Conventional Prompt Strike ( CPS ), formerly called Prompt Global Strike ( PGS ), is a United States military effort to develop a system that can deliver a precision-guided conventional weapon strike anywhere in the world within one hour, in a similar manner to a nuclear ICBM. [1] [2] Such a weapon would allow the United States to respond far ...
Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute. Counts are only manifested in the reading of the measuring instrument, and are not an absolute measure of the strength of the source of radiation. Whilst an instrument will display a rate of cpm, it does not have to detect counts for one ...
Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals ( sound ), radio waves, and light . For example, if a heart beats at a frequency of 120 times per minute (2 hertz), the period—the interval between beats—is half a ...
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. [1] [a] The hertz is an SI derived unit whose expression in terms of SI base units is s −1, meaning that one hertz is the reciprocal of one second. [2] It is named after Heinrich Rudolf Hertz (1857–1894 ...

The SI unit of dynamic viscosity is the newton-second per square meter (N·s/m 2), also frequently expressed in the equivalent forms pascal-second (Pa·s), kilogram per meter per second (kg·m −1 ·s −1) and poiseuille (Pl). The CGS unit is the poise (P, or g·cm −1 ·s −1 = 0.1 Pa·s), named after Jean Léonard Marie Poiseuille.
Civilian Public Service firefighting crew at Snowline Camp near Camino, California, 1945. The Civilian Public Service ( CPS) was a program of the United States government that provided conscientious objectors with an alternative to military service during World War II. From 1941 to 1947, nearly 12,000 draftees, willing to serve their country in ...
Viscometer. A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer. [1]
