What unit is N divided by M?

The newton/meter is the SI-derived unit for surface tension. One newton per meter is the same as one newton per meter. The newton is a very large force, and it takes a lot of energy to create a newton's force. Thus, the newton is also called a "frictional" or "contact" unit.

In chemistry, the newton is used as a measure of reaction force. In physics, the newton is used to describe forces between objects, including gravity. A body that is able to apply a newton of force will be able to lift or pull another object that is equal in mass to itself.

When two objects with mass are pulled together, they experience an attractive force due to quantum mechanics. This is called the "van der Waals force" and has nothing to do with classical mechanics; it is a quantum effect. For atoms and molecules, the magnitude of this force is so small that it can only be measured experimentally.

Atomic masses are very close to the mass of a proton or a neutron, which are both types of particle called "leptons". Leptons are the most common type of particle in the universe. They account for about 95% of the matter in the cosmos.

What is the unit of magnitude?

The SI Units system selects seven magnitudes to form a basic set (metre, kilogramme, second, ampere, kelvin, mole, and candela), and all others (e.g. hertz, newton, volt, radian) are regarded as deriving from this set by appropriate definitions involving only multiplication, division, differentiation...

In other words, every quantity can be expressed in terms of one or more elements of the basic set, and any number multiplied by an element of the basic set will again yield a valid expression for a quantity.

For example, we can express the velocity of light in vacuum as c = 299792458 m/s, which means that it is equal to the metre times some number less than one. We know that 1 metre equals 39.37 inches, so c must be divided by 39.37 to obtain a value for m.

Thus the unit of velocity is metres per second, or m/s. All physical quantities can be expressed in terms of these seven units, which are defined to have the following values:

M = 0.000001 kg

S = 1000 m/s

A = 0.0011 eV/(GeV·cm)

K = 1.3806504 × 10^-23 J/K
