question asks for length and something e…lse, you assume that it is a rectangle, there are infinitely many possible answers. Let L be any length greater than or equal to sqrt(28) metres and let B = 28/L metres. Then the area of a rectangle with length L metres and breadth B metres is L*(28/L) = 28 sq metres. Now there are infinitely many numbers greater than sqrt(2* and so an infinite number of possible solutions. . (MORE)
