Basic Units of MeasurementAstronomers use metric units, and in particular the cgs (centimeter-gram-second) system.1 DistanceThe basic unit of distance is the centimeter (cm). There are 100 centimeters in a meter and 1000 meters in a kilometer. The meter was originally defined in terms of ...
The kilogram is the metric unit of mass, not weight. Mass is the fundamental measure of the amount of matter in an object. Unfortunately, no absolutely unchangeable standard of mass has yet been found on which to standardize the kilogram. The kilogram is therefore defined as the mass of a ...
The default units for length, energy, time, and mass are cm, MeV, shakes (1 × 10−8s), and grams, respectively (MCNP manual 7.1.6). Comment cards begin with a c followed by a space and may be anywhere after the title card. Each card may also have a comment at the end started...
Definitions of SI unit.a complete metric system of units of measurement for scientists; fundamental quantities are length (meter) and mass (kilogram) and time (second) and electric current (ampere) and temperature (kelvin) and amount of matter (mole) and luminous intensity (candela) ...
ρ = Mass density of fluid A = Cross-sectional area of restriction The fluid “resistance” of a restriction depends on several variables: the proportion of kinetic energy lost due to turbulence (k), the density of the fluid (ρ), and the cross-sectional area of the restriction (A). In...
In multicellular organisms, the DNA is packaged into a nucleoprotein complex called chromatin. The chromatin consists of DNA wrapped around a core of highly basic proteins called histones. The fundamental unit of the chromatin is called a nucleosome, which consists of 146 base pairs (bp) of DNA...
