What else can I help you with?
What are the SI units for speed of light?
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
What is the SI units of measure?
The SI has seven base units (kilogram, meter, second, ampere, kelvin, mole, candela), and lots of derived units - for example, meter/second for speed/velocity, coulomb = ampere x second for electrical charge, etc.
What is the formula for acceleration and what would be an example of an acceleration units?
The basic formula for acceleration is the one that defines acceleration, as the rate of change of speed: a = dv/dt. For the case of constant acceleration, this is simply (change of velocity) / time. The unit is any unit of speed by a unit of time; in the SI that would be (meters / second) / second, usually written as meters / second squared.
What does the SI unit for speed, m/s, stand for?
The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
What are subsidiary quantities and units in SI?
Subsidiary quantities are derived quantities that are defined in terms of the base quantities in the International System of Units (SI), such as area and volume. Units for these quantities are formed by multiplying or dividing the base units according to their definitions. For example, the unit of speed, meter per second (m/s), is a derived unit formed from the base units of length (meter) and time (second) in SI.
How many units are in the SI system and can i see them?
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
What is the SI unit of a test tube holder?
SI units refer to normalised sets of units, not of equipment. For example. The SI unit for length is metre, volume is litre etc.
What are the fundamental and derived units?
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
How are SI units used in the Unitde States?
Lots of different ways. For example, the legal definition of the U.S. standard units (foot, gallon, pound, etc.) are in terms of SI units.
What the measurement of units?
The SI has seven base units (kilogram, meter, second, ampere, kelvin, mole, candela), and lots of derived units - for example, meter/second for speed/velocity, coulomb = ampere x second for electrical charge, etc.
Are SI units and standard units the same?
Yes they are.* * * * *No, they are not. A foot, for example, is a standard unit of the Imperial system.
What unit of measure is NOT used in the International System of Units?
Lots of units used in the United States are not in the SI - for example the units of length (inch, foot, etc.), of volume (quart, gallon, cubic feet), of mass (avoirdupois pound, ton), etc.In the international community, some of the units commonly used aren't in the SI either - for example, most units of time (minutes, hours, days, weeks, years), the unit of temperature (Celsius, also called Centigrade), units of speed such as kilometers per hour, and the kWh as a unit of energy.
