Yes
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
What do you mean with "unit of mac"? If you mean "unit of mass", the official unit, used worldwide, is the kilogram.
R. N. Mohapatra has written: 'Massive neutrinos in physics and astrophysics' -- subject(s): Mass, Masse, Neutrino astrophysics, Neutrino-astronomie, Neutrinos 'Unification and supersymmetry' -- subject(s): Grand unified theories (Nuclear physics), Particles (Nuclear physics), Supersymmetry
sideways M in physics is the greek letter sigma which means sum. other m's can mean mass those are the only m's i know of.
In physics, momentum refers to the quantity of motion an object has, determined by its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction.
mass=density*volume
In physics, mass is a measure of the amount of matter in an object. It is a fundamental property of an object that determines how it responds to forces like gravity. The SI unit of mass is the kilogram.
In Nuclear Physics, A stands for atomic mass number. Atomic number is the number of protons and neutrons present in the nucleus of a given atom. Basically it tells us about the mass of the atom, as nucleons are the only sub-atomic particles which have mass. Nucleons mean neutrons and protons.
In terms of physics, MV typically refers to momentum, which is the product of an object's mass (m) and velocity (v). Momentum is a vector quantity that represents the motion of an object. The greater the mass or velocity of an object, the greater its momentum.
"925 N" typically refers to a measurement of force, specifically 925 Newtons. The Newton (N) is the SI unit of force, defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. Therefore, 925 N represents a significant amount of force that can be applied in various physical contexts, such as engineering or physics.
The unit for weight in physics is the newton (N).
It explained law of conservation of mass and law of constant proportion and laid foundation to atomic physics n chemistry...
