What is the unit of length in SI units?
Meter Standard meter is the bar of an alloy of platinum and iridium kept under controlled conditions at the " International Sureau of Weights and Measures" near paris.
What is the SI unit for diameter of an object?
Diameter is measured linearly so officially, it would be meters. However any unit derived from the meter (cm, mm, etc.) would also be acceptable. New: Let's start off with the smallest practical metric unit of length, the millimerte (mm).One inch contains 25.4 mm.10 mm is equal to one centimetre (cm) or 2.54 inches100 cm is equal to one metre (m) or 1.09 yards1000 m is equal to one kilometre (km) or 0.62 miles
What object did French scientists use to determine the length of a meter?
Originally (around 1871) the length was established by a bar of a certain length, which represented one ten-millionth of the distance from the North Pole to the Equator. In 1960, it was defined physically by an unchanging wavelength of light: "1,650,763.73 wavelengths of the orange-red emission line in the electromagnetic spectrum of the krypton-86 atom in a vacuum." This is still a very accurate definition. Since 1983, it has been defined as "the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second." The second is currently defined relative to the radiation emission wavelength of cesium-133, which is a fixed length.
What is the basic metric unit of linear measurement?
Length . . . meterMass . . . kilogramTime . . . secondElectric current . . . ampereThermodynamic temperature . . . kelvinAmount of substance . . . moleLuminous intensity . . . CandelaAll the other units are derived from these.According to Halliday and Resnick ("Fundamentals of Physics", Wiley, 1974, p.8) "Three different systems of units are most commonly used in science and engineering. They are the meter-kilogram-second or mks system, the Gaussian system in which the fundamental mechanical units are the centimeter, the gram, and the second (a cgs system), and the British engineering system (a foot-pound-second or fps system).According to Masterton and Slowinski ("Chemical Principles", WB Saunders Company, 1973, pp. 4-5) "The unit of mass used most frequently in chemistry is the gram, which represents one thousanth of the mass of a platinum-iridium block kept at the International Bureau of Weights and Measures (1 kg = 103 g)."So unless you are talking about a system of units, the unit of mass is the gram.Length; millimetre (mm), centimetre (cm), metre (m)1 metre = 3.28 feet
Where is the international standard liter kept?
The international standard for a liter is kept in Paris, France.
What canges will happen to a bowl of ice and water kept at exactly zero degree celsius?
The water part will turn into ice.
What changes will happen to a bowl of icw and water kept at exactly zero degree celsius?
No change will happen. Rajeev jha (delhi)
Where is the correct si unit for meter is kept?
As long as the standard was a physical object, it was kept in Paris. But the meter is now defined in terms of the speed of light, so it can be reproduced to any arbitrary degree of precision in any sufficiently well-equipped laboratory, and no longer needs to be kept anywhere.
What is the optimum temperatures of Serratia marcescens?
Serratia marcescens grows best at temperatures between 25-35 degrees Celsius, with an optimum temperature around 30 degrees Celsius. Below 10 degrees Celsius, growth is significantly reduced, and above 40 degrees Celsius, growth may be inhibited.
What is the unit of length in SI units?
Meter Standard meter is the bar of an alloy of platinum and iridium kept under controlled conditions at the " International Sureau of Weights and Measures" near paris.
What temperature is the body kept at?
37 degrees Celsius
What are two weather devices that must be kept outside?
a wind meter and a rainfall meter
What is the temperature in degrees Fahrenheit of a freezer kept at -20 degree Celsius?
The temperature in degrees Fahrenheit of a freezer kept at -20 degrees Celsius would be -4 degrees Fahrenheit. This can be calculated by using the formula: °F = (°C x 1.8) + 32. So, (-20°C x 1.8) + 32 = -4°F.
What temperature does vitamin c get destroyed?
Vitamin C is the most unstable vitamin which can be easily denatured. It should be kept at under 70 degree Celsius to avoid damage caused by the heat.
What temperature should ice be kept?
At about -7 degrees celsius.
Where is the perfect meter kept?
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
What changes will happen to a bowl of ice and water kept at exactly zero degree Celsius?
If the bowl of ice and water is kept at exactly zero degrees Celsius, the ice will remain in equilibrium with the liquid water. The ice might slowly melt into water, but at the same rate it will refreeze into ice due to the balance between freezing and melting processes at this temperature.
