Hace 2 días · Combinations of base and derived units may be used to express other derived units. For example, the SI unit of force is the newton (N), the SI unit of pressure is the pascal (Pa)—and the pascal can be defined as one newton per square metre (N/m 2).

The unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The name pascal was adopted for the SI unit newton per square metre (N/m2) by the 14th General Conference on Weights and Measuresin 1971.
The pascal can be expressed using SI derived units, or alternatively solely SI base units, as: 1. 1Pa=1Nm2=1kgm⋅s2=1Jm3{\\displaystyle {\\rm {1~Pa=1~{\\frac {N}{m^{2}}}=1~{\\frac {kg}{m{\\cdot }s^{2}}}=1~{\\frac {J}{m^{3}}}}}} where N is the newton, m is the metre, kg is the kilogram, s is the second, and J is the joule. One pascal is the pres...
The unit of measurement called an atmosphere or a standard atmosphere (atm) is 101325 Pa (101.325 kPa). This value is often used as a reference pressure and specified as such in some national and international standards, such as the International Organization for Standardization's ISO 2787 (pneumatic tools and compress...
The pascal (Pa) or kilopascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch (psi) unit, except in some countries that still use the imperial measurement system or the US customary system, including the United States. Geophysicists use the giga...

Hace 3 días · Young's modulus , the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise.
Hace 3 días · In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it.

Hace 3 días · C has been standardized by ANSI since 1989 ( ANSI C) and by the International Organization for Standardization (ISO). C is an imperative procedural language, supporting structured programming, lexical variable scope and recursion, with a static type system.
25 de may. de 2023 · Biografía. Blaise Pascal nació en Clermont Ferrand en 1623. Educado por su padre, que ocupaba un importante cargo público, pronto dio muestras de su genio, especialmente en cuestiones matemáticas, y a los 16 años compuso un Ensayo sobre las cónicas. Inventó una «máquina aritmética», en cuya realización trabajó muchos ...
